Lemming Defense Puzzle (Rated 1296): Win Material — Tactical Refutation

This middlegame puzzle is about spotting a forcing tactical refutation when the enemy king and queen are both vulnerable. White has active pieces, a strong knight on d4, and pressure against key dark squares and the e6 pawn. The position rewards calculation over slow buildup: a direct tactical shot wins material by exploiting the exposed black king and the loose coordination of the black pieces. In classical chess, these moments often decide the game immediately.
