Gamemaster General Game Playing skirmish1 Description Skirmish is a variant of Chess. Same size board. Same pieces with the same moves, except no castling, no en passant captures, and no queening. And the game does *not* terminate when a king is captured. The object of the game is to take as many of the opponent's pieces as possible while losing as few of one's own pieces as possible. Each player's score is the sum of the points for the player's remaining pieces plus the points for the opponent's pieces that have been captured. A king is worth 11 points, and a queen is worth 9. Each rook is worth 5 points, each bishop or knight 3 points, and each pawn 1 point. (In this implementation, the point total for white is shown in the box on the left of the board, and the point total for black is shown on the right.) The game terminates after 50 moves or whenever either player has no legal moves. The winner is the player with the larger score. To make a move, click on a piece and drag to the desired square.
