Learn How to Deflect: Decisive Material Gain
This classical chess puzzle comes from the Queen's Gambit Declined and shows how a long forcing sequence can turn a small tactical edge into decisive material gain. The key idea is deflection: a defender is lured away from an important square or duty, and once that piece is overloaded, the position collapses. In the middlegame, such tactics often punish loose coordination, especially when the king is still in the center and pieces are pinned or trapped.
