Alekhine Defense Four Pawns Attack Trapped Piece in Chess

In the Alekhine Defense Four Pawns Attack, Black accepts a space disadvantage and then strikes with pawn breaks to create tactical threats. The “trapped piece” motif appears when White’s piece (often a knight or bishop) is forced onto a square where it has limited escape squares. A defining feature is the early pawn structure and pressure around the center that lets Black attack with tempo after White commits to the four-pawn setup.
