Nimzo Indian Defense Fork Beginner Puzzle (Rated 1179): Win Material — Fork Tactic
This middlegame puzzle shows how a single tactical sequence can turn a balanced position into a decisive material win. White’s king is safe, but the pieces are slightly loose and the coordination around the kingside can be exploited. Black’s active bishop creates a tactical target and the resulting pressure opens the way for a forcing queen move. The key idea is to use forcing moves to win material while keeping the opponent’s king tied down.
