The Lucena position is a standard rook-endgame study. Learning the plan is more useful when you also understand what the defender is trying to prevent.
What to do
Open a verified Lucena lesson, identify the placement of both kings and rooks and practice the main method. Then play the defensive side against the same setup.
A mistake to avoid
Do not call every rook-and-pawn ending Lucena. Check the defining arrangement before applying a remembered technique.
A detail worth checking
Rebuild the position from memory only after learning it accurately. Then compare your reconstruction with the lesson. Incorrectly placing one rook can turn a useful memory exercise into practice of the wrong ending.
Try this practical check
After completing the lesson, explain the purpose of each rook move in ordinary words. Repeat later without viewing the solution and note the first point of uncertainty.
