Learn How to Trap a Piece: Endgame Tactics
This chess endgame puzzle is built around a trapped piece and a decisive tactical gain. White’s rook is active, but Black’s knight has invaded the kingside and can be forced into a vulnerable square. In classical chess, active pieces and king safety often matter more than raw material, and here the side to move must use that imbalance to create a winning combination. The key idea is to recognize when a piece looks active but is actually overextended and vulnerable to a forcing sequence.
