Did you try to generate a tree with the computer to prove that 17...Qd5 is
really the best move?

It is clear that after 19.Nb6 white is losing but the question is if white has
no good alternative before(for example 18.f3)

I believe that computers can avoid the blunder of taking material at long time
control but they may reject 17...Qd5 because of lines that white does not play
19.Nb6 at long time control.
