Winning with Just Kings and Pawns
From Good to Great: Pro-Level Tips
The Concept of Opposition
Opposition is when the two kings stand on the same file with one empty square between them. The player whose turn it is NOT to move has the opposition, and can force the other king to give way. Mastering this concept is essential to winning pawn endgames.
The Rule of the Square
To quickly determine if a king can catch a passed pawn, use the "Rule of the Square." Draw a square from the pawn's current square to its promotion square. If the enemy king can step into this square on its turn, it can catch the pawn. If it cannot, the pawn will promote.
A Move That Made History: Reti Endgame Study, 1921
This is one of the most famous chess studies of all time. It seems impossible for the white king to both catch the black passed pawn on the a-file and support its own pawn on the h-file. However, the solution is a brilliant king maneuver that moves diagonally, threatening to do both simultaneously. It perfectly illustrates that in chess, the shortest distance between two points is not always a straight line.
