I just looked at the game. With 14...Qd7, Black would have been about equal.
Trust me, if your rating is above about 1400 you should be able to get a winning
position every time against this machine by move 14. You gave it way too much
respect. I doubt that it can see 4 ply in the middlegame. I would not be
surprised if its nps was something like 50 (and with a terrible search
algorithm).
