High Quality Content by WIKIPEDIA articles! The Lucena position is one of the most famous and important positions in chess endgame theory, where one side has a rook and a pawn and the defender has a rook. It is fundamental in the rook and pawn versus rook endgame. If the side with the pawn can reach this type of position, he can forcibly win the game. Most rook and pawn versus rook endgames reach either the Lucena Position or the Philidor Position if played accurately (de la Villa 2008:125). The side with the pawn will try to reach the Lucena Position to win; the other side will try to reach the Philidor Position to draw.
