Alice Chess

Rabbit is a program for playing Alice Chess. Alice Chess is a chess variant inspired by Lewis Carroll's writings "Alice's Adventures in Wonderland" and "Through the Looking-Glass". The game is played on two boards instead of one. The second board is initially empty. After each move is completed, the moved piece is automatically transferred on the opposite board (in other words, it goes "through the looking-glass"). Apart from that, all standard chess rules apply (including stalemate, castling, double pawn move, en-passant capture etc.). Additional explanations about the rules are available in the program, see the help menu. See also this page for more details on Alice Chess (rules and strategy).

Rabbit

Rabbit allows one to play against an AI or another human player (on the same computer). Several variants and game options are available, see the help menu of the program for details. For instance the black pieces may be placed on the opposite board at the start of the game, it is possible to play with three boards instead of two etc.

The AI is based on a minimax algorithm with usual pruning heuristics and a straightforward evaluation function taking into account material and mobility. It is not as smart as AlphaZero :)
