Semi Slav Defense Discovered Attack Puzzle (Rated 1320): Win Material — Discovered Attack

This middlegame puzzle is built around a classic discovered attack idea: one piece moves with tempo, opening a line for another attacker and forcing a tactical response. The key feature is that the enemy queen is overextended and vulnerable, while the white queen and bishop coordinate against the center and king side. When the trigger move appears, the position becomes a tactical refutation where material can be won immediately through a forcing sequence rather than a slow positional plan.
