We consider Gardner’s minichess variant in which all pieces are set as in a standard chessboard (from Rook to King). This game has roughly 9 × 10 legal positions and is comparable in this respect with checkers. We weakly solve this game, that is we prove its game-theoretic value and give a st...

Many research teams and individuals have computed endgame databases for the game of chess which use the distance-to-mate metric, enabling their software to forecast the number of moves remaining until the game is over. This is not the case for the game of checkers. Only one programming team has generated a checkers database capable of announcing the distance to the terminal position. This paper...
