Learn How to Trap a Piece: Endgame Advantage
This chess endgame puzzle is about converting a small tactical edge into a decisive material gain. The key idea is to use pawn play to restrict an active enemy piece, then open lines so that the piece has no safe retreat. In simplified positions, even a single trapped knight can swing the evaluation because activity and king safety matter so much. Look for forcing pawn moves that create new threats while also taking away escape squares.
