A '''Sacrifice''' is a move offering a pawn or piece in the hope to gain [[Tactics|tactical]] or [[Strategy|strategical]] compensation. The opponent may be forced to accept the sacrifice or may otherwise have the option to decline it.
Chess programs usually need some remaining [[Depth|depth]] left from the [[Horizon Node|horizon]], to find the compensation and to distinguish sacrifices from [https://en.wikipedia.org/wiki/Blunder_%28chess%29 blunders], either by forced tactical [[Combination|combinations]] or by positional long term damage considered by huge positional [[Evaluation|evaluation]] terms, most likely [[King Safety|king safety]] related. If, during a [[Chess Game|game]], the opponent offers an unexpected sacrifice, the program's [[Time Management|time management]] should have the "take care" flag on. It might be a good idea to don't play too fast, happy with winning some [[Material|material]].
