Wizard's Chess

From Harry Potter Wiki

Wizard's Chess is the magical variant of the classic board game in which the pieces move of their own accord when commanded by the player. When a piece is taken, it is destroyed by the attacking piece. Players move their pieces by speaking the name of the piece and the square it is to move to. When Harry Potter began to learn how to play the game, he used the pieces of Seamus Finnigan, which offered him bad advice because they knew that he was not a good player.

During the Christmas Feast, in a number of Wizard Crackers, Harry obtained, among other things, his very own Wizard's Chess set. He later broke it in by losing, once again, to Ron. (Although Harry saw this more as the fault of Ron's brother, Percy Weasley)

During 1992 a giant Wizard's Chessboard was the third-to-last layer of security for the Philosopher's Stone. Using his extensive knowledge of chess, Ronald Weasley managed to get him, Harry, and Hermione Granger across, ultimately sacrificing himself to the White Queen so that Harry could checkmate the King.

Aside from the self-moving pieces, the rules of Wizard's Chess appear to be identical to those of standard chess.
