David,
Yeah, King-and-Pawn endings would be a problem with my 'promote-only-to-live-species' rule. Either one would have to make some sort of exception, like 'When there's nothing left but Pawns and Kings, then you can promote to anything' or 'A Pawn can always promote to a ..er.. Man' -- or one would have to somehow shorten the game so that Pawn-and-King endgames never occurred (e.g Extinction Chess, which follows my rule in a trivial sense).

Well, if you like the large number of setups, here's another idea you may
find amusing: Googol Chess.  In Googol Chess, each square points to a
particular non-adjacent square randomly chosen during the setup.  A piece
has the additional power to leap to the square pointed to by its current
square, if that destination square is empty.  There are at least
(64-9)^64=55^64 > 2.1 x 10^111 possible setups on a standard chessboard.

laura, That's the second question on the Rules of Chess FAQ page. Here's the answer:
Can kings check other kings? No. A king may not move to a square next to another king, because then this move would put the king that moves also into check, which is illegal.

It is possible to make a move with a king such that the other king is checked (or even mated): suppose that whites king is between whites rook and blacks king on one line. When the king moves away from the line, he discloses the check by the rook.

dj,
See the answer to next-to-last question on this page. You don't automatically win if your opponent falsely claims checkmate.

Try reading this page on the 50-moves rule: http://www.chessvariants.org/d.chess/50moves.html.

Editors: Maybe there should be a link in the 50-moves paragraph of this Rules of Chess page to the 50-moves FAQ page.

Rico,
If it's a draw, then neither player wins and neither player loses. In a tournament game (where a win gets 1 point and a loss gets 0 points), each player would get 1/2 a point for the draw.

bryan,

To make an en passant capture, the attacking pawn must be on the opponent's fourth row. Also, if you capture en passant, that is your move -- you don't get a bonus turn. For more information on en passant, see this FAQ page.

No. A king may never move itself next to the opponent's king. Period.

See the Chess FAQ for more information.

Anyone aware of amusing alternate appellations for the other chess pieces? For example, did anyone grow up calling the pawns 'midgets'?

Yes, you could set up a transit system that'd work on a chessboard. If you want a more exact duplicate of chess, you should add 'Restricted' pieces that are only allowed to use specified routes.

Roshan,
According to Article 8 of the FIDE Laws of Chess:
If, during a game, it is found that an illegal move was made, the position shall be reinstated to what it was before the illegal move was made. The game shall then continue by applying the rules of Article 7 to the move replacing the illegal move. If the position cannot be reinstated, the game shall be annulled and a new game played.

So, either put the pieces back where they were before you exposed your king, or cancel the game and start over.

Sorry, (zz038)A. Black, I didn't mean to imply that you personally were looking for a duplicate of chess. The second sentence in my previous comment was an attempt to preemptively answer an anticipated question from some as-yet undetermined 'you'.

Anyway, I believe you can set up a game of 'Chess on a Mass Transit System' on a chessboard or any other sort of game board.

Since Scrabble has neither determinism nor perfect information, it seems that removing those elements from chess won't necessarily prevent Scrabblization.

According to The Classified Encyclopedia of Chess Variants (p. 51), Jaime Poniachik invented this game in 1995 under the name 'Banana-Skin Chess'. Editors, please make the appropriate corrections.

I apologize for my error.

I'd like to submit the following theme ideas:
  1. An X-squares contest: The number of squares would be variable, changing during the game. An example would be Tile Chess.
  2. A 45-piece contest
  3. A 3-player variant contest
