user10737: Is there any variation of chess where the winner has to take all of the opponents pieces rather than just force the capture of one of them ?
I guess sacrifices wouldn't work well in this variation of chess.

user11629: Horde/Dunsany's chess would match your requirement for one side (the other has to mate).

user3819: First of all, the historical rules of Shatranj include the victory condition "bare King", i.e., capturing all pieces except the King is a victory, except that the other player can capture the last piece of the first player immediately after the loss of his last piece (then, the game is drawn).
As a modern variant, there is Extinction Chess (aka Survival of the Species) where the extinction of one piece type (Knight, Bishop etc.) wins the game.
