Alekhine Defense Four Pawns Attack Interference in Chess

In the Alekhine Defense Four Pawns Attack, the defining feature is Black’s active counterplay against White’s central pawns after 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4. “Interference” here means using a move that blocks or deflects a piece/line so White’s attack on the center or along a file/diagonal suddenly loses coordination. The motif often appears when a tactical shot forces a defender to stop guarding a critical square or line.
