Pawn Promotion Puzzle (Rated 696): Promote — Pawn Race
This chess endgame is decided by a promotion race between advanced passed pawns. Material already favors Black, but the key issue is timing: each side is close to creating a queen, so a single tempo can determine the result. Strong endgame technique means comparing promotion squares, checking whether the new queen arrives with tempo, and identifying which pawn must advance immediately. The winning plan uses the most urgent passed pawn while preserving control over the opponent’s promotion threat.
