체커 — 규칙

Pool

• Pool checkers (American pool, APCA rules) is played on an 8×8 board of 64 alternating dark and light squares. Two players take part, each with 12 pieces of their own colour, called white and black.

• The board is placed so that a dark corner square is on each player's left. The pieces stand on the dark squares of the 3 rows nearest to the player. Black moves first, then the players take turns.

• The object of the game is to capture or block all the opponent's pieces. A player who has no move on their turn loses.

• A man moves one square diagonally forward to a free square. It captures forward and backward: it jumps over an opposing piece to the free square right behind it and keeps capturing while it can. A piece may not jump over pieces of its own colour.

• A man that ends its move on the last row becomes a king. If it reaches the last row during a capture and can capture further backward, it goes on capturing as a man and does not become a king.

• A king moves forward and backward along a diagonal over any number of free squares. After capturing a piece it lands on a free square behind it on the same diagonal and keeps capturing, also turning onto another diagonal. A king may not jump over pieces of its own colour.

• Capturing is mandatory. The way to capture is a free choice, not necessarily the one that takes the most pieces. If there are several free squares behind the captured piece and the capture can continue from at least one of them, the king must land on such a square. A capture once started must be completed.

• The same opposing piece may not be jumped twice. Captured pieces are removed from the board after the whole move.

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

• Draw:

  • the same position has occurred three times;
  • exactly 4 pieces on the board, all kings, 3 against 1: a draw if the lone king has made 13 moves without being caught; if the lone king stands on the long diagonal, after 5 moves by the stronger side;
  • 30 moves by each side without captures and without promotions.

Source: APCA rules. Under the code a draw after 30 moves has to be claimed; on VOG it is recorded automatically. After a capture or a promotion the count here starts again at 30 moves; under the APCA code it is 20.
