Kings Indian Defense Accelerated Averbakh Variation Puzzle (Rated 1173): Fork — Decisive Material Gain
This middlegame puzzle is built around a forcing knight jump that creates a fork against the enemy king and major pieces. The key idea is to use check to drag the king into a worse square, then win material with a follow-up capture. Positions like this often arise when one side has active pieces and the opponent’s king is slightly exposed. In classical chess, these tactical shots can turn a small edge into a decisive material gain very quickly.
