Queens Gambit Accepted Alekhine Defense Discovered Attack in Chess

In the queens gambit accepted alekhine defense, the defining idea is that Black accepts the queen’s gambit and then uses piece play to open lines for counterplay. A “discovered attack” here means one piece’s move (often by shifting a defender or moving a pawn) reveals an attack on a more valuable target—typically the queen, a rook, or a king-side weakness—while the opponent is still committed to the accepted structure.
