Learn How to Spot Mate in 1: King Safety
This middlegame puzzle comes from the Bird Opening, specifically a From's Gambit structure where king safety breaks down fast. White has a huge material edge, but the real story is the exposed king and the overloaded dark-square defenses around it. When the enemy king is boxed in and key escape squares are controlled, even a position that looks materially won can end immediately. The lesson is to always scan for direct tactical shots before choosing a quiet conversion.
