Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the English Opening and shows a classic tactical refutation where active pieces punish loose coordination. White appears to have the better material, but the position contains hidden tactical liabilities: an exposed king, an undefended queen-side setup, and pieces that can be hit with tempo. The key idea is to recognize when a forcing sequence can overturn a large static advantage by winning material and improving piece activity at the same time.
