Atlantis Chess. Instead of moving, a player may remove an square from the edges of the board. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Dane,
Yes, the board can be cut in two. Yes, knights can jump over removed squares just like they jump over occupied squares. I'm not sure what you mean by 'special rule'.

Fluid Chess. A modest variation allowing movement through friendly pieces. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Jeremy,
If you're going to divide pieces into their directional components, I suggest that you also make the captures kamikaze.

Bland Chess. Chess with no diagonal moves. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Doug Chatham wrote on Fri, Oct 5, 2007 11:47 PM UTC:

'Bland Chess' seems to me to be an unfortunate name. If Taxicab weren't taken, I'd suggest 'Taxicab Chess' since the rules remind me of taxicab geometry. Unfortunately, I don't have a better alternative. ('SNEW Chess'? 'Straight and Narrow Chess'?)

Is there a variant where the pieces are only permitted to move to, say, white squares? (I suppose there have to be an extra rule to force the White King off its black square so it could be threatened.)

Black Holes. On 5 by 8 board with holes as pieces which also can be used for transport. (5x8, Cells: 40) [All Comments] [Add Comment or Rating]

I guess the S is short for 'Springer', the German word for 'knight', or something similar.

Joe Joyce,
See this page for a description of what a 'mutator' is.

Variants with Queens. Some variants, mostly dealing with queens, and mostly modest. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Nice list. Here's another suggestion:
Deposable queen (Cinderella? Were-Queen?): If a promoted Queen crosses or lands on its side's second rank, it turns back into a pawn.

Penturanga. Chaturanga on a board with 46 pentagonal cells. (8x5, Cells: 46) [All Comments] [Add Comment or Rating]

Doug Chatham wrote on Mon, Dec 3, 2007 06:40 PM UTC:

George,
The old CVP-linked pentagonal game that you mentioned, is it Webball, which is played on a dodecahedron?

Maybe in a few years, we'll be able to 'print' the board and pieces using a 3-dimensional printer like the one described on this video: http://www.youtube.com/watch?v=39VJP671LDY

To the person who is confused by the 'one and one' knight's move description:

Read the description of the knight's move again. It's one horizontally or vertically, and then one diagonally. The 'one and two' description you're thinking of doesn't mention diagonal movement -- it's one vertically, then two horizontally or it's one horizontally, then two vertically.

Both descriptions get the knight to the same places.

Yes, promoted pawns can be immediately captured after promotion. The opponent is not required to wait. See the Pawn FAQ page for more details on the question 'Can promoted pieces be captured directly after promotion?'.

Mutators. Article discussing the concept of Mutators.[All Comments] [Add Comment or Rating]

Doug Chatham wrote on Tue, May 20, 2008 10:44 AM UTC:

Do you have any example of an atomic mutator? It seems to me that all mutators are composite: for example, [Pass] could be factored as [Pass, if White][Pass, if not White].

Doug Chatham wrote on Wed, May 21, 2008 10:01 AM UTC:

Article 9.3 of the Laws of Chess says 'Declaring a check is not obligatory.' So, you weren't even required to say 'check', much less 'checkmate'.

King's Guard Chess. Pawns move like kings and only Pawns may capture. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Doug Chatham wrote on Fri, Jun 13, 2008 02:26 PM UTC:

What happens if I capture the opponent's last pawn on the last row with my last pawn, which must immediately promote since it's on the last row? More generally, what happens if both players achieve a losing condition at the same time?
