{ The Saavedra position is one of the best-known chess endgame studies. It is named after the Spanish priest Fernando Saavedra (1849–1922), who lived in Glasgow during the late 19th century. Though not a strong player, he spotted a win involving a dramatic underpromotion in a position previously thought to have been a draw.
This is among a minority of positions where king and pawn can win against a king and rook, and one of the most famous examples of underpromotion in chess. It is also a rare example of a player being famous for a single move.
