Learn How to Trap a Piece: Tactical Refutation
This middlegame puzzle is about recognizing when a piece has wandered onto the edge of the board and can be restricted by simple, forcing moves. The key idea is not a flashy attack, but a tactical refutation that wins material by limiting escape squares and coordinating your pieces. In classical chess, these positions often look calm, yet one accurate move can turn a loose piece into a long-term liability.
