He gives 16.Bxh7+ 16...Kh8! "After 16...Qxh7 17.Qxh7+ Kxh7 18.Rh1+ White can either raise Black's light-squared blockade with Rh1-h4! or force his opponent to play f7-f5, which does not look good from the positional standpoint." the position after 16...Qh2 17.Bxh7+ Qxh7 18.Qxh7+ Kxh7 19.Rh1+ is the same position except g-pawn on g3 instead of g2 (makes no difference). this position is slightly favourable for white and there is no danger to lose without a big blunder.
