King's Indian Attack Puzzle (Rated 815): Win Material — Tactical Fork
This middlegame puzzle is about converting king safety into material gain. Black’s active knight jumps into the attack with check, forcing the white king to move and exposing loose pieces. The key idea is that the check is not the end goal; it is a tactical refutation that wins time and creates a fork on the next move. In positions like this, a single forcing move can turn an exposed king into a decisive advantage.
