King's Indian Defense Other Variations Puzzle (Rated 1259): Win Material — Tactical Refutation

This middlegame puzzle comes from the King's Indian Defense and revolves around a tactical refutation based on a forcing queen check. White’s queen is active, the black bishop on b2 is overextended, and the position contains hanging pieces on both sides. The key idea is to use tempo-gaining checks to expose the king and then collect material while the opponent’s pieces remain awkwardly placed. In practical terms, this is a classic advantage-fork pattern where activity matters more than the raw material count.
