The main objective in an endgame is to queen a pawn or force your opponent to sacrifice a piece to stop a pawn queening.
This week’s problem illustrates that theme.
In an endgame, there are often more flank pawns left on the board than centre pawns. The centre pawns tend to be exchanged more often than the other pawns.
When it comes to fighting against a passed Rook’s pawn, the Knight is the worst piece. Despite appearances in the diagram, the black Knight will be unable to stop a White pawn from queening, provided that White finds the right sequence of moves. How does White win?
The solution to last Monday’s problem is that White plays 1 d5 Kxd5 2 h3 Ke6 3 Kd4 Kd6 4 h4 and Black is in Zugzwang.
