To clarify, this society is still alive and well. Indeed, they had a 2005 world tournament (on the set of The Da Vinchi Code no less), and are already planning a 2006 tournament.

Since the King is not royal, can the King put itself in check or castle through check?

To clarify, I don't have any problem with this variant; I just think the initial name was not the best. It is possible that the amazon gives white a winning game from the get-go, but we need playtesting to confirm or deny that.

You can probably use the Zillions of Games file for Shanghai Palace Chess as a basis to make your own Zillions' file.

This is a general comment on all of Mr. Gilman's games: I would be far more inclined to look at the games and see how they play if Mr. Gilman learned how to make Zillions rules files for his games. This both makes it easier to play his games, and resolves any ambiguity in his rules.

I'm curious. Why a RMBNQKNBMR opening setup instead of a RMNBQKBNMR setup? I like having the knights and bishops in the same places that they are relative to the king in FIDE Chess; swapping the bishops and knights like that just seems to make the pawns get in the way of the bishops.

As an aside, another of Greenwood's variant with this piece is Tamer Spiel (a 2002 variant) where it is called the 'Lion'.

Sam Trenholme wrote on Mon, May 8, 2006 04:19 AM UTC:
I think those are good points. Then again, the A and J pawns on an 8x10 setup are poisoned pawns for the bishop; if the bishop takes, say j2, the move pawn to I3 traps the bishop. As for hindering b3/I3 development, since the mammoths are about as valuable as archbishops, they are pieces which will probably not be developed until the later mid-game, when the bishops are no longer on their home squares. Also, the high level of power and relatively slow movement of the mammoth makes them more suited as defensive rather than offensive pieces.

I think the solution to the castling problem is to use the castling rules that grotesque chess has.

I agree. A chatroom for us chess variant geeks.

Maybe we can create a club where we study the opening lines of some random pure-chance recognized variant each week.

When a king moves to the seventh rank, creating pawns on the eight rank, what happens with the pawns?
  • Are the pawns immediately promoted?
  • Are the pawns left on the eight rank and are immobile?
  • Are the pawns left on the eight rank, and can be promoted as a future white move?
  • Or does on place a piece besides a pawn in his guard on the eight rank?
As a related question, can the pawn promote to an Ubi-ubi?

One interesting Chess variant which tries to solve White's first-move advantage is Pie Rule Chess, which works as follows:
  • White makes a move.
  • Black then decides whether he wants to play with the white or black pieces.
  • The came then continues as normal (with the possibility of the players swapping seats).
Now, in terms of what side to play based on the 20 possible opening moves of FIDE chess, here is the choices I would make:

First moveSide to play
a3Black
a4Black
Na3Black
b3???
b4???
c3Black
c4White
Nc3White
d3???
d4White
e3???
e4White
f3Black
f4???
Nf3White
g3???
g4???
h3Black
h4Black
Ng3Black

Any other opinions on using the pie rule in FIDE Chess?

Edit: I note that the Pie Rule does nothing to discourage Black from playing to draw. My answer to the draw problem is to make it so both players get 0 points (instead of half a point) in a drawn game; both players lose. Or have it so that the player with more material on the board wins .75 points after a three-fold repetition/50 moves without capture/insufficient mating material position. We can also consider the Ko rule for chess: You can not repeat a position on the board that has been already played.

Looks good.  I can't comment on it further until I see a Zillions

Maybe I'll make a Zillions preset one of these days...

As it turns out, there are 9,820 opening setups for Carrera chess where the king is to the left of the queen and between the rooks, the bishops are not next to each other, and all pawns are defended in the opening array. (Read my recent post on the chess variants mailing list for details).

As I commented before, I like the idea of a variant that has many different possible permutations.

I'm very very happy to see this new release! I was worried that ChessV was abandoned (the last ChessV public release had a bug that made it not play chess as well as it could). This is a great program; I'm glad it supports my game (Schoolbook) since playing Zillions has been getting old.

If you're interested, I can help by having a command-line version that can compile uisng the standard Gnu/UNIX toolchain--it would be nice to compile this program on something besides Windows + MSVC. I think that would encourage more developers (I'm a Linux developer who makes Windows ports with MingW32).

Again, thanks for the great work Greg. Good to see you back--I missed you!

As for extratracting ChessV, it's a lot better to extract it using Windows XP's built-in .zip extractor. Basically, since I don't have Winzip, I just double click on the ChessV zip file, which will open up a window with a folder called 'ChessV'. I copy this folder (right click, copy) and paste it in the C:\ folder. This gives me a ChessV folder that I can play ChessV from.

Winzip has a way of destroying all of the subfolders that a .zip file has; this will break ChessV. The solution is simple: Don't use Winzip. WinXP's .zip extractor is simpler, better, and cheaper.

Sam Trenholme wrote on Tue, Aug 29, 2006 08:24 PM UTC:
The reason why I named the rook + knight piece in Schoolbook a 'Marshall' instead of a 'Chancellor' is because the Archbishop is sometimes called a 'Cardinal' and I wanted the first letter of the name for the rook + knight piece to be an unambiguous one. 'C', IMHO, is for the Camel (1,3 colorbound knight).

One feature I really like about ChessV is the 'test this position' feature. This is a veryuseful feature for helping build up an opening book for my Schoolbook variant; I've been spending all of last weeking using ChessV to help me come up with some opening lines in Schoolbook Chess.

I'll post some basic opening theory for Schoolbook later on this week. As a start, I like the way white's position looks after 1. f4 Nd6 2. g4

Dragon. Missing description (9x15, Cells: 135) [All Comments] [Add Comment or Rating]
Sam Trenholme wrote on Sun, Sep 10, 2006 02:22 PM UTC:
I have been watching this flame war for the last few days and have decided to finally add my two cents.

Dragon feels like one of those complicated war games that Avalon Hill used to make, before they went out of business (OK, bought out by Hasbro) in the late 1990s. Now, when Avalon Hill was bought out, many, many people on Usenet were upset. Avalon Hill war games did not have enough general appeal to sustain the company, but their games did have a small group of very dedicated devotees.

In terms of why people go to this site, in my case I feel that FIDE chess has been over-analysed, with many opening variations over 20 moves deep. Also, the most common defense against 1. e4 for black is the Sicilian, which Morphy (my favorite player) referred to as resulting in 'uninteresting games and dreary analytical labours'. Even Kasparov recently stated that 'the volume of opening theory has reached threatening proportions and calls for need to find a way to alleviate the pressure of the endless opening databases'.

I feel these issues can be addressed by fairly minor modifications to the rules of chess. Many chess players agree; when Bobby Fischer said that 'Chess is dead', he was promoting his own Fischer Random chess. Indeed, Kasparov has given Fischer Random (where the pieces are shuffled) a reluctant endorsment, pointing out that most random shufflings of the Chess pieces 'are poison to your eyes'.

My own endorsment is the same one Capablanca had: A 10x8 board with a rook + knight and bishop + knight pieces added. Making the board just a little bigger greatly increases the number of possible opening setups. 8x8 chess can only have 1,440 unique setups of the pieces; a 10x8 board has 126,000 possible opening setups.

But I'm diverging.

Back to 'Dragon' (not be be confused with Gygax' 'Dragon Chess'), I think this game would be a lot more playable if a computer program could help enforce the rules. I encourage Glenn Nicholls to make either a computer program that can play this game, or a Zillions preset, so that people can more easily see if this game suits their tastes or not.

And, yes, 'Dragon Random' would have a huge number of possible opening setups.


So what's YOUR favorite?. Yeah, we've got a list of recognized variants. But what games are YOUR personal favorites?[All Comments] [Add Comment or Rating]

I agree that Andy crossed the line of being civil and it seems to me that he is just looking for a flame war. Andy: If you want to flame people, there are many sites which are flamer-friendly. Chessvariants.org isn't one of them.

I think the problem is that Andy wasn't fully able to see that he hurt Glenn's feelings when he was critical of his chess variant. It is very hard to be critical of a chess variant; see this discussion where I was critical of a variant.

In terms of Dragon, as I said before, I won't play it until a computer implementation is made, and Glenn is currently unwilling to make one. But, yes, I think this kind of Chess + wargame hybrid is a good idea. The rules are a bit complicated for my taste to try and learn this game unassisted, however. Then again, I never played anything more complicated than Axis and Allies without a computer.

I'm adding an excellent rating mainly to counterbalance Andy's poor rating.

I think the issue here in terms of the complex rules is a generation gap issue. A lot of younger people feel that a game can't have complex rules. They are probably not aware that in the late 1970s and 1980s, people were perfectly willing to go to the effort to learn complicated boardgames like Squad Leader.

My issues with the game are that I don't feel Glenn has gone to the effort to fully implement this game. The diagram would look nicer if he used images instead of letters. Then again, the counters in Squad Leader had only the most basic of graphics, with letters and numbers indicating the unit's strength. So Glenn is being consistant with an old wargaming tradition. It would be nice if Glenn made a computer implementation of this game, but back in the Squad Leader days, computers were too expensive and specialized to be widely used by wargamers. Another issue is that, if Glenn wants to fully implement a complex Avalon-Hill style game, he needs to have simplified forms of the game so people can learn all of the rules step by step; this is what Avalon Hill did with their complicated games.

This game is a hybrid of the complex wargames of days long past and Chess; to say that such a game has rules that are too complex displays a profound ignorance of an entire gaming culture.

As a final note, a 'you can't reply to criticism to your game' rule would stop a lot of flame wars here. Then again, it would also give trolls who just want to hurt people's feelings more power.

'There 12118 positions still are remaining'

My program counts 9819. Here are my restrictions:

* All pawns defended

* King between rooks

* No bishops together

* No RNBQMKABNR setup (patented; M = Rook + Knight; A = Bishop + Knight)

I'm curious where the number 12,118 comes from.

Hey, is it ok if I add, to the next release of my Schoolbook Zillions file, a version of Capablanca Shantraj with the Schoolbook opening setup to the list of variants? I think it will make for an interesting game. Who knows, if Greg gets time, he may even figure out the values of the knight + wazir + dabbah and knight + ferz + bishop on an 8x10 board and add a 'Capablanca Shantraj' to ChessV. BTW, what's the official opening setup for Capablanca Shantraj? RNBAQKMBNR or RNABQKBMNR? (A = Ferz + Alfil + Knight, M = Wazir + Dabbah + Knight)
