Here's a brief description on Calsen's explanation about "The Rule of the Square". The Rule of the Square is used to determine whether or not a passed pawn can queen when it is not supported by its own king and the enemy king is chasing it. The idea is shown by the diagram on the right: One side of the square is the line that extends from the pawn to the square on which it queens.

If the enemy King is on one of the crosses the game is over for you. Queening is just a dream!

Hope you like this explanation and be mindful about your enemy King's position in the endgame.
