Sicilian Defense Keres Variation Puzzle (Rated 996): Crush with a Fork — Decisive Material Gain

This middlegame puzzle is built around a crushing fork that targets the enemy king and a major piece at the same time. White’s active knight jumps into the heart of the position, creating a forcing check that also exposes a trapped queen and weak king safety. The key idea is that tactical activity can outweigh static concerns when the opponent’s king is vulnerable and their pieces are poorly coordinated. Once the forcing check lands, the follow-up wins material cleanly.
