Moves and Notation
To make a move, you simply send a message with the move in the appropriate notation. An example of a simple move could be
d1e2, moving a piece diagonally forward, from the origin square
d1 to the destination square
<origin square><destination square>
Capturing is done by jumping over an opponent's piece. For example, if you have a piece on
d1 and want to capture the piece at
e2, you can send the message
If you want to capture multiple pieces, you can chain the moves together. For example, if you have a piece on
d1 and want to capture the pieces at
e4, you can send the message
d1f3d5 (or shortcut to
d1d5 in case the move in unambigious).
As in all forms of draughts, English draughts is played by two opponents, alternating turns on opposite sides of the board. Enemy pieces are captured by jumping over them. The pieces move diagonally, one square at a time. Pieces may only move forward, except for the king which can move in any direction. A player wins when the opponent has no more pieces or cannot make a move.
English draughts specifically is played on a 8×8 checkerboard with 12 pieces per player.
- When capturing an opponent's piece is possible, capturing is mandatory. If multiple captures are possible, the player must choose one of them. It does not matter which capture is chosen and is not required to be the one that maximizes the number of jumps in the turn.
- When a piece reaches the opponent's side of the board, it is promoted to a king. A king can move and capture in any direction. A king can still only move one square at a time (as opposed to some variants that have flying kings).
