Alekhine Defense Four Pawns Attack Discovered Attack in Chess

In the Alekhine Defense Four Pawns Attack, Black accepts a pawn center and often plays ...d5 to challenge White’s advanced pawns. The “discovered attack” element appears when a move (commonly a pawn break or piece shift) opens a line—typically for a rook, bishop, or queen—so an attack on a key target suddenly becomes possible. For an intermediate player, the defining feature is that the tactical shot relies on opening a line while the opponent’s pieces are momentarily pinned, overloaded, or aligned.
