Chess Endgames - Rook Endings Key Positions

Rook Endings Key Positions

Rook endings are the most common endgames, and three positions decide most rook and pawn against rook cases: in the Lucena position the stronger side wins, in the Philidor position the defender draws, and the back-rank defense saves a rook pawn or a knight pawn. Learn all three, with their mirror images.

Lucena Position

Verdict: White wins.

Goal

Win rook and pawn against rook when the pawn is on the seventh rank, the king stands on the queening square and the enemy king is cut off, by building a bridge that shelters the king from checks.

The idea

The white king stands on the queening square in front of its own pawn, and the black king is cut off along the c-file by the rook on ♖c1. The pawn cannot move until the king steps aside, but the black rook will check the king as soon as it does. The solution is a bridge: the rook goes to the fourth rank and blocks the checks.

Conditions: the pawn is on the seventh rank and is not a rook pawn, the king is on the queening square, and the enemy king is cut off by at least one file.

Technique

1. ♖d1+ pushes the enemy king one file farther from the pawn: ... ♚e7. The cut-off line is now the d-file.
2. ♖d4 builds the bridge: the rook goes to the fourth rank, keeps the cut-off and prepares to block the checks.
3. ♔c7 leaves the queening square. Black checks from a distance with ... ♜c1+.
4. The king walks toward the fourth rank: ♔b6, ♔c6, ♔b5. Each check only pushes it closer to the rook.
5. ♖b4 blocks the last check. The pawn queens next move.

Typical mistake

Trading rooks. A king and a pawn alone do not win against a rook, and here the trade is even stalemate: after 1. ♖a1?? 1... ♜xa1 White has no legal move.

Exercise

White to move. Find the winning method. (Same position, mirrored, with the black rook on the h-file.)

Philidor Position

Verdict: Draw.

Goal

Defend rook and pawn against rook when the pawn is on the fifth rank: keep the white king off the sixth rank and keep the black king on the queening square.

The idea

The black rook on the sixth rank stops the white king from advancing: it cannot step to c6, d6 or e6. The black king stays on the queening square e8, so the pawn cannot queen without the king's help.

Technique

1. Keep the rook on the sixth rank while the pawn is still on the fifth.
2. Keep the king on the queening square, in front of the pawn.
3. When the pawn advances to the sixth rank with e6, the rook goes behind it: ... ♜a1.
4. Check from behind and from a distance. The white king has no shelter, and the pawn alone is not enough.

Typical mistake

Passive rook moves after e6. The rook must go behind the pawn to check from the rear; passive moves such as ... ♜a7 or ... ♜a2 lose.

Exercise

White to move. Win or draw? (Same idea, with the pawn on the d-file.)

Practice

Back-Rank Defense

Verdict: Draw, against a rook pawn or a knight pawn.

Goal

Hold rook and pawn against rook when the pawn is on the a,b, g or h file: keep the king on or next to the queening square and the rook on the back rank.

The idea

The white king stands on h6 with the pawn on g6, and the black king is boxed in the corner: g7 and h7 are covered. The black rook guards the back rank, so White has no mate. If the rook leaves the eighth rank, ♖d8# ends the game.

The method works only against a rook pawn or a knight pawn. Against a bishop pawn or a central pawn, a rook tied to the back rank is a liability.

Technique

1. Keep the king on or next to the queening square, in the corner in front of the pawn.
2. Keep the rook on the back rank and move it only along the eighth rank: ... ♜c8.
3. Meet the checks by stepping between the corner squares: ♖h7+ ... ♚g8, then ♖g7+ ... ♚h8.
4. White can keep checking, but the king and the pawn cannot leave the corner, so there is no progress.

Typical mistake

Leaving the back rank. After 1. ♖d7 the move 1... ♜b1?? allows 2. ♖d8#. The same setup also fails against a central pawn, as the exercise shows.

Exercise

White to move. Win or draw? (The same setup shifted two files to the left, so the pawn is now a central pawn.)

Practice
