Learn How to Trap a Piece: Endgame Equality
This chess endgame puzzle is built around a trapped piece motif: one side has a large material edge, but the opponent can still create practical chances by targeting loose pieces and forcing simplification. The key idea is that even in a classical chess position, activity and piece coordination can matter more than raw material for a few moves. Here, the defender must notice the vulnerable rook and the tactical pressure on the back rank and diagonals before the position collapses into a winning material sequence.
