Choice of capture, promotion during a multi-capture.
Russian draughts is played on an 8X8 board as shown below. For variants on an 8x8 board two coordinate systems can be used: Fieldnumbers (1-32, similar to 10X10 International draughts) and Algebraic (a-h, 1-8).
Algebraic notation is the most used system in Russian draughts. It is also customary to indicate a capture with a colon ':' instead of an 'x', for example 'd4:b6'. The 'x' is still a valid notation for captures, and is used in PDNs for example.
You can choose which coordinate system to use in your preferences.
Moves and captures
The rules for moving the pieces are the same as International draughts, with two major exceptions: choice of capture and promotion during a multi-capture.
- In Russian draughts it is also forced to capture when there is one on the board. But a player may choose any capture that it is available, and is not forced to play the longest sequence. However, if you choose a capture, you always have to finish the whole capture. In the diagram below, white can choose to capture d4:f6 or f4:b4. White is not allowed to capture only f4:d6, because the whole capture sequence has to be finished.
- If a man touches the opponent's back row during a multi-capture, the man promotes immediately and can continue to capture as a king. If no further capture is possible with the king, the turn ends after the promotion. In the diagram below, black does not simply promote with a3:c1, but wins immediately by capturing all enemy pieces with a3:a5 (a3:c1:g5:d8:a5).
Winning and drawing
- A player wins the game when the opponent no longer has any valid moves. This can be either because all of the player's pieces have been captured, or because they are all blocked and thus have no more squares available.
- If the same position appears on the board for the third time, with the same side to move, the game is considered drawn by threefold repetition.
- If a player has three kings (or more) against one single enemy king (no men left on the board), the game is drawn after 15 moves. In other words: if the player with three kings or more does not win within 16 moves, the game is considered a draw.
- If both players play 15 kingmoves (any king) without captures or moving men, the game is drawn.
- If both players have at least one king, and the balance of the pieces remains the same, the game is drawn after:
- both players play 30 moves in a 4- or 5-piece ending
- both players play 60 moves in a 6- or 7-piece ending
- If a player has three kings, two kings and a man or one king and two men, against one enemy king that is located on the long diagonal (a1-h8), the game is drawn after both players made 5 moves.
- If a player has two kings, one king and a man or one king, against one enemy king, the game is drawn after both players made 5 moves.
