Lucena Position — Win the Rook Endgame
Objective: Task goal: win the rook endgame and promote the passed pawn.
Position and task condition
The classic Lucena position. White has a pawn on the seventh rank, but promotion is not automatic: the white king blocks the promotion square while Black's rook is ready to give repeated checks. Find the plan that lets the king escape the checks and safely guide the pawn to promotion.
