Learn How to Promote: Mate in 2
This chess endgame puzzle is a classic example of how a passed pawn can decide the game instantly when the enemy king is boxed in. Even though White appears to be ahead materially, the real story is tactical: the position contains a forcing sequence that turns a promotion threat into a direct mate. In classical chess, these patterns often arise when a queen sacrifice or exchange clears the path for a new queen to appear with checkmate.
