Yes, this line doesn't seem to be clearly lost for black and 22.Qh5 Bxc6 23.dxc6
Rg6 seems to be a draw although it looks dangerous on first sight.
The question is if there exists something better than 19.Nc6.
What did Alex Kure write? :)
"It is clear to me. This line ist lost. Neither 19...Qa5 nor 19...0-0-0 nor
18...Nd7 will prevent black from loosing.
It is all theory! The fact, that you don't know the theory of this line does not
imply that it is not clear."
"It is not relevant if you need some or more time to convince yourself if this
line is really lost for black. Nobody cares!
I convinced myself long ago by analysing this line to the bones for more than 15
years!
So I will give you as much time as needed to find out for yourself ;-)
And I will be glad to hear from you that you found a variation where black does
not loose."
I can easily get a draw against Fritz 8 in that line.
But of course I am not satisfied with a draw against Fritz :)
Maybe we should put forward this line to Garry.
He IS happy to draw the machines.
