under promotion Chess Puzzles
Under promotion is when a pawn reaches the last rank and is promoted to a piece other than a queen, usually a knight, rook, or bishop. It is a rare but powerful tactical idea because the new piece can create a specific threat, avoid stalemate, or give check that a queen would not. In practical play, under promotion often appears in endgames and forcing combinations where the exact piece matters more than raw material value.
To spot under promotion, look for positions where promoting to a queen fails because it stalemates the opponent, misses a check, or allows an immediate tactical resource. Ask whether a knight fork, rook check, or bishop move from the promotion square wins faster than a queen would. In your games, calculate the promotion move as a choice among all four pieces, not as an automatic queen promotion.
