sac

Chess slang word, abbreviation of word "Sacrifice".

In chess, a sacrifice usually means a move that gives up a piece with the objective of gaining tactical or positional compensation, maybe even straight checkmating the opponent. Also, often used while capturing a piece of a lower value with a stronger piece, especially a Queen.

1. "...and if he takes, then you can sac your Queen for his Rook and the Pawn is unstoppable!"
