Test your chess: daily chess puzzle # 158

White to play and win

S Galleid v K O'Sullivan 1981

Solution

After yesterday's toughie, today's is more straightforward, just an exercise in calculation to see if the obvious sacrifice 1 Bg6+! wins. It is not too hard, but nor trivial, to see that it is.

Firstly, if black doesn't play 1…Kg6, say by playing 1…Ke7, then 2 Be8 and the material advantage will tell. So 1…Kg6 2 Qh6+ Kf7[] 3 Qh7+ and either the Bh8 drops off (after 3…Kf8) or 3…Bg7 4 Nh6+ and it still falls (4…Kf8 5 Qg8+ etc).
