Lasca 拉斯克叠跳棋
(重定向自Laska)
Lasca (also called Laska or Laskers) is a draughts (or checkers) variant, invented by the second World Chess Champion Emanuel Lasker (1868–1941). Lasca is derived from English draughts (American checkers) and a Russian game, Bashni (Towers).
The game is played on a 7×7 board; as with draughts and most descendant games, play takes place only on alternating squares, so that only 25 of the 49 squares are actually used. The playing pieces are known initially as "soldiers"; when they reach the last row of the board, they become "officers", with the same ability as kings in English draughts to move and jump backwards.
