Pseudo Queen's Indian Defense Puzzle (Rated 1018): Win Material — Tactical Refutation

This middlegame puzzle is about spotting a tactical refutation when an enemy piece becomes overextended. White has active pieces and a clear target on the kingside, while Black’s advanced bishop and knight create tactical pressure but also tactical liability. The key idea is that a lower-value piece can capture the attacking bishop, forcing a sequence that simplifies the position and leaves White with the better material balance. In practical classical chess, these moments often decide the game immediately.
