Let's see... 37...Kh8 ist # in 3.

After 37...Kg8, Goliath light 1.5 immediatly wants to play 38.Bh7+ and stays
with a 0.00 evaluation, expecting KxB. After 37...Kg7, he again shows 0.00
constantly planning 38.Qxd4+ Kxg6...

There seem to be a lot of side variations, i.e. if black continues to avoid KxB.
I don't feel quite capable of a complete analysis.
