Shouldering is a king maneuver in which one king steps into a square that cuts the opposing king off from a pawn or from the route toward it. Shouldering is a king maneuver in which one king steps into a square that cuts the opposing king off from a pawn or from the route toward it, so the opponent cannot approach. The word comes from the picture of leaning a shoulder into someone to keep him from the ball. Kings can never touch, so the idea is positional: your king steps onto a [square](https://georgelichess.com/glossary/square.md) beside the path the enemy king needs, covering the squares in front of it, and the opponent has to retreat or take a longer way around. Shouldering matters most in races. When a [passed pawn](https://georgelichess.com/glossary/passed-pawn.md) is running and a king is chasing it, a king that gets in the chaser's way without losing time can win a race that the [rule of the square](https://georgelichess.com/glossary/rule-of-the-square.md) would otherwise award to the chaser. It also helps a king keep an enemy king away from a loose pawn, or away from a key square in front of a pawn. To spot a chance, trace the route the enemy king wants and ask whether your king can reach a square beside that route in time, ideally with a tempo to spare. Count the steps along [diagonals](https://georgelichess.com/glossary/diagonal.md), since a king moves diagonally as quickly as straight. A common [mistake](https://georgelichess.com/glossary/mistake.md) is to run directly at the pawn from behind, so the opponent gets the shoulder instead. Another is to aim for a shouldering square next to the enemy king, which is illegal because kings may never stand on adjacent squares. ## Example position White to move wins only with 1.Kc6, shouldering the black king away from the corner. After 1...Kd8 2.Kb7 the king seals a8, b8 and c8, and the a-pawn walks home. Pushing 1.a5 first lets Black's king reach the corner and draw. Position (FEN): `8/4k3/8/3K4/P7/8/8/8 w - - 0 1` Also worth reading is [Diagonal opposition](https://georgelichess.com/glossary/diagonal-opposition.md). Diagonal opposition is the standoff in which the two kings sit on the same diagonal with exactly one empty square between them, so the king that has to move must give ground. Also worth reading is [Reti maneuver](https://georgelichess.com/glossary/reti-maneuver.md). The Reti maneuver is a king walk that heads for two goals at once, usually stopping a distant passed pawn while also supporting the king's own pawn, so the opponent cannot defend against both threats.
