Rook Endgames: The Lucena and Philidor Positions
The two positions every chess player should know in rook endgames: how to win the Lucena by building a bridge, and how to draw the Philidor.
Rook endgames are the most common endgames in chess. Since rooks are usually the last pieces traded, roughly half of all endgames feature rooks. As the saying goes, "all rook endgames are drawn", which isn't true, but it captures how tricky they are to win. Two positions form the foundation of all rook endgame knowledge: the Lucena, which is a win, and the Philidor, which is a draw.
The Philidor position: how to draw
Imagine White has a king, a rook and a pawn, and Black has a king and a rook. The black king stands in front of the pawn. White's pawn has not yet reached the sixth rank. Here is Black's drawing method:
- Put your rook on your third rank, which for Black is the 6th rank. This stops White's king from advancing to the sixth rank in front of the pawn.
- Wait there. Move the rook back and forth along that rank. White can't make progress without pushing the pawn.
- When the pawn advances to the sixth rank, send your rook to the far end of the board, White's first rank, and check the white king from behind. Now the pawn on the sixth rank no longer shelters the king from vertical checks, and the king can't hide in front of it.
The most common mistake is retreating the rook to your own back rank too early. Then White's king walks forward to the sixth rank and the defence collapses. Third rank first; first rank only after the pawn advances.
The Lucena position: how to win
Now the winning side. White's pawn is on the seventh rank, White's king is on the queening square in front of it, and the black king has been cut off by at least one file. Black's rook prevents White's king from getting out in front of the pawn. White's winning technique is called building a bridge.
A typical setup: White king on d8, pawn on d7, White rook on f1 cutting off the black king on g7, and Black's rook on c2 stopping White's king from stepping out to the c-file.
- Rf4! White moves the rook to the fourth rank. This is the key move; it will shortly be used as a shield.
- Black waits, for example with Rc1.
- Ke7: White's king comes out. Black checks: Re1+.
- Kd6, and Black checks again: Rd1+.
- Ke6, and after Re1+, Kd5. Black checks once more, Rd1+...
- Rd4!: the rook steps in front of the king and blocks the check. That's the bridge. The checks are over, and the pawn will promote.
The details vary depending on where the pieces are, but the idea is always the same: put your rook on the fourth rank, walk the king out, and use the rook to block the checks.
Rules of thumb
- Rooks belong behind passed pawns, your own and your opponent's. Behind your own pawn, the rook gains activity as the pawn advances; behind your opponent's, it gains activity as the pawn advances too, while staying ready to capture.
- Activity beats material. An active rook is often worth more than a pawn. A passive rook tied to defending a pawn usually loses.
- Cut off the enemy king. A rook on a file between the enemy king and your pawn can win positions that would otherwise be drawn.
- Check from a distance. Checks from close range let the king approach and escape. Long-range checks keep the defending rook safe and the king busy.
When an extra pawn isn't enough
Many rook endgames with an extra pawn are drawn. Common examples: all the pawns on one side of the board (three pawns against two on the kingside is often a draw), or a rook's pawn with the defending king in front of it. If you're defending, aim for these. If you're attacking, keep pawns on both sides of the board to stretch the defence.
Practise it
Set up the Philidor and Lucena positions with pass-and-play and play them through until you can do both from memory. Then play the computer from the same positions and try to beat Max level: it will defend perfectly, so if you can win the Lucena against it, you really know it.
