Compromise ChessCompromise Chess was invented by Fred Galvin in 1958. A closely related variant to this game is Refusal Chess. Compromise Chess is the one of the two that is more suited for correspondence games, while Refusal Chess is more suited for face-to-face play. Compromise Chess is regularly played in AISE and NOST.
A variant of Compromise Chess is Choice Chess.

The button below can be used to refuse the latest move of the Diagram's AI, if it was not the only legal move.
RulesAll rules are as in normal chess, except for the following: each turn, the player who's turn it is to move must select two legal moves. His opponent then selects one of these two moves, which then is made. When a player has only one legal move, he makes this move. Two promoting moves with the same pawn, but promoting to different pieces, are considered two different moves. A move that is not selected may be proposed the next (and later) turns.
Choice ChessThis variant, invented by Bruce Trone in 1986, differs only in one aspect from Choice Chess: each turn, a player proposed five legal moves. When a player has less than five possible legal moves, his opponent just selects one of these possible legal moves.
