Chess Puzzle of the Week (172)

Vasily V Smyslov 64 #39 1936
White to play and win

I’m currently reading The Life and Games of Vasily Smyslov Volume 1 by Andrey Terekhov (Russell Enterprises Inc). My review will be published on British Chess News shortly.

Smyslov was renowned for his endgame play, and composed studies throughout his life. This one was composed when he was only 15.

As always in endgame studies, there’s good news and bad news. The good news is that you’re a knight ahead and threatening mate in 2 by promoting the g-pawn. The bad news is that you can’t prevent Black promoting with check next move.

How can White win from this position?

Come along to the Adelaide tomorrow evening and show me how!
