An animation showing examples of capturing pieces in atomic chess. The game is played using the standard rules of chess, but with the variation that all captures result in an "explosion" in which all surrounding white and black pieces, other than pawns, are removed from play. Some variations additionally remove rules concerning check such that the king may be able to move into or remain in check. The game was introduced in 1995 by the German Internet Chess Server, based on rules one of its users collected from friends who played offline. Since then it has been implemented at Chess Live, the Internet Chess Club, Free Internet Chess Server, and Lichess.Animation: Rhododendrites
