Learn How to Promote: Pawn Promotion
This puzzle is a classic example of how an advanced pawn can decide a chess endgame instantly. The key idea is that a passed pawn on the seventh rank can become a direct mating threat when it reaches the last rank. In positions like this, promotion is not just about winning material — it can also create a forced checkmate if the new piece controls the enemy king’s escape squares. Always look for promotion first when a pawn is one step from queening.
