Alekhine Defense Two Pawn Attack Discovered Attack in Chess

In the Alekhine Defense Two Pawn Attack, Black challenges White’s center with …Nf6 and …d5, often after White grabs space with c4 and e4. The “discovered attack” motif happens when a move like …c5 or …d5 opens a line (commonly for a bishop or queen) and simultaneously reveals an attack on a key target—often a piece on a central or pinned square.
