A valuable resource to help us save endgames is stalemate.
In this week’s problem, White is in big trouble. He has an extra pawn, but the good news stops there. The Black King is so active that it will be able to take all of White’s pawns.
However, White can still draw the game. How does White draw? He has to stalemate the Black King , eventually, to save the game.
The solution to last Monday’s problem is that White plays 1 f4+ Ke6 2 f5+ Ke5 3 Bg6! fxg6 4 h7! Nxh7 5 fxg6 and the Black Knight is helpless against the passed pawn.
