Commentary for black move 31:
My own feeling is that, yes, Deep Blue -- this version is
stronger than Philadelphia. I cannot make any kind of accurate
determination to its rating today. One game is just not
enough. I need to see a lot more before I can get a better
idea. But I do believe that Deep Blue is playing at
Grandmaster strength and could play even better than most
Grandmasters in certain positions, and worse in other
positions. We'll take a question from this gentleman. And
Garry again clutching his head.
