Astonishing positional suicide -- few, if any, humans would ever play 21.b4,
entombing the queen. Of course, Tiger could afford to open the game in any way
it pleased after that. It would be interesting to see if the lack of interest in
liberating the queen is duplicated by many programs; correct or not, I would
have been so concerned about this offside post that I would have played 17.Qe1
immediately.
