I know tree his game is old...
The board was incorrectly shown as Nb3, move 10.Nc3 was made (move numbers were also incorrect).
Might have had an effect on the immediate results after 10...Wh6 and White had noticed he could take the bishop.
Of course, Black probably wouldn't have played Wh6 at that point either.
I don't know. I rarely analyze games deeply (except for Daily Chess with an analysis board). I kind of play by gut. If I actually focused and did the work, and took the time, I would probably be really good, but I go too fast.
