programmers analyzed the line Qb6 Qe7 and found nothing convincing for black.
I can only say that I believe that Qb6 was the best move.

I believe that the position was equal after Deep blue's moves and kasparov
blundered later.

People who claim that white is winning should post their win against the top
programs without playing Qb6 if they want to convince someone except themselves.
