Three Knights Opening Schlechter Variation Puzzle (Rated 939): Win Material — Discovered Attack

This middlegame puzzle is a classic example of a discovered attack combined with a forcing check. White’s active bishop creates a tactical interruption that exposes the black queen and central king at the same time. The key idea is not a long attack, but a short sequence that wins material by exploiting alignment, king safety, and a trapped queen. In classical chess, these motifs often appear when one piece is overloaded and the opponent’s king is still uncastled.
