Anti Lemming Puzzle (Rated 1402): Fork — Decisive Material Gain
This middlegame puzzle shows a classic tactical fork where an active knight jumps into the enemy camp and attacks two major pieces at once. The position is built around king safety problems, loose back-rank coordination, and a passive queen-side setup. In practical terms, White’s pieces are ready to exploit hanging material and weak squares, turning development into a direct tactical gain. The key idea is to use piece activity to create a forcing sequence that wins material decisively.
