チェッカー — ルール

Thai draughts (Mak-hot)

• 8×8 board, each player has 8 men on the dark squares of the two nearest rows. White moves first.

• A man moves one square diagonally forward and captures forward only.

• A man reaching the last row becomes a king. If this happens during a capture, the move ends there.

• A king moves diagonally any distance. It also captures from a distance, but must land on the square directly behind the captured piece and continue capturing from there. A capture may continue only in the same direction or at a right angle to it — never back along the same line.

• A captured piece is removed at once, so its square can be crossed later in the same move.

• Capturing is mandatory and a capture must be carried through to the end. You may choose any capture; there is no majority rule.

• A missed capture does not cost a piece: the server simply will not accept such a move.

• A player with no legal move loses. Draw: threefold repetition; 20 moves each with kings only and no capture; a king against a king when the player to move cannot capture and can step out of danger.
