Kings Indian Attack Keres Variation Puzzle (Rated 1443): Win the Queen — Decisive Material Gain

This middlegame puzzle is about converting a tactical edge by exploiting a loose piece and the pressure on the queen. White already has a development lead and stronger coordination, while Black’s queen is active but overextended. The key idea is to use a forcing move that improves piece activity and creates a direct tactical problem for the queen. In positions like this, the best continuation often comes from simplifying into a winning material sequence rather than searching for a flashy attack.
