| The square rule|
It's the most basic rule for the quick computation of pawn endings. In this combination the key is putting something on the path of the black King so that it has to stop the run.
| Three against three|
A classic problem that sometimes appears in real endings.
This is the basic position of the King+Pawn vs King ending. It's fundamental keeping the opposition, otherwise the game is lost.
| Canberra ending|
This well-known ending shows how sometimes it's necessary to promote to a minor piece to win a game.
| The King fights the Queen|
This is one of the rare cases in which a King and a Pawn can draw a game against the powerful opposite Queen.
