I left you with a pawn ending puzzle taken from lichess.org on Monday.
Here’s how it plays out. Click on any move for a pop-up window.
The two important points to note is that 3. Kc4! is the only way to win (Kd3? draws), and that, in the main line, 5. Kd3! wins, but Kd4 doesn’t. Basic knowledge of Q v P on the 7th rank (which everyone should have) is helpful here.
Don’t forget to practise your pawn endings regularly!
