Four Knights Game Double Spanish Puzzle (Rated 1180): Win Material — Decisive Tactical Fork
This middlegame puzzle shows how a single active rook can force a winning sequence by exploiting king safety and loose pieces. Black’s pressure on the e-file creates a direct tactical problem for White, whose back rank and king coordination are already stretched. The key idea is attraction: a capture lures a defender onto a vulnerable square, after which the king is exposed to a forcing check and a decisive material gain. It is a classic example of converting activity into concrete advantage.
