Kings Indian Defense Averbakh Variation Puzzle (Rated 1141): Win a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of tactical pressure turning into decisive material gain. White’s queen is active, Black’s king is slightly exposed, and one loose major piece creates the chance to win big material with a forcing sequence. The key idea is to use a checking move to pull the king into a vulnerable square, then capture the overloaded rook on the corner. It’s a strong example of how a short combination can outweigh a material deficit.
