Double Chess 16 x 8. On 16 by 8 board. (16x8, Cells: 128) [All Comments] [Add Comment or Rating]

Hanga Roa. A chess variant inspired by the people of Easter Island. (9x9, Cells: 81) [All Comments] [Add Comment or Rating]
Karen Robinson wrote on Fri, Mar 16, 2018 05:20 AM UTC:Excellent ★★★★★

This game has everything I love in a boardgame:  simple rules, interesting play, a fun theme, and unusual mechanics.   The stone throwing reminds me a bit of Amazons, but using the stones as roads is completely new to me.  There's a choice at every turn whether to try to build your own road, or destroy your opponent's road.  

There's also a bit of a hint of hnefatafl with the two goals of surrounding and immoblizing the other piece, and reaching the far side of the board.

I followed the link in the article and read about the history of the Moais, how the inhabitants descended into warfare as the island was deforested, and how they destroyed the Moais of other inhabitants as part of that warfare, which adds a darker tone to the theme.  

What a fascinating and unusual game.  I really love this one.  I wish it were more widely known.  
Would the designers mind if I listed it on boardgamegeek, with a link back to this page?  


Deception Chess. Each piece has two identities, Cloak and concealed Base.[All Comments] [Add Comment or Rating]
David Cannon wrote on Tue, Apr 3, 2018 02:08 AM UTC:Excellent ★★★★★

I like this concept. Pieces can suddenly "come out" as something else. I suppose this could be called a variant of chess with incomplete information — as the "true identity" of each player's pieces is known to the respective players, but not to their opponents. At the same time, cloaking forces the player to decide in advance which piece will morph into what, preventing arbitrariness. 


CHESSAGON. CHESSAGON® is like traditional Chess, but with Triangles, with one new additional piece named the Duke.[All Comments] [Add Comment or Rating]
David Cannon wrote on Mon, Apr 23, 2018 02:42 PM UTC:Good ★★★★

I'm delighted to see a variant based on triangular cells, rather than squares or hexagons. Not that there's anything wrong with squares and hexagons, but that triangles are under-explored and under-exploited. Christian Freeling and Graeme Neatham invented several trigonal chess games, and I contributed a couple of my own (Rotorblades Chess and Rotorblades Fusion Chess). And of course there's Klinzha. But for the most part, inventors seem to give triangular boards a miss. 

I see that Chessagon tries to be as faithful as possible to traditional chess. That's one "pole" of the chess variant universe; the other "pole" is games like Arimaa, which barely qualify as chess variants. My own taste is for something in the middle —I like games that extrapolate the moves of the traditional pieces to the new geometry, but also introduce pieces that take advantage of the new geometry in a way that the familiar pieces cannot. The only piece of this nature to do so in Chessagon is the Duke, and I think there is room for more unusual pieces that would create interesting possibilities for play. 


Palace Shogi. A complicated hybrid of Shogi, Xiang Qi, and Chess.[All Comments] [Add Comment or Rating]

Hi Silvia! Thank you for introducing us to this exotic blend, which is one of the best I've seen. I've seen a few east-west hybrids before, and even tried inventing a couple of them myself, which I never published here because I didn't like them very much — they seemed to be neither fish nor fowl. But yours blends them in a way that doesn't seem forced or stretched, and I really like that!


Dream Chess 46. 46-squasre variant played from opposite corners of a FIDE board with the other corners removed. (8x8, Cells: 46) [All Comments] [Add Comment or Rating]
George Duke wrote on Fri, Apr 27, 2018 01:36 AM UTC:Good ★★★★

This is a straightforward CV by Gilman.  To suit the constricted board, he decides to use Shogi promotees for Bishop and Rook, adding Wazir and Ferz respectively.  Pawns are Centennial-acclaimed Quadra-pawns.  Some restriction on Knight at inside corners.  That's it.  Should be playable enough short games.  

But the piece in right corner needs correction to King.


Neutral Subject Chess. Most pieces start neutral, and players compete to recruit them. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
George Duke wrote on Fri, Apr 27, 2018 06:08 PM UTC:Excellent ★★★★★

Parton made Neutral King in 1953, where player has own orthodox pieces but the King is co-owned and

yet has to be checkmated.  Simple and elegant.  Most of Gilman's CVs are hurt by overcomplications in

piece-moves, odd board sizes, too many special rules, or attempt hybridizing Eastern chesses with forced

templates.  Once in a while he strikes paydirt such as AltOrthHex idea of splitting up the hexagonal Rook

into two, though nobody has really done anything with that either.  

Neutral Subject realizes that Parton's Mutator has wider applicability. Here player only has King and Queen to begin.  Neutral pieces get moved and then assigned to one side or the other.  The criterion to assign is applied at end of each turn according to hypothetical attack of each 'Neutral' on any piece already assigned.  Who wouldn't want more pieces rather than fewer? Many other CVs could be made in this genre of the pieces on board not belonging to either army initially.  

Charles' novel CV invention, expanding on Parton, gets somewhat awkward explanation in his essay. Like Aronson and Howe with Rococo, great idea is not followed up with clear summary fully disambiguating.

Still in all, there could be other ways to set up the bazaar of recruitment to build the forces in subvariants and new CVs this type of possible breakthrough Mutator.

 

 


Amalgamated Chess. Incorporates some aspects of historical variants, but uses only usual equipment. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Chris Chradle wrote on Sun, May 6, 2018 08:15 PM UTC:Good ★★★★

Still two things: "The King may not move back over the river; however, he still delivers check backwards." When the black king is on f4, the white king can't move to f5 giving the king on f4 check (it would move into check itself). I think you mean that when there is a black king on f4, the white king can't move to f5 or e5.

On e1 and d8 must be generals in the starting position, musn't they?


PantherChess. Variant of Capablanca Chess with two Panthers per side replacing the Archbishop and Chancellor.[All Comments] [Add Comment or Rating]
Chris Chradle wrote on Sun, May 6, 2018 08:26 PM UTC:Good ★★★★

The Panther is a very interesting piece. It has similar characteristics like the knight. After two moves it covers a similar distance like the knight. The leaps ar (1,1), (0,2), (1,3), (0,4) and (3,3). The only difference is that the night can't go (0,6) so the operating range of the Panthter should be slightly better.

New-Chess. Variant on 10 by 10 board with combination pieces. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
George Duke wrote on Mon, May 7, 2018 05:02 PM UTC:Good ★★★★

Fifteen years til the first comment and rating now.

Sava made New-Chess by 1973, in time for the second edition of Gollon's book.  There are Marshall RN (but not Cardinal BN), Amazon RBN and Gnu N-Camel.  Then Betza and Cohen came up with Tutti-Frutti in 1978 with the 'Capablanca two' and Amazon again, this time on 8x8.  So it appears Betza and Cohen got some inspiration from then recent New-Chess and thought it important to put their similar piece mix on little 8x8. New CVs were fewer and further between those decades. In fact, Betza always designed 1970s through 2003 on 8x8 with two exceptions.  His 'Outrigger' article adds files to get 8x10, and Chess on Really Big Board has four 8x8 boards for 256 squares.*

No allowing in New-Chess for Pawn three-step, but it has perfect implementation of modern free castling with the King moving over 2 or more but not past Rook.  Gollon's book has a few dozen CVs exhibited, nothing like the couple thousand of Pritchard 'ECV'  twenty years later.

Aronson calls Complete Permutation Chess more flamboyant 'Tutti-Uti-Frutti Chess' in that one's text, and if I had noticed the above sequence more carefully I would have approved TUF over bland CPC. Complete Permutation adheres to idea of using each possible bi-compound once -- originating in Betza & Cohen.

*Betza's Chessopoly and Race Chess are 64-square 4 x 16.


Regulator Chess. Game on a 35 square board with a 7 square track on which a piece moves that determines how Knights and Bishops can move. (6x7, Cells: 42) [All Comments] [Add Comment or Rating]
George Duke wrote on Tue, May 8, 2018 07:51 PM UTC:Good ★★★★

How to compute piece values here?  It's pointless to bother.  Regulator move one forward or backward is determined by play on the small board of 35 squares.  Too bad no one has experimented with the Regulator band on 8x8 with 7-square streak to the side for neat 71 square Chess Variant, a first for the size.

84-square Fourriere's Jacks and Witches lessens Bishop value to Knight by the 16-square hole in the center -- more detrimental to the Bishop now worth 2.5.   Any different board size must affect piece values somewhat.  A Fischer Random Chess array NBKRRQBN should benefit Rook to relative downgrading of Knight, maybe 5.3-2.7.  But adherents to FRC have not gotten that far yet.  So the starting line-up alone affects piece-values.  Also do the Rules in and of themselves, such as obvious thing like Bishop one-time Wazir step conversion in some CVs. 

Take the simple Regulator embodiment here.  Level 6 of regulator makes Knight into Marshall, and Level 3 makes Bishop into Cardinal.  If the board were 8x8, it's not definite which in a given game benefits more, Bishop or Knight,  because there are going to be enough move- and capture-triggers to jockey the calibration up towards level 7 tactically pretty easily, and keep it there.  Over the long haul however, Bishop value is going to show relative increase, on any rectangle 35 to 100.  That is because of its compound to BN being in effect 5/7 of the time and the other to NR only 2/7 the time.

Next, there is room for subvariants, that either side can alter the calibration, let's say forward by agreed-on even number of steps across 7 and back to 1 and onward, in lieu of a move. That can include in the Regulator Band not just moving the Regulator but either of the two trigger levels the same way, as not overcomplicated move addition.


Choiss. First place your squares, then your pawns, then your pieces, then move.[All Comments] [Add Comment or Rating]
David Cannon wrote on Fri, May 11, 2018 11:39 AM UTC:Excellent ★★★★★

This is very similar to a game that I have conceptualized, but never published. My own game starts with the usual 8x8 square board and the pieces arranged as usual, with all the usual rules of play, except that in lieu of moving a piece, either player may move an unoccupied square. A square may only be removed from the edge of the board (an edge cell being one with less than four orthogonally adjacent cells) and placed orthogonally adjacent to another cell.

I have a (general) rule of not publishing things here until I have programmed them for Zillions. I'm a mediocre programmer at the best of times, and when it comes to creating cells that may be moved by either player, I'm stuck. I've worked out how to make cells that only one player can move, but making them neutral and moveable for both sides is something I've had no success with. 

I've thought of a similar game based on moveable hexagons.


Anyway, I'm glad to see I'm not the only one to have thought of a game with a "dynamic" board.


Orwell Chess. Three player variant themed on George Orwell's 1984. (7x12, Cells: 84) [All Comments] [Add Comment or Rating]
George Duke wrote on Sun, May 27, 2018 07:58 PM UTC:Excellent ★★★★★

J. C. Hallman in 2004 'The Chess Artist' interviews Kirsan Ilyumzhinov at his multi-million Chess City, Kalmykia.  Then the f.i.d.e. President says to the effect:  whatever happens, or even thought of, in the mundane "real world," Chess has already been there, having visited every eventuality.   So this Orwell '1984'  by Overby.

As in '1984', three  players Eurasia, East Asia. and Oceania.  Everyone reviewing loved it except Charles Gilman.  Maybe he is right one or two of the 7 piece-types could be tweaked.  But this is perfectly symmetrical solution to three-player CV.  

Three teams ebb and flow constrained from unfair alliance by cylindrical downwards and up, and by Shifting Alliances rule, and by Perpetual Powers rule.  Variant pieces go back to year 1283 in Gryphon.  King may move into check because the dice may free him.  The '3x1's give where the Berolina pawns promote, and the seventh piece is promotee royal Maharajah.

My rating is specific to the Davidson Variation of Chaturanga.

If Davidson was correct (about Kings being able to move into check and to be captured), this would make an interesting alternative evolution story from Chaturanga to Shatranj, which makes a nicer transition story from Chaturanga to Shatranj to Chess.

Jumping Chess. Pieces capture by jumping. Board has extra edge squares making it 10x10. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
George Duke wrote on Wed, Jun 27, 2018 03:32 PM UTC:Excellent ★★★★★

Jumping Chess originates the edge squares that Rococo uses two years later. Bishop captures like International Draughts diagonally and Rook like Turkish/Israeli draughts orthogonally. Except no plural captures, and in JC the line pieces slide any distance beforehand. But no displacement capture at all here. Jumping concepts are bandied about in 'ECV' a few times, but credit this improvement for the rim accessible only capturing.

JC may create too many defensive positions for most aesthetics.

JC year-2000 date of invention harkens to V. R. Parton's booklet 'My Games for 2000 a.d. and After' published 1972. There the CV "2000 AD" sources pieces for 30 years later great Rococo. Firsthand, Rococo is basically a derivative Ultima (1962).

( Contrariwise, Robert Abbott himself weighed in early Rococo comment that no need for border squares, just get rid of them. ) See next how Rococo draws on both Abbott and Parton. 20th century the chief variantists were Boyer, Parton, Betza and Dawson, but Dawson didn't bother with designing actual CVs.

The Rococo pieces straight out of Abbott's Ultima are Withdrawer, Immobilizer, Long Leaper, Chameleon. And the Rococo pieces straight out of 2000 A. D. are Ximaera and Swapper. Ximaera gets re-named Advancer. Finally, Rococo takes its own inventor's border squares from JC and adds that great novelty Cannon Pawn.

Perimeter-squared JC has little play, but Rococo, when adding its subvariants Push-Pull and Mirror, has the same number 10 rank approximately of near-form Ultima at Game Courier. And several ahead of them are a standard Chess form around hundred(s) years. Or combine play numbers of Ultima and Rococo and they are number 3. So arguably derived-form Rococo is a topmost world-class CV. Thanks to contribution of porous out-migration squares from selfsame JC.

Kevin Pacey wrote on Wed, Jul 25, 2018 06:00 AM UTC:Good ★★★★

I'm not all that sure I agree with (as I noticed elsewhere) Greg's usual dislike of variants having lots of 'power' (in terms to having several very powerful pieces, on a board of relatively modest size dimensions in particular, I assume), but this variant's very powerful armies on an 8x8 board strikes me as very over-powered, at least at first. Still, if Ralph Betza has given his name to a variant he invented, it suggests the idea may not be so bad at all... It's been played lots on Game Courier, so far, so that alone means its had some pretty good testing.

Wow.  I like. 

Bishop moves are darn tricky.  They have an abundance of paths to take, I'm guessing they are valued approxamently the same as a rook.
Also, don't rooks tend to be more dangerous on a circuar board?
Consequently, the queen might be overly powerful.

I honestly think that there could be more peices to play with the different angles.

I think this has a germ of brilliance, but incomplete.  This definitly has some unrealized potential.

Anthony Viens wrote on Fri, Sep 14, 2018 06:42 AM UTC:Excellent ★★★★★

This is one of my favorite variants on the site!  Very well done.  I like the concept of the river as a barrier, but you didn't stop with that as a gimmick.  You also made the piece types work with the river!  There is an archer to shoot over the water, the ram could be too powerful but the river hampers it's deployment, and a catapult to toss pieces....great job.

Now, there are a few things I would do different (imitation being the sincerest form of flattery, I may design a derivative) but there is only one thing I think is not designed very well.

Why do you have 5 ranks on each half of the board?  Xiang Qi also has 5, but the pawns start on the fourth rank.  Catapults of Troy's pawns start on the second rank, and don't have an initial double (or triple) step.  I would venture to say this makes pawn development very very slow.  

Which would be fine, except I see absolutely no benefit from it.  The river already has a huge damper on pawn development/attacks, so even if you wanted to limit pawn interaction in the game it's already redundant.  Not to mention, slowing the game (particularly the opening) down for no actual change doesn't seem like a good idea.
It slows down getting the bridge builder into position, it slows down getting the Trojan Horse into the action...it also makes developing the bishops really awkward....Honestly, it makes everything except the catapult sadly out of position.  I'm afraid the opening of Catapults of Troy would devolve into catapulting most of your pieces close to the river just to save 30 turns of development.
Frankly, I think there is so much empty space eliminating only one rank from each side would still play almost the same.  Slightly shorter opening, sure, but nothing else. 
Again, all this would be OK, except I see no benefit at all.  Just an unnecessarily stretched opening.

Am I missing something?  Please inform me, if so.
(Maybe you like a long opening!  That's OK.)

I would allow pawn double step and eliminate one rank per side, personally.  I think that would speed up the opening tremendously and lose nothing--maybe lower the importance of the Catapult a little bit, but at the moment Catapults look too central to moving pieces.

All that being said, this is STILL an excellent game.   I can handle an unnecessarily long opening, so long as the rest of it is great!  One of the best on the website!


Gross Chess. A big variant with a small learning curve. (12x12, Cells: 144) [All Comments] [Add Comment or Rating]
Greg Strong wrote on Fri, Sep 14, 2018 05:57 PM UTC:Excellent ★★★★★

This is an excellent game. I avoided it for a long time because I thought the large amount of power on the board would make it too difficult for me to deal with. It turns out I find it very playable, although it does require me to spend more time thinking before making a move for most of the game. Midgame positions can be exceptionally complex.

The opening starts out feeling nice and slow, as though the first 10 or so moves don’t matter too much. While I think it’s true that there is a very large amount of flexibility to how you can play the opening, those moves are still very important. At some point, typically around move 20, the game breaks open and becomes tactical and violent quickly. You want your pieces well-positioned when that happens. There is some contention for the e4/e9 and h4/h9 squares. All three of the light leapers – Champion, Wizard, and Knight – are good to develop early and all three are natural to develop to those squares, so you must choose which to develop there. I find that typically one of these three piece types doesn’t get developed in the opening before the game gets wild. I think it’s important to get the Vaos developed early. By the endgame, they are the weakest piece, but their low material value and ability to make long-range jumps gives them significant power to harass the heavier pieces as the game progresses. Developing the Vaos generally requires developing the Knights.

I like the promotion rules overall but the 14 extra pieces each player starts with in reserve seem unnecessary. There is tremendous carnage before any pawns are in a position to promote so lack of replacements is not an issue. The extra Queens are the only pieces that have any realistic possibility of being used.

Well-played games are typically nail-biters and the dynamic between the two players can reverse several times before it’s over. Having the momentum is very important – you want to be the one forcing the opponent to react, and the longer you can keep it that way, the more advantage you will accumulate.

My estimage of the piece values:

Piece Ave. Dir. Attacked Ave. Safe Checks Ave. Mobility Midgame Value Endgame Value
Queen 7.03 29.03 17.33 12.5 13.5
Marshall 9.78 24.44 15.79 10 11

It truly is amazing how many exquisitely different and unique Chess variants have been invented.

I personally always prefer something more closely resembling the Classical concept, for example Modern Chess and so forth, but am astounded by the dedication given by people like yourself to the intricate details of playability, in what would seem an almost bizarre game in comparison.

Well done!

It's just brilliant! I had an idea once for a piece called "The Lovers". It was basically a figurine of a man and woman holding each other, but which could separate and thus have two pieces distributed about instead.

"Catapults Of Troy" reminds me of this, specifically the Trojan Horse, with its ability to deploy Archers.

Whilst this game is not Classically orientated, there are good things to come from designing pieces such as these, which are two abilities combined as one.

Nice work. ;)

Other than just being chess on a triangular board, this looks perfectly playable!  Very nice!

I don't find any information about Pawn promotion in Wormhole Chess. Do Pawns promote on the last square they can reach, whatever the rank (for example if there are no squares anymore vertically in front of the Pawn, beyond the wormhole, nor diagonally where an opponent's piece could land)? Or do they only on the last rank, meaning that if a Pawn can't reach the 8th rank anymore, because of the disappearing of squares, he can't promote anymore?

This comment gives me the opportunity to rate this game as 'excellent'. Really great concept and gameplay. It would be great to have a larger variant of Wormhole Chess, 10x10 or even 12x12.

I strongly encourage continuing work on this....I love the idea of 'choosing different armies'!

Sirlin's Chess2

Betza's Chess with Different Armies

Fantasy Grand Chess

And your idea of a one-time enhancement Trance (spell) appears to be an excellent idea of something different while not being too powerful.

However, I think the rules need some clarification.
In particular, the army 'Hologram' appears underpowered rules-as-written.  You gain the ability to suicide your queen to teleport your king.  Useful, but only so much.  You can't use it offensively (teleporting your king to the front lines is not smart) and if you use it to get the king out of check you're already in a bad way, and probably only delaying the inevitable.
Meanwhile, you loose the ability for the queen to capture--but it can still be captured, apparently.  So the queen is essentally useless.  (The rules specify only that the queen cannot capture.  All other rules being the same as chess, that means the queen can be captured.  A queen that cannot capture or be captured is useful as a blocking piece--is that what you meant?) 
The Trance is not that powerful, only allowing the queen the ability to capture kingwise.  (If the queen is uncapturable, this is very powerful.)
I'm left with the conclusion that you must have meant the queen cannot capture or be captured.


Chess 2. Different armies, a new winning condition, and duels. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Anthony Viens wrote on Mon, Nov 19, 2018 03:17 AM UTC:Average ★★★

I've played a fair bit of Sirlin's Chess2, so I'm going to make a bunch of posts to move the rules onto CV website, in case the game is ever abandoned by Sirlin games.  I will also comment on the game in general.
Sirlin's Chess2 is quite balanced, and has clearly gone through a lot of playtesting.  Being developed by a modern boardgame company owner clearly shows here!

First, Sirlin's Chess2 adds 3 things:

1)win by centerline invasion
2)dueling stones; possible loss of an attacking piece
3)different armies.

Quote from offical rules:

New Win Condition: Midline Invasion
You can still win by checkmate, but you also win if your king crosses the midline of the board. Each move has added significance, because you must weigh how much it helps or hurts each player’s chances of winning by king crossing the midline in addition to the usual considerations of furthering a checkmate.
Just like in Chess 1, it’s illegal to move into check, so to win by Midline Invasion, your King must land on the 5th rank without being in check. Unlike Chess 1 though, there are no stalemates. If you have no legal moves, you lose the game.  While stalemates are common in Chess 1, they aren’t needed in Chess 2 because the Midline Invasion rule provides an even stronger option that a player can aim for when he’s down on material.


In practice, against reasonablely competent players, the majority of games will end by midline invasion.  For one thing, whoever is winning can typically move his king up before he checkmate's his opponent.  The big change, however, is when a player starts to loose, he will usually make a quick attempt at midline invasion win.  This makes the transition between the mid- and end-game very chaotic.
Most non-chess boardgame players will find this a very exciting change; instead of a long slow grind as one player increases his advantage, the the game ends in an explosion of desperate dashes-for-the-midline.  While the player who is in a better position will still usually win, there is more hope for the loosing player.  Having more on the line, it is more exciting for both players, despite the fact that the game still usually ends as expected.
This also esentially eliminates the chess endgame--which most casual players consider the most boring.  Once a player has a significant advantage, chess tends to grind toward an inevitable conclusion.  This is why experienced chess players will conceed when the game gets past a certain point--going through the motions is just a waste of time.
As a side affect, Sirlin's Chess2 games tend to be shorter.  Modern boardgames (not chess variants) tend toward shorter is better, so non-chess enthusasts would generally consider this a good thing.

This is where Sirlin's modern boardgaming design experience is showing....he has designed a change that appeals to the masses (more exciting desperate chance of a win) and eliminated the masses least favorite part of chess (the grinding endgame) and shortened the game in one simple rule.

There is just one problem.
MOST CHESS PLAYERS DON'T LIKE IT.
I don't like it either!!!
Effectively getting rid of checkmate just feels WRONG.

Sum it up=theoretically a good change that appeals to casual players, but chess enthusists won't like it at all.

 

Dueling
Quote from offical rulebook:

Dueling

Dueling allows you to spend a new resource called stones to threaten to destroy a piece that takes one of your pieces. Try to trick the opponent into wasting his stones because if he runs out first, you automatically win any further duels.

You start with 3 stones and gain 1 stone each time you capture an enemy pawn, up to a maximum of 6 stones.

Whenever you would capture any piece, the defender can initiate a duel. If your piece is higher rank than his (ranks: pawn -> knight/bishop -> rook -> queen), he must pay 1 stone to initiate a duel. To duel, you each put 0, 1, or 2 stones in your closed fists, then simultaneously reveal them. All stones revealed are destroyed. The winner of the duel is the one who showed more stones--ties go to the attacker.

If the attacker wins a duel, he takes the piece in question as in normal Chess. If the defender wins, he still loses his piece, but the attacker ALSO loses the piece he attacked with.

Initiating a duel and bidding 0 is a bluff to make the opponent waste stones. The attacker calls your bluff by bidding 0 himself. He wins because attacker always wins on a tie and in addition, the attacker can choose to gain 1 stone or cause the defender to lose 1 stone. (A player can't have more than 6 stones.)

Kings cannot be involved in duels because they have "Diplomatic Immunity." (They can't initiate a duel or be dueled.)

Players with 0 stones cannot initiate duels, but they can be dueled against. When you duel against a player with 0 stones, you must bid 1 and you automatically win the duel. If you lose a pawn in a duel, your opponent does gain a stone.

 

Dueling is another change designed to switch the game up.  Normal chess has a very mathmatical quality to it--good players can predict moves very far in advance.  The farther forward you can think, the bigger your advantage.

Dueling changes this.  Now, sometimes you won't keep a victorious piece.  Consequently, there is only so far out it is practical to predict moves, leveling the playing field a little bit.
Dueling accomplishes this WITHOUT resorting to chance.  The number of stones each player has is public knowledge, and he who correctly reads the importance of the current board position and his opponent will win the duel.  (And the attacker has the advantage, so ties in skill will result in the same board state as if no duel occured.)  However, this requires a very different set of skills than chess.

Consequently, it is possible for someone who is really really good at typical chess to be beaten by a player who is better at reading his opponent and bidding accordingly.  Someone who is bad at bidding may be winning--until they run out of stones.  This gives the othe player a big advantage.

By broadening the useful/necessary skills to win AND lowering the ability to look ahead, a larger variety of player types can be effective players.  Plus each duel is a mini-game, which gives flashes of excitement in the middle of the game.

Again, Sirlin's skill at designing modern boardgames shows.  This is a rule that should appeal to the masses and create some excitement, while lowering the necessity of mapping out future moves.

There is just one problem.
MOST CHESS PLAYERS DON'T LIKE IT.
I don't like it either!!!
Effectively making it uncertain if you are keeping a piece just feels WRONG.

Sum it up=theoretically a good change that appeals to casual players, but chess enthusists won't like it at all.

Truly beautiful concept, and it appears to work.  (I have not had an opportunity to try it myself, yet.)

Reading through the comments, much of the complaints seem to focus on the power of the knightrider's ability to reach the back row and promote.  I wonder if anyone has considered that the knightrider move and the promotion rules may not work together perfectly?  Changing them would result in a different game, but possibly a better one.  Just a thought.

This is a very nice-playing modest variant. I've greatly enjoyed my games of it. I can absolutely recommend this game as an excellent variant tournament choice. It gets a lot of mileage out of a pair of fairly simple changes. The initial set-up is excellent; it gives good play. The weak piece is a very nice choice, and provides a nice companion/foil for the bishop and knight.

SL Reed wrote on Thu, Dec 27, 2018 08:55 PM UTC:Good ★★★★

I just began play-testing and I like it a lot.  My thoughts so far:

There is a tiny bit of ambiguity as to whether the “same file rule” from Shogi is meant to apply to pawn drops (presumably it is not). I believe it can be played either way. I haven't tested it yet, but to try, the following condition could apply:

A pawn may not be dropped onto the same vertical diagonal of any other non-promoted pawn belonging to the same player.

Or an even stricter alternative:

A pawn may not be dropped onto the same rank or file of any other non-promoted pawn belonging to the same player.

In the illustrations for piece movement, notice how the rook travels through one edge and then through the opposite edge of each square in its path (even if the 'square' curves a right angle), while the bishop travels through one corner and then through the opposite corner of each square in its path, but seems to be prohibited from doing so on the curved squares (from the black bishop's position in the diagram). If this prohibition were lifted, that same black bishop's range of movement would include traveling from one curved edge square to the next and then back across the board horizontally, forming a loop back to it's original position.

Also, although it is not explicitly mentioned in the original rules, I think it's probably a good idea to declare that a rook or  a queen (or a bishop) may not land on the square from which they originated on that turn, even if a path to it exists unobstructed.

Finally, my thoughts about the pawn. The language and illustration of the original rules regarding pawn movement suggests that pawns capturing moves and non-capturing moves are executed in the same way (unlike conventional chess). Optionally, one could alter the rules for pawn movement so that it moves (but does not capture) exactly one square in either of the orthogonal directions that is away from its own side of the playing board or it can capture to the cell diagonally ahead of it (if there is an enemy piece occupying that square).

I just made my copy of the board yesterday, and have only had the opportunity to play-test the original rules.  But yeah, it was a lot of fun!  Thanks!

Erik Lerouge wrote on Sat, Aug 10, 2019 08:31 PM UTC:Excellent ★★★★★

I am currently playing a game of Odin's Rune Chess, and I really like it, as much the rules and gameplay, as the runic theme. The Forest Ox is a terrific piece, maybe too powerful... I like the rather strong Pawns. I generally appreciate modern variants that use non-conventional Pawns, it effectively renews the dynamics of a chess game. And their initial colorboundness isn't a default at all, for me.

I was wondering if Pawn promotion could be integrated in this game - even if it is not necessary since Pawns can go back and the need for new material is less crucial, since the vulnerabiliy of the Kings without moving possibilities makes situations of insufficent material less likely. Promotion possibilities should be limited, since Pawns can reach the last rank in only four moves; for example, they could only promote to previously captured pieces of his own colour; or there could be limitations to the maximum number of pieces of each type present on the board (4 Valkyries, and 4 Forest Oxen, for example - which is already a lot). One can also think of the opportunity to permit the promotion to King (here too, the maximum number must be limited or promotion be only to previously captured Kings). But the game plays already well, I don't think it needs a promotion rule. I was just wondering how promotion could affect the gameplay, and if it could be interessant as a variant.

Edit: my comment about the possibility of promotion wasn't very pertinent. Promotion doesn't make much sense in this game.

Musketeer Chess. Adding 2 newly designed extra pieces. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
💡📝Zied Haddad wrote on Tue, Aug 27, 2019 09:57 AM UTC:Good ★★★★

Hi, it's always good to hear criticism. And i think you've got it right.

Personally i give you the pieces i much like when playing Musketeer Chess: Hawk, Unicorn +++ and my favorite is the Archbishop combining Bishop and Knight abilities. I much like sacrificing my Queen for an Archbishop !!

 

Musketeer Chess idea was to get rid of the big amount of draws and also opening learning (long theoretical lines). The idea is also to give black a more important role by deciding the final combination of pieces, adapting his strategy to white's choice which will lower for sure the importance of white's advantage as the side who begins the game; But this needs for sure a precise play.

 

You pointed out the fact that the Board is overcrowded. Of course it becomes a problem if you choose to gate you r pieces whithout a prior clear strategy and this will hamper you from exploiting the huge potential of the new pieces.

 

The newly added pieces are strong and they bring so much excitment and tactics from the first move ! So the slightest lack of attention can be punished (more spectacular wins) but also if you lower your attention even with a huge material advantage on the board, your opponent can surprise you and mate you using the newest pieces whom some can mate alone.

 

Yes, Musketeer Chess is not a perfect game, but Classic Chess became mostly a game of "knowledge" and opening learning and is for sure less attractive for average kids and players that want to improve their level but are frustrated by this learning.

Elite tournaments are less spectacular and games most usually finish with draws.

Kevin Pacey wrote on Sat, Dec 14, 2019 06:06 AM UTC:Good ★★★★

Below is a link to a site apparently written by the inventor of Grand Chess (and other variants); in it's coverage of that variant, it mentions that the inventor strove for 'completeness' (by adding the Archbishop and Chancellor piece types that he felt were missing from FIDE chess) - similar to the inventor of Amazon Grand Chess, I kind of feel logical completeness might mean including an amazon piece for each side (possibly the inventor of Grand Chess rejected this simply due to having an odd number of pieces in each army as a result). Note in my 10x10 variant Sac Chess, which has had a lot of testing, having 2 amazons per side (though on a crowded board initially) doesn't seem to hurt the quality of the play in games much at all.

Anyway, for a variant idea I'm still considering, I came up with an alternative setup to that of Amazon Grand Chess (I thought reverse symmetry for the setup can be used, to make the odd number of pieces per side seem less asymmetrical, IMO). On a seperate website from the one below I saw some posters wishing that Grand Chess used normal promotion rules, as in chess (so that the board's edge is made use of for one thing), and also that it allowed a king to leap up to 3 squares once per game, to make up for the absence of castling, so I'm considering these as possible refinements, too. I'll also mention that one thing I don't quite like about the Amazon Grand Chess setup is that the amazon and queen of each side are doubled on a file (albeit behind a pawn) before play even begins... Now, here's the link I mentioned:

[edit: Here's a link to a discussion I alluded to, about how Grand Chess might be improved:]

https://en.wikipedia.org/wiki/Talk%3AGrand_chess

[edit2: Here's a diagram of a CV idea of mine that might be called Grandiose Chess, which I'll study at leisure (pawns would promote on last rank to any piece type in the setup, except for a king, and an unmoved king that's not in check can leap up to three squares away to an unoccupied square on the first or second rank that's not under attack, regardless of any pieces or enemy attacks that may be in between):][edit3: I'm not liking this so much just now - perhaps it's a worse version of Grand Chess, or even of my own Sac Chess:]

Grand Chess is built upon two main ideas; getting rid of castling by freeing the Rooks in the back rank, and introducing the two 'missing' compounds to be additional high-value pieces--the Cardinal & Marshall.

Euchess moves the Rooks back and re-introduces castling, and then doubles the number of Cardinals & Marshalls--but, inconsistently, keeps one Queen.

Ignoring the lack of numerical consistency, this is really bad from a playable perspective--the sheer number of power pieces diminished the value of Knights & Bishops significantly.

Euchess is much too top-heavy, power wise, and significantly dimishes the point of the open back row. (Marshalls, with their Knight move, don't need the room to be developed.)

I think there is room for some interesting variants of Grand Chess, but this isn't one of them.

This is a really good idea, the only problem being it really needs a custom Chess set.

I'm guessing it would require similar bluffing strategy like Stratego. I can see myself thinking "hummm, that faux Pawn can't be anything valuable, it's too exposed.... unless that's what he wants me to think....or, he could be counting on me to think that's what he wants me to think...."

:-)

This actually has a decent chance of commercial success, in my opinion. It's got 'wow' factor, but close enough to normal Chess to feel familiar.

Great idea.


Xhess. Decimal variant with Nightriders and Cannons. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
Anthony Viens wrote on Thu, Mar 5, 2020 01:03 AM UTC:Average ★★★

This looks like a decent 10x10 variant; it has the basic Chess pieces--with more mobile Pawns-- and well-known Knightriders & XiangQi Cannons.

The King game-winning 'promotion' rule could liven up the endgames without totally changing the game.

However, I am confused as to the logic behind the apparently abitrary initial setup. The Rooks have an open rank (like Grand Chess) which is fine.  But the Horsemen (modified Pawns) are more mobile--but start very close to each other.  So close, in fact, they can't use their forward most moves initially without being captured.   Except the Horsemen on the far ends; they start one rank farther back for no discernable reason. 

The forward pawn lines leave a bunch of space to the rear; considering the vast area there aren't very many other pieces.

Also, the Knights are back a rank from the Horsemen, consequently they cannot move forward as the first move. They are protecting Horsemen, but it seems like there ought to be another way to do this.

Xhess is quite playable, but I'm left with the impression the starting setup could use an overhaul.

Very good, well-thought out game, with pieces which compliment the board--some require elevator movement, some use the empty shafts, and the ox can use them to capture. Nicely done.

I will say the rules allowing the flying pieces to go 'up, through an elevator trapdoor' feel very unintuitive; especially if playing with a physical set. It makes more sense to me to allow flying pieces to go either up or down through the empty shafts only; this would also make it impossible to threaten an identical piece without also being in danger.

Still, a very good variant!

I can't believe this game hasn't been reviewed yet. This is the best game I've played that includes an Amazon. I normally leave the Amazon out of my games, because it has the power to force checkmate by itself, and that has the potential to wreak a game. However, that hasn't been a problem with this game. This game includes several other weaker compound pieces that help make it unsafe to move the Amazons out too early. To get to the point where you could use an Amazon to force checkmate against a King, you have to do lots of maneuvering of other pieces. Furthermore, the potential of the Amazon getting a bead on the King means that position is sometimes more important than material advantage. You can't count on winning just because you are ahead materially. If you find that you can't stop your opponent's Amazon, you may lose even if you're materially ahead. This makes the game more dynamic and exciting.

I don't usually like games with different armies, but this is an exception. You've put a lot of thought into making a game whose different armies are not unevenly matched. For sure, the Spartan side lacks a Queen and its army appears to be slightly less powerful, but that is compensated for by the presence of two kings, both of which must be checkmated/captured.

I think this game is OK, but I do not care for the promotion rules.  The game does not have a queen, so promotion to queen would already be the strongest piece.  The amazon seems excessive and most games that feature that piece are not very good IMO.  The amazon attacks in 16 directions while the next strongest piece - the rook - only attacks four.

Pieces are never attacking friendly pieces or I miss something

That is the answer to my question. So if a virgin King is on h1, a black Bishop on h2, and a black Knight on g4, the King can move to h3. If his own Bishop was on h2 instead, he could not.

Some people would say pieces can attack the square a friendly piece is on. They obviously cannot capture it, but that doesn't necessarily mean the same thing as being attacked. E.g. when my King stands next to an enemy Pawn that is protected, does he attack that Pawn?

Personally this rule strikes me as quite illogical; to pass through a square it should be empty, and if you don't pass through it but jump over it, you shouldn't have to worry if you are attacked there. And I wonder how much this rule actually affects the game; it seems very hard to attack any squares next to the enemy King before he moves away to safety, as he starts buried behind 2 or 3 ranks of pieces. Especially if he can jump.

In general I like your variants a lot, because you do not only feature super-strong pieces (much stronger that Rook), but also Knight-class pieces. Most variants suffer from an over-abudance of Queen-class pieces. The middle of the strength spectrum is still a bit under-populated, though: almost none of the pieces is close to a Rook in value.

Great idea. I have always loved Fischerrandom Chess, but I really don't like the way it gives players no control over where their pieces start. I also consider Fischer's castling rule to be cludgy and it's hard to believe that a man of his genius came up with that. Your project fixes those shortcomings. 

One tweak I'd make if it were up to me is to require both players to enter ALL their pieces before making any other moves. White would enter a piece, followed by black, and they'd take it in turns to enter pieces, one at a time, until the first and eighth ranks were full. Of course, Bishops must be required to be on different coloured squares.

Jean-Louis Cazaux wrote on Wed, Jul 1, 2020 08:34 PM UTC:Good ★★★★

I have 2 questions about the brouhaha squares:

1) What is the advantage of allowing a capture on a brouhaha square? Spontaneously, I find this strange: I understood that such a square hosts a piece until it is activated and enter into play, then the square disapears. Then, this square is not part of the play area really. So, I wouldn't have allowed a capture on it at all. Maybe there is something I don't see.

2) Why this name of "brouhaha" square? At least in French a brouhaha is a surrounding noise. Those squares are more like a fog, brouillard in French. Brouhaha/brouillard, is there a linguistic confusion there?

This is an excellent chess variant, and is one of my favorites. I think it plays better than either of the games from which it is derived. The starting position is carefully considered, allowing a wide variety of different openings.

The rook should still be worth slightly more than the bishop on this board but it is very close. I performed the mobility calculation. With a 30% board occcupancy, the rook's average mobility is 9.8 whereas the bishop's is 9.2. And the mobility of the rook increases faster than that of the bishop as the board clears out.

The design of this game makes no sense to me. The Rook is upgraded to a Dragon King. The Knight is upgraded all the way to an Amazon. The Queen is upgraded to the most powerful piece I have ever heard of. But the poor Bishop is downgraded to a Wazir - a piece that moves only one step horizontally or vertically. One problem is that the board has so much power that it will be a tactical smash-fest. Another problem is that the Wazirs will never move. I cannot imagine any circumstance in which a player would waste a move on them, except possibly to get them out of the way to allow castling, and probably not even then. With all the nightriders, castling will likely be impossible anyway.

I once had a CV of my invention (Wide Chess) gently criticized for my adding to the standard chess army of each side (on a 12x8 board) 4 pawns, plus two pairs of leapers that were somewhat similar to each other, in that they both had an alfil movement as part of their powers. Namely, it was thought said leapers weren't divergent enough from each other.

In the case of (10x8) Royal Court, a pair of leapers plus 2 pawns is added to the army of each side. The leapers have the same movement powers as knights, plus they can also move like a man (often called the Centaur compound). So, I can see how this addition of leapers to the standard chess army might be gently criticized, too (at least they are very powerful leapers, which might relieve any perception of slight redundancy).

Recently I had a couple of ideas of my own about adding pair(s) of fairly knight-like minor pieces to the FIDE army, although I may have rejected these ideas too quickly, partly due to the previous critique (of my Wide Chess). Namely the ideas involved adding either a pair of fibnifs and/or a pair of horse(mao)-wazir compound pieces (depending on the board size I would use). Besides Wide Chess not yet proving popular on Game Courier, I'd add another inhibition I have is that I've seen very few examples on this website of the FIDE army plus pair(s) of pieces added to them, where the pair(s) were not strikingly divergent in some way from other piece type(s) used in the chosen armies. Indeed, Wide Chess and Royal Court are more or less the only counter-examples I've noticed.

4 Kings Quasi-Shatranj. Each side has 4 Kings, all pieces are short range. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
Erik Lerouge wrote on Sun, Dec 13, 2020 10:49 PM UTC:Good ★★★★

I like very much short-ranges games, even with not very strong pieces, and this game falls into this category. Here the piece set (only of max 2-square range) is logical and works well, and the presence of 4 Kings, of which one must be checkmated (with the consequence of a unstoppable fork on several Kings being a checkmate), is here to help the outcome of the game. However, even with the 4 Kings, the game seems to take a very long time to finish; the two games in this website that had been led to a conclusion took 85 and (for the game that ended with checkmate) more than 110 turns, which seems too much for a game of that type. And I am a little bit sceptical concerning the mating potential: when most pieces have been exchanged, the four Kings can more easily prevent the Pawns to promote.

One solution would have been stronger 2-square range pieces, in a game closer to a short-range version of Sac Chess, with a KNAD being the strongest piece (or at least Centaurs, or KADs). The presence of the KNAD, able to force checkmate without assistance, would obviously make the game faster and more decisive, but in the same time maybe less balanced and tactically interesting. (In Metamachy, the power of the KNAD/Lion is well balanced by powerful long-range pieces.) And I wouldn’t suggest a change in the piece set of this game; it works well as it is, and a like it.

Another idea is making a game with 2 moves per turn. With the same pieces and victory condition, not only this would make the game shorter, but also the attacks more dangerous and less easy to counter (and the possibility of double check with two pieces). This solution seems to me more interesting, while keeping the character and the concept of the game, than to have stronger pieces.

This is a very good game. Everything fits together well. The random setup provides variety without being completely chaotic. The brouhaha squares are a great way to add more pieces without making the board so big it feels empty. The promotion rule encourages more variety in promotion, which is something I look for particularly; and I like the auxiliary pieces used here. The Mameluk especially is fun.

I think I might slightly prefer the Modern Apothecary game, for it's Dragon and Griffin, which to me are more interesting than the Chancellor and Archbishop, but I like the Siege Elephant and Mameluk as auxiliaries, so it's hard to choose one game over the other. I don't know if I'd agree with the statement that the Joker can't defend well. It seems to me that it's ability to mimic an attacker's move makes it particularly good at defending and more difficult to use aggressively. I'm not great at chess (in any form), though, so I could be wrong about that.

I'm interested to see what the next games in this series will be like!
