Lucena Position is a classic winning rook endgame in which one side has a passed pawn that has reached the seventh rank, along with active king and rook placement.

Basic Idea

• The attacking side uses the rook to prevent side checks against its king.
• Then, with the idea of building a bridge, it brings the king out from in front of the pawn.
• The pawn advances safely to promotion.

The Lucena is one of the most fundamental winning techniques to know in rook endgames.
