Marseillais Chess. Move twice per turn. (8x8, Cells: 64) (Recognized!)[All Comments] [Add Comment or Rating]
Doug Chatham wrote on Sat, Dec 18, 2004 11:17 PM UTC:
On page 21 of his book Popular Chess Variants, D. B. Pritchard writes, 'The en passant rule has seen change. Modern players allow it only when the pawn advance formed the second move of a turn.'

This implies that the opponent cannot capture two men with one en passant move.


Bellows Chess. The board expands and contracts from turn to turn. (12x12, Cells: 144) [All Comments] [Add Comment or Rating]

Tony,<p> Why not have your pin piece go from its 12 x 12 corner to a second (i.e. different from the corner you're already using) 10 x 10 corner back to the original 8 x 8 corner?

Move 3 in your sequence isn't valid. A pawn cannot leap over another piece.

Bachelor Chess. Win by mating your opponent, or marrying off your King. (7x6, Cells: 42) [All Comments] [Add Comment or Rating]
💡📝Doug Chatham wrote on Fri, Jan 14, 2005 02:09 PM UTC:
Yes, that is correct. If you have a friendly Queen next to your King at the end of your turn and your King is not in check, then you have won by marriage.<p> Charles, your comment has made me realize that rule 3 needs a slight correction to include marriage by pawn promotion.

If there are 35 mutable rules (and 209 is still in effect), the player still has the option to propose transmuting a rule to immutable status or to propose repealing a mutable rule.

Contest: the 9 Queens Problem. Put 9 queens and 1 or 2 pawns such that queens do not see each other. Send your solution before Feb 29, and win a book![All Comments] [Add Comment or Rating]

GEOFX_BBFC,<br> <p>It looks like the last part of your list was cut off. Your list has only 98 solutions, but there are 128 solutions to the '9 Queens Problem' <p>You may find the following PDF files interesting:<ul><li><a href='http://people.moreheadstate.edu/fs/d.chatham/N+1QP.pdf'>The N+1 Queens Problem</a></li><li><a href='http://people.moreheadstate.edu/fs/d.chatham/queenssep.pdf'>The Queens Separation Problem</a></ul>

Big Outer Chess. Large variant with concentric circles on the board, so there is less concentration on the centre. (12x12, Cells: 148) [All Comments] [Add Comment or Rating]

Another CV with self-modifying rules is Nomic Chess, an attempt to combine Nomic, Peter Suber's game of self-amendment, and Ralph Betza's Chess for Any Number of Players.

In your version of Bachelor Chess, the Bishops can only reach half the squares --- they both start on the same color. Is this a bug or a feature?

A game on a board this small deserves the shortest possible name. I suggest IO :-)

Doug Chatham wrote on Mon, Mar 7, 2005 06:49 PM UTC:
Earlier, someone published a side challenge to produce a variant with exactly 10 squares. I have another side challenge: the Obfuscated 10 -- Make a chess variant where the number 10 plays significant but <b>hidden</b> roles. At least one such role should be something not shared by other chess variants, so 'played by 10-fingered beings' doesn't count.

Doug Chatham wrote on Tue, Mar 8, 2005 02:05 PM UTC:
A modest suggestion for an extra challenge: <h3>The Hidden Ten</h3> <p>Make a chess variant where the number 10 plays only non-obvious, 'hidden' roles. At least one of these roles should be something not shared by other chess variants --- so 'played by creatures that use a decimal number system' isn't sufficient for this challenge.</p>

I see nine entries so far.  Perhaps the editors are fighting over who gets

One of the rules of this contest is that no changes to a submission are allowed after April 30. Now that some of us can edit our own pages, will that restriction still be enforced?
