This may have been posted at some other time but it is interesting. Modern engines in particular believe that Black is a bit better off here and they typically want to play 20.Qe2? White has a clear winning line after 20.Rxg7!, for example:

20.Rxg7 Rxg7 21.Qxh6 Rg8 22.Qh7 Ne7 23.Nf3 Kd7 24.Bg5 Re8 25.g7 Qd8 26.Bg6 Rg8 27.Rc1 b6 28.b4 axb4 29.axb4 Na6 30.Bd3 Nc7 31.Bxe7 Kxe7 32.Rxc7+ Qxc7 33.Qxg8 Qc1+ 34.Kf2 Qf4 35.Qh7 Ra2+ 36.Be2 Qf7 37.g8=Q 1-0
