Learn How to Promote: Advanced Pawn Coercion
This puzzle shows how an advanced pawn can force the opponent into a losing defensive choice. The key idea is promotion pressure: when a passed pawn reaches the last rank, it can become a new queen and immediately create threats that the enemy king cannot safely ignore. In this middlegame-to-endgame transition, king safety matters more than material, and the attack is built around forcing moves rather than slow improvement.
