Learn How to Trap a Piece: Winning Material
This middlegame puzzle comes from the Bogo-Indian Defense and shows a classic tactical refutation based on a trapped piece and loose back-rank-style coordination. White’s position looks active, but the queen and rook activity create tactical targets that Black can exploit. The key idea is to use pressure on undefended squares and force the opponent into a sequence where material is won cleanly rather than relying on long-term strategy. It is a good example of how static material can be overturned by concrete tactics.
