Dice chess can refer to a number of chess variants in which dice are used to alter gameplay; specifically that the moves available to each player are determined by rolling a pair of ordinary six-sided dice. There are many different variations of this form of dice chess.〔John Gollon, ''Chess Variations: Ancient, Regional, and Modern'', Charles E. Tuttle Company, 1974, pp. 231-32. ISBN 0-8048-1122-9.〕 One of them is described here. ==Rules== The players alternate rolling the dice and, if possible, moving. On each of the dice, the one represents a pawn, two a knight, three a bishop, four a rook, five a queen, and six a king. The player may move either of the pieces indicated on the two dice. For example, a player rolling a one and a two may move either a pawn or a knight. A player who rolls doubles (the same number on both dice) may play any legal move. Otherwise, standard chess rules apply, with these exceptions: * a player who has no legal move with either of the pieces indicated by the dice loses that turn (passed turn); * if castling is otherwise legal, a player may castle upon rolling a four, six, or doubles; * an en passant capture of a pawn is possible only if the player rolls a one, or doubles, immediately once the opportunity for the en passant capture arises; * a player who is in check can only play a legal response to that check (capturing the checking piece, moving the king, or interposing a piece); * a player who is in check but does not make a roll allowing a legal response to the check loses that turn, but does not automatically lose the game; * except in the unlikely event that the game ends in a draw pursuant to the standard rules of chess, the game ends when one player either checkmates the opponent or captures the opponent's king. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dice chess」の詳細全文を読む スポンサード リンク
