'Pawn promotion can only happen on back hexagons previously occupied by opposing forces.'
So, if they get to the end of file a or l (in the 2 player game) they have to wait until there's an enemy to capture to get them somewhere where they can be promoted? This is a major departure from square-cell and even other hex variants. For myself I consider McCooey's game a greater improvement on Glinsky's, and suspect that others will agree.

Magic River. Xiang Qi pieces crossing the Magic River turn into their Western counterparts, and vice versa! (17x9, Cells: 77) [All Comments] [Add Comment or Rating]
Charles Gilman wrote on Wed, May 13, 2009 02:28 AM EDT:
A possible solution has occurred to me to the complications of certain Xiang Qi pieces being restricted or having no FIDE Chess counterpart:
	The Elephant is barred from entering enemy territory, but its positional counterpart the Bishop is not, leaving it turning into an Elephant that shouldn't be there. On the other hand the Cannon can enter enemy territory but, in your variant, has no counterpart to become when it gets there. How about making the Bishop transform to a Cannon and vice versa? That way both pieces can continue in a relatively normal way. This also echoes the Bishop's position in Shogi, which could be considered equivalent to one of the Cannons.
	The King and Queen can enter enemy territory, but the reason why the General and Ferz cannot is that the Fortress bars them getting anywhere near it. This could be seen as the Fortress being the real barrier for them, in which case the King and Queen should transform to a General and Ferz unable to enter the Fortress. As they therefore cannot give check they are sufficiently weak pieces to not upset the balance.
	I hope that these ideas go some way to propelling this variant toward excellence.

Approximately 37 or 53 degrees, actually. The directions of the Knight are at 45 degrees to those of the Camel, not to each other. Likewise its compounds.

Further to my last adjustment I have also clarified what I understand to be the reason behind the term 'orthogonal'. I have also moved the definitions of the basic types of radial direction to the introduction, to mark them out from the definitions of individual pieces.

💡📝Charles Gilman wrote on Sat, Jun 13, 2009 01:53 AM EDT:
While pieces may be bound to one of any number of mutually exclusive sets of cells, switching is always between two such sets - in the case of ranks, odd and even. The Bishop can move from odd to odd or even to even rank, as well as between the two, and so is not switching. Pieces that can move within a rank certainly do not switch ranks - although some like the Wazir switch other things. The pieces that always switch rank and file in 2d are the Ferz here, the Camel (and everything else -mel) in MAB 03, and the Bear in MAB 06 - pieces which always move an odd number of both. On a cubic board this is no longer the case as they can move within a rank.
	The matter of this page's compound pieces being unbound on a cubic board I hsve covered. The Primate, Pope, Besieger, and Usurper all have a Wazir move and so are clearly unbound. The Moderator and Heretic are unbound because they can move to an adjacent cell in two moves - by making a 1:1:1 move but retracting it in only two dimensions.
	All geometries' nonstandard diagonals have steps of length root-3 - the description asserting their common identity amounts to a root-2 and root-1 step at right angles.

💡📝Charles Gilman wrote on Sun, Jun 14, 2009 02:33 AM EDT:
Later articles cover other compounds. MAB 04 covers compounds of a symmetric and a forward-only MAB 01 piece in different kinds of directions - all are unbound on a cubic board. MAB 08 covers compounds of a radial and oblique piece - Bishop+Camel=Caliph and Unicorn+Elf=Leprechaun retain their components' bindings but Bishop+Elf=Levite and Unicorn+Camel=Cafila are unbound.

Is there a special name for the Knight in this game? It is not in any of the other historic Shogi variants, but is in several of my own and I'd like to mention the Japanese name (both phonetic and translated) in brackets as I do with the King, Rook, Bishop, et cetera. In return I have some guidance on the English name - the misspelling 'Kinght' is very distracting because it begins with the name of a very different piece!

Charles Gilman wrote on Wed, Jun 17, 2009 03:28 AM EDT:Good ★★★★
As this article covers all three types of mimic concerned in a question of mine that I posted under Joker (and got no answer) I'll post it again here. A Joker imitates the last piece moved - but using its own player's sense of 'forward' where applicable. If the last piece moved was another imitating piece, the Joker imitates the piece that that piece was imitating - in the case of another Joker, the piece that moved before that. Now, what if the last move was a noncapturing move one step forward by an Orphan threatened by - or a Friend protected by - a Queen, Rook, and Pawn? Who decides which 'normal' piece is being imitated?

'We figure the zero(0) squares of Rook either way within one quadrant (the Rook is the border) as coprime for convenience.' Far from it, as MAB 06 confirms. Just as 1 being the only self-coprime number renders the Elephant, Tripper, Commuter &c non-coprime pieces, 1 being the only number coprime with 0 renders the Dabbaba, Trebuchet, Cobbler &c non-coprime pieces. 'So, within 13x13 we are only omitting, with the order mattering,' and regarding 0:0 as already occupied: 0:2, 0:3, 0:4, 0:5, 0:6, 2:0, 2:2, 2:4, 2:6, 3:0, 3:3, 3:6, 4:0, 4:2, 4:4, 4:6, 5:0, 5:5, 6:0, 6:2, 6:3, 6:4, 6:6. The comment '(he is not likely to proceed beyond 15- or 17-block)' at least is true, as I only went as far as I did in response to interest in such pieces in this article's previous incarnation.

While my names cover everything out to max coordinate 9, my coverage beyond that to 13 is fairly patchy. I can identify 10:2 Zrene, 10:4 Sharolais, 10:6 Grine, 10:8 Rherolais, 11:1 Pamel, 11:3 Bemel, 11:5 Humel, 11:7 Lamel, 12:2 Pharolais. 12:3 Ghimois, 12:5 Zoetrope, 12:8 Zeltrap, 12:9 Nhamois, 12:10 Rherolais, 13:1 Cumel, 13:3 Gamel, 13:5 Tomel. Colourswitching pieces to fill just that in would require 12 distinct starting letter pairs - for 10:1/11:9, 10:3/13:7, 10:7, 10:9, 11:2/13:9, 11:4, 11:6, 11:8, 11:10, 12:1/13:11, 12:7, and 12:11. Going out to 15 would require further ones. There are a few pairs left - bo by ce cy fy gy hi ho hy ja je ji jo ju jy ly ma mu my qu ri ru sy ti tu ty vi vu vy wa wu wy xa xo xu xy za zi zu zy - but few are promising and I welcome suggestions. Best to avoid tu on account of its rude Bishop compound. Nor can I see how to continue the sequences ending in Albatross and Deacon. Then names with a C and A would need devising for 10:5, 12:4, 12:6, 14:7, and 15:5 leapers. Is it all worth it for pieces that would be very weak even on a 16x16 board? Personally I doubt it, but again suggestions are welcome.

I have now extended what I now realise was an unnecessarily small range of 2d MAB 14 leapers to larger coordinate 7, using up Ho- and Mu- among the prefixes available. I have decided to rethink 10:n leapers' names as it has dawned on me that they share their SOLLs with 8:6:n ones and that would add a whole tranche of extra new names if I allowed reversibility without duplication. Names ending in -er are of course unsuitable for this because of the Rector, likewise -ry hecause of the existing Rytas. Some of these might be reused elsewhere.

You've got some interesting ideas there. What would a Planar Hopping move be like - requiring exactly one intervening piece on every route? You could end up with a Planar version of Optima or Toccata, with lots of pieces making the same basic Planar move but different details.

Well, an extra rank might help but it would violate the conditions of the competition! You could be right about a second-move advantage, but remember that all possible Princelings are never the whole lot. Remember that they cannot use the triaxial diagonals. So Princelings can be threatened non-mutually by pieces with a forward moves in those directions. Things may turn on which one White chooses to move first and how that affects how well non-mutual threats can be delivered.

Well, I've done all that - in my piece article MAB 13: Straight and Crooked Moving.

It has just occurred to me that strengthened-FIDE-array variants, such as this one and my own recent Overkill Chess and Quadripunch Chess, are particularly suited to combining with my Nearlydouble concept, so that the stronger pieces have a larger board to make better use of their greater powers. Would you be happy for me to include a properly-attributed Nearlydouble Tripunch Chess among a page of such variants?

Charles Gilman wrote on Wed, Aug 5, 2009 03:22 AM EDT:
It occurs to me that a 3-player Besiege Chess with equal armies could very easily be achieved on a suitably adjusted board. One would be to have three FIDE arrays stuck together - Red v Yellow, Red v Blue, and Yellow v Blue, say, with one put in the middle and its camps joined to the same-colour ones on the other boards, and one King turned to a Queen for each player. If this looks too grotesquely large, another possibility is to join two boards but remove the file a/b/g/h squares from the middle 4 ranks. In the latter case I would recommend the middle army having the first move to make up for being attacked on two fronts by two armies each internally united.

Hex Dragonal Chess. Based on an idea by Jeremy Good this CV has horizontal rows of hexes and an unusual set of directions,. (13x13, Cells: 127) [All Comments] [Add Comment or Rating]
Charles Gilman wrote on Thu, Aug 6, 2009 01:59 PM EDT:
I recognise the piece called a 'Rook' here. The idea of a piece moving straight forward/backward/sideways on a hex board was put to me when I claimed that there was 'no piece bound to half a hex board' although the Dabbaba is bound to a quarter of it. I eventually documented it in my piece article Man and Beast 12: Alternative Fronts - you can find it by searching on that page for Moorhen. It is defined by the straightness of the directions (and of up and down on a hex-prism 3d board) regardless of whether they are orthogonal or hex diagonal and whether the orientation is Wellisch, Glinsky, or hex-ranked.

The labels for the directions are somewhat confusing as 'oblique' usually indicates a direction such as that of the FIDE Knight, going through intervening cells off-centredly. A more accurate description for the directions of each colour are forward/backward hex-diagonal, sideways orthogonal, forward/backward orthogonal, and sideways hex-diagonal. The linepieces in these directions I term Unicoranker, Rookfiler, Rookranker, and Unicofiler. These definitions also work on a Glinsky board, but on that it is the first two that have four directions and the second two only two.

Hugo is wrong. It is true that any piece moving to threaten an Orphan is automatically threatened by it, but what if the piece is also protected by an ally? Then if the Orphan captures it the Orphan itself can be captured as it has no time to capture the next piece. For example, there is a Black Orphan on a4 and a White Rook moves to d4, where a Bishop on b2 protects it. If the Orphan captures the Rook, the Bishop can capture the Orphan.
	Is this a record for the time taken to reply to a comment? My excuse is that I have only recently become interested in pieces which imitate.

Fair enough, I could have added losing by losing all pieces (Draughts) or being bankrupted (Monopoly) or being beaten to the last square (Snakes and Ladders) or indeed by being timed out in any game. The point is, the odds of the same player losing by such normal means in two games at once will be rare. What if a particular player is on the verge of winning one game when they lose the other? It could be because (in the case of Chess) they play much better as White than as Black, or because they play better than one opponent but worst than the other, or for other reasons I haven't thought of.

Xiang Hex. Missing description (9x7, Cells: 79) [All Comments] [Add Comment or Rating]
Charles Gilman wrote on Tue, Sep 15, 2009 01:50 AM EDT:BelowAverage ★★
Fergus Duniho's comments have emboldened me to say that I share his reservations but more forcefully. It is well worth taking heed of his expertise on both East Asian and hex variants, as you will see I have done. Had this been the first attempt by anyone at a hex analogue to Xiang Qi I would look more kindly on it, but there is already a history of variants combining these two elements and this one really adds nothing constructive to these earlier variants. The hex diagonal really is too different from the square-board one to suit pieces further restricted by Xiang Qi's internal boundaries. This is why Roberto Lavieri's Toccata dispenses with diagonal pieces altogether and my own progression of Xiang-Qi-influenced hex variants relegate diagonals to their Wellisch usage. The orientation is also Wellisch, following the lead of hex Shogi. Indeed my one variant that does adopt the Glinsky/McCooey orientation and use of diagonals also adopts Yang Qi's radical changes in diagonal pieces to match orthogonal ones, as its name of Liu Yang suggests.

Is mine really the first comment and rating? This variant adds originality to a well-established extrapolation of moves.

	All the traditional 'crownings' of linepieces (Shogi, Duke of Rutland, Wellisch hex &c) include the ability to capture with the extra move. Indeed you use images whose usual meaning is a piece that can capture in all its directions. Your new images could prove more popular for straightforward Rook+Knight+Ferz and Bishop+Knight+Wazir. As it happens I have been writing a page whose introduction mentions Rook+Knight+Ferz, although as far as I know it has yet to make it into any actual games.

No, quite unlike the Ajax pieces, which add an extra non-capturing move to a piece which can move with or without capturing it all its original directions. There is no direction in which Pawns can do both. See the difference yet?

In terms of the Man and Beast series of piece articles the pieces are a General, Rook, Rookranker, Rookfiler, Sennight, and row of Migrants. As the orientation in Glinsky/McCooey it is the Rookranker that is bound to its file and the Rookfiler unbound - in the Wellisch orientation the Rookranker would be unbound and the Rookfiler bound to its file. The Migrant was invented by Glinsky for his game, and use of the Rookranker and Rookfiler may well be based on this piece. Certainly the Migrant's noncapturing move is one step in the Rookranker's most forward direction and its capturing move one step in the Rookfiler's most forward directions - exactly as the Pawn's moves are as regards the Rook and Bishop.

I am hesitant to criticise a variant by one of the Polgar family, but a talent for playing on square-cell boards does not necessarily imply one for designing games for hex ones. This does look very muvch like a game by someone who has not made a great study of hex variants, as it addresses several issues of the hex board less well than variants on these pages do.

A severely bound Rookranker is really a very poor analogue to the Rook. A better piece to complement the Rookfiler here (or the Rookranker in the Wellisch orientation) would be the Moorhen - a hex piece moving straight forward/backward/left/right regardless of which two are orthogonal and which hex-diagonal. This is bound to alternate files here and alternate ranks on Wellisch boards. However it would then be logical for the Queen analogue to also include the straight sideways directions. As regards subdividing of just Rook directions, my own approach to this in Altorth Hex Chess avoided severe bindings and was also Migrant-based.

It is also odd that Migrants line up with their own edge of the board rather than - as in Glinsky's game - the far edge to which they are aiming. It would make more sense on a star-shaped board to arrange a row of Pawn analogues with the middle one furthest back rather than further forward, as in my own Flatstar. At first I thought that a 37-cell might be too small for that, but it could be done with six spaces behind to fill, in two blocks of three - rather than a single back row of five. Ther weakest piece would be doubled in number - the Rookfiler in the case of Mr. Polgar's own choice of pieces. The array prior to placing the back pieces would be (excuse the crude colouring):

It is also logical to follow the usual convention for small variants and dispense with the double-step move.

No, the Dean has no single-step move. This is why it is colourbound. It moves at least two staps diagonally or exactly two orthogonally. The piece that moves at least two orthogonally or exactly two diagonally I term the Mansion, and its own cubic extrapolations are the Outpost and Estate. The Outpost can also exist as a hex piece.

Now that I think about it I haven't devised names for pieces moving at least two staps along one kind of radial and at most two along another, but I can see that they are interesting pieces. Pieces that could be seen as Mansion+Ferz and Dean+Wazir are intermediate between the Mansion and Dean and corresponnding enhancements of full linepieces such as the Infanta and Inquisitor - whicvh could be seen as Mansion+Wazir and Dean+Ferz. If this inspires any ideas for names I would be interested to hear them.

Well most of my Quadruple Besiege variants have at least twice as many pieces with a Rook move, so that will help Checkmate to happen. Remember that the minimum to Checkmate on a board with edges is a Rook plus one's own King, so an extra Rook to effect a virtual edge should allow the same on this board.
	The geometry is not quite Moebius, it's a bit more complex than that. A single orthogonal step across a horizontal join appears as a 10:9 leap. Bishops really are colourbound and, as I say in the text, each visible 10-cell diagonal loops round dircetly on itself.

So many of your variants are an education far beyond the realm of board games, and this page is no exception. Before reading this page I was unaware that the title of Archchancellor had existed in real life, although I knew about, and have mentioned elsewhere on the site, its use in Terry Pratchett's Discworld novels. What exactly was the rôle of archchancellors among Teutonic Knights, and did they have ordinary chancellors under them? Interesting that you interpret the name for a piece in the same way that I would have done. Did you notice my view on the intuitive piece for the name and take inspiration, or is it coincidence?

The point is that the Huntsman and Hawksman are defined on a corner orientation. In this context the forward diagonal is toward the opponent's corner and the backward one toward one's own corner. The directions at right angles to these I term sideways diagonals. There are also two forward and two backward orthogonals in this orientation. Thus to sum up the differences between linepieces with 5-6 directions they divide into:
	Goldrider (face-to-face) - 4 orthogonal and 2 diagonal;
	Goldrider (corner) - 4 orthogonal and 1 diagonal;
	Silverider (face-to-face) - 4 diagonal and 1 orthogonal;

	Huntress and Hawkress (face-to-face) - 3 orthogonal and 2 diagonal;

None of this page's long-range pieces are switching. The Rhino's first three destinations are those of the Wazir, Knight, and Camel. Knight plus Camel equals famously triangulating Gnu. Likewise the even destinations (exactly as with the Mirror Rhino) are destination of the Nightrider - a straight linepiece like the Bishop and Rook and so able to make two moves in the same direction and return in a single move the same length as the two together.
	Indeed not even a Waverer, a Rhino restricted to moves of odd numbers of steps, is switching as a Camel move can be reversed in four Wazir ones. Nor is a Feverer, a Mirror Rhino so restricted, as a Ferz move can be reversed in two Zebra ones. It may be more difficult when what I am for short calling Camel/Zebra moves are stepping ones here, but it is posible.

Answering your questions in the same order:

(ii) Wazir+Dabbaba+Cross I term GOLDWAZBABA - Wazbaba is the same piece without the Cross move, just as Fearful is the Silverfearful without the Point move. The nearest name I use to Goldfearful is GOLDFEARLESS for Wazir+Cross+Tusk, Fearless being the FO form of the plain Fearful.
(ii) Yes, but not on this board. On a corner-orientation square board a Supercross would be a Ferz minus the move directly toward the player's own corner. On a face-to-face cubic board it would make the four forward Ferz moves plus the four same-rank ones.

So what happens when Lemniscate Pawns go 'off-track'?

You could be right, I was just lumping them together as 'not covered anywhere else'. One further connection is that Ferry moves along the River, but it could be regarded as a multi-cell non-capturer moving along a pair of ranks. They seem to me to fall into three groups.
	The Ferry, Halter, and Trampoline can all move, either under their own steam or with the aid of another piece, but cannot capture and have a different effect on pieces. They can therefore be considered special cases of non-capturing pieces.
	The Raft and Tardis are board sections that move - and again do not capture. They take their pieces with them.
	The Bridge, Fortress, and River do not change their location on the board but still affect how pieces move.

The skewed look is because the images of empty dark squares are too big. The width and length need setting to the same as the other squares.
The Camblam 'Knight' actually has the destinations of four simple oblique leapers - the Camel, Zemel, Antelope, and Rector. Regarding the 'pass-through' squares where allies can block it, I assume that they are in the order specified fo a move. Thus an ally up to and including 4 squares away orthogonally will block it from the 2 Camel and 2 Zemel destinations in that general direction, and an ally up to and including 4 squares away diagonally will block it from the 2 Antelope and 2 Rector destinations in that general direction.

Like WinBoard, ffendiag also has no distinct Gold or Silver symbol, so I have taken to using the symbols for the Wazir and Ferz of which they are enhancements. This is why I have made little reference to Makruk and Sittuyin in my own variant. It is also why my Shoxiang family of variants add only the outer-file Xiang Qi pieces to the Shogi set.

The Threeleaper and Fourleaper in their full 3d glory - Ninja+Trebuchet and Sabbaba+Drummer+Cobbler - are in MAB 19, as indeed are the full 3d Rooteighteenleaper and Rootthirtytwoleaper - Nimel+Tripper and Furtherlump+Minorlump+Commuter - and the Fiveleaper and Rootfiftyleaper existing in 2d anyway - Antelope+Quibbler and Namel+Quitter. The radial 2d components of these and their compounds are in MAB 06. These compenents of the Threeleaper/Fourleaper/Fiveleaper/R50leaper I there term Trebuchet/Cobbler/Quibbler/Quitter. The compounds are Trebuchet+Tripper=Trilby, Cobbler+Commuter+Colby, Quibbler+Quitter=Quilby, Tripper+Cobbler=Macette, Tripper+Quibbler=Bezette, and Commuter+Quibbler=Rigette. I suppose logically MAB 19 could include the full Threeleaper+R18leaper=Nintu+Trilby=Threetriangulator and the like. Would anyone welcome inclusion of such pieces?

Ome-step divergent pieces are in MAB 02. Fusilier is, I believe, an alternative name for the Steward, the piece that moves without capturing as a Wazir and captures as a Ferz. The piece that moves with or without capturing as a Wazir and captures as a Ferz is the Xaja Wazir. The Ajax Ferz moves without capturing as a Wazir and with or without capturing as a Ferz. The piece that moves without capturing as a Ferz and captures as a Wazir I term the Contrasteward, but I once saw it termed the Guardian somewhere since, probably only a problematist usage so far. It would be interesting to know if anyone thinks it worth substituting Guardian for Contrasteward and devising similar replacements for Contrawaiter and Contrabutler.

Out of curiosity, does anyone think that I'm flogging a dead horse by terming the MAB 12 Sextoranker+Ninjafiler compound Mule? This is something of a dead-end name for a Stockable piece (i.e. one like the Brook, Fwezir, et cetera), as I am noticing as I introduce ever more such pieces. Were it called the Nsexton as copying the logic for radial pieces would dictate I could then extrapolate to Elfranker+Underfiler=Uelf, Fenceranker+Lectufiler=Lfencer, Brook+Nsexton=Nsenvasser, Unicorn+Nsexton=Nsefila, Brook+Uelf=Nleaseholder, Unicorn+Uelf=Nleprechaun, et cetera. The Stock forms of these, which MAB 15 would cover, are Stock analogues to the Camel, Zebra, Marshal, Cardinal, Canvasser, and Caliph. I could also name analogues for the Gnu/Gazelle/Bison if to Sexton+Elf=Morgai and Ninja+Lecturer=Coallure I added names for Ninja+Underscore, Sexton+Fencer, Elf+Fencer, and Underscore+Lecturer.

This looks a promising variant. If I understand it correctly the move from either pole to any adjacent cell is both an orthogonal step and a diagonal one. The position of the Elephants looks a bit awkward, but given that it gives them access to the pole it's not as bad as it first appears. Since other pieces are where they need to be (to preserve patterns such as Knights threatened by Cannons but covered by Rooks) It seems that the Elephants have to go on the rank where you've put them. One small quibble: it would be better if you didn't set the links to automatically open a new window, as those who want a new window can always click with Shift held down. Some of us don't like to clutter our task bars up, and would rather go foreward and back within a single window.

Decimal Quadruple Besiege. Army based on Échecs De L'Escalier arranged on enlarged Quadruple Besiege board. (20x20, Cells: 200) [All Comments] [Add Comment or Rating]

I've finally realised what kind of topology Quadruple Besiege boards have. It's a torus with a twist. If you join the array shown end to end to form a cyclinder, you then curve the cylinder further as if to make a normal torus, but twist one end by 180° just before actually making the join. Not a Moebius strip, not a Klein bottle, but a torus with a twisted tesselation.

Thanks for changing the links. Fair point about the Cannons, it's an absolute prevention rather than a mere deterrent. It occurs to me that you could also have a Spherical Shogi on the same board. The board could have a King on each pole with a wraparound form of this array in between:
I include the extra rank so that there would be four ranks of each camp plus four ranks in between, even if the actually numbers of cells - 28 per camp, 36 in between - would be different.

The rating is really for the whole family of variants, which has inspired to scrap Bolyar extrapolations and go for Ajax extrapolations instead. I just wanted to thank you for pushing me that extra distance, and hope that the choice of heroes named for other directions is to your liking. For now I've put such pieces using the hybrid diagonal aside.

He may have unwittingly missed the crucial word 'enemy's'. I started a game with him some time ago but do not recall finishing it. I would hope that the winner is the player with Wazirs.
