Alekhine Defense Four Pawns Attack Back Rank Mate in Chess

In the Alekhine Defense Four Pawns Attack, Black accepts an early pawn thrust and aims to exploit White’s overextended pieces and weakened back rank. The defining feature is the sharp, open position after the Four Pawns setup, where White often has limited escape squares and the king’s defenders get tied down. “Back rank mate” here means Black delivers a mate by controlling the last rank (usually with a rook/queen) while preventing the king from escaping or capturing the attacker.
