Reti Opening Anglo Slav Variation Discovered Attack in Chess

In the Reti Opening: Anglo-Slav Variation, a “discovered attack” happens when one move (often a pawn break or piece shift) opens a line so another piece suddenly attacks a target. The defining feature is that your move both creates the line and reveals an attack—commonly against the black queen, rook, or a pinned piece—while the opponent’s pieces are lined up behind the blocker.
