A pawn on the seventh rank is worth more than most pieces — if it gets to the eighth. Promotion puzzles are about making that happen by force: clearing the path, winning the race, or sacrificing everything else because a new queen pays for it all. Solve the featured real-game puzzle below, then train promotions in the trainer at your level.
The signature theme is the breakthrough: a wall of pawns faces a wall of pawns, and a sacrifice — sometimes two — punches a single runner through while the defender's captures pull his pawns out of the race. Add escort technique (rook behind the passer, king shouldering the enemy king away) and deflection of the blockading piece, and you have most of the genre. Race positions reward exact counting: whoever queens first, or queens with check, takes everything. Count tempi, not hopes.
Sometimes the new queen loses to a skewer or walks into stalemate, and the winning move is a knight that arrives with check, or a rook or bishop chosen precisely because it does NOT give stalemate. Real games produce these more often than you would think. The promotion glossary entry covers the rule and its edge cases.
Promoting to a knight, rook or bishop instead of a queen. The knight is chosen for its unique powers — often arriving with an immediate fork or check no queen could give; rook and bishop are chosen almost exclusively to avoid delivering stalemate that an automatic queen would cause. Rare, but game-deciding when it appears.
A forcing pawn sacrifice (or two) that converts a blocked pawn group into one unstoppable passed pawn — the defender's captures drag his own pawns off the files they needed to guard. Breakthroughs win races by force and are among the most satisfying calculations in chess, because the material invested comes back with a crown.
Count each side's tempi to promotion — including any checks along the way, because a queen that arrives with check wins the race even one tempo behind. Use the square-of-the-pawn test for whether a king catches a runner, and remember the first new queen often wins the second one with a skewer along the promotion rank.
