Commentary for white move 16:

JOE HOANE: That's right. The point I wanted to make is that, you know, over the last six months, Deep Blue has gone from playing chess sometimes to playing chess all the time. Or nearly all the time. Of course it makes strange moves. It has weaknesses and it has strengths. But weaknesses aren't too weak anymore, in terms of what it knows about chess. 15...Nc7.
