Clear

It is not clear for me.

19...Qa5 was only one option and black has alternatives like 19...0-0-0
or 18...Nd7

I do not play this line and it is clearly mistake to allow a popular line when
you did not analyze this position for many hours.

I also do not think that you practically need to be sure about win to play the
line and it is enough if you are sure of at least eqaulity when in all the lines
that you checked you found a clear advantage for white.
