The opposition is a position where two kings face each other with one square between them and the player who does not have to move holds the advantage. In king and pawn endgames, winning the opposition lets your king step ahead of the enemy king and escort a pawn to promotion.
What the Opposition Means
Because kings cannot stand next to each other, a king facing the other with a single gap controls the squares in front of the rival. The side that must move has to give way. This is a kind of zugzwang, where having to move is a disadvantage.
- Direct opposition: kings on the same file or rank with one square between.
- Distant opposition: same file or rank with an odd number of squares between, such as three or five.
- Diagonal opposition: kings on the same diagonal with an odd number of squares between.
How to Win the Opposition
- Count the squares between the kings. If it is your move and the gap is an even number, you can often step to make it odd and take the opposition.
- Prefer to take direct opposition when you can reach it by a single king step.
- Keep waiting moves in mind. If one side has a spare pawn move, the other side may lose the opposition by force, so count those tempo moves too.
- Aim your king in front of your pawn. A king on the sixth rank ahead of its pawn often wins, though the exact details vary with the pawn’s file.
- Check for the edge-pawn exception. A rook pawn is hard to win with, because the defender can hide in the corner.
A Simple Example
Put a white king on e6 and a white pawn on e5 against a black king on e8: White wins whoever is to move, because the king already stands on a key square. Now pull the white king back to e5 with the pawn on e4, against a black king on e7. With White to move, Black holds the opposition and the game is drawn; with Black to move, the king must give way and White wins. This is why counting tempi matters more than memorizing a single diagram.
| Situation | General guidance |
|---|---|
| Your king ahead of the pawn | Usually good chances to win |
| Kings face each other, you to move | You may need to give way |
| Rook pawn | Often drawn if the defender reaches the corner |
Practice Tips
- Set up simple positions against a friend or a training tool and play them out.
- Work out the answer by counting before you move any piece.
- Study the key squares of a pawn: a king standing on one of them usually forces promotion.
FAQ
Is the opposition useful outside pawn endgames?
Mostly in king and pawn endings, though the same idea of tempo and forced retreat appears in other endings too.
What if I miscount?
Try moving the kings one step at a time on a board. Seeing who runs out of useful moves first is often clearer than counting in your head.
The Short Version
The opposition lets you push the rival king aside. Count the squares and the spare moves, put your king in front of the pawn, and watch for rook pawn draws. Practice small positions until the counting feels automatic.
