In this week’s position, White is losing.
He tries one last trick with 1. g4.
Even in supposedly very simple positions, you need to concentrate to the end.
Black played 1…hxg4 after White played 1. g4. Can you see how White now draws the game?
What should Black have played on his first move to win the game?
The solution to last Monday’s problem is that White plays 1. h4 Kg4 2. Kg6! Kxh4 3. Kf5 and he can get back in time to stop the Black pawns.
