Slav Defense Geller Gambit Puzzle (Rated 1480): Win Material — Tactical Refutation

This middlegame puzzle comes from a Slav Defense structure where king safety outweighs everything else. White’s attacking pieces are aimed at the black king, but the key idea is that the position contains a tactical refutation based on a vulnerable king and an overextended piece. The winning side can exploit a hanging piece and force the opponent’s king into a sequence of checks and captures that leaves the attack collapsing into material gain.
