Rapport Jobava System Fork Beginner Puzzle (Rated 1155): Win Material — Fork Tactic
This middlegame puzzle is a classic example of tactical pressure turning into a decisive material win. Black’s active pieces coordinate against White’s king and loose pieces, creating a forcing sequence that wins the exchange and leaves White unable to untangle. The key idea is that one tactical shot can exploit a pinned or trapped piece while also attacking the king, making the defense collapse. In practical classical chess, these motifs often appear when one side’s pieces are active and the opponent’s king is still exposed.
