Just to clarify, do you mean computers playing white vs playing the moves Kasparov made? In other words are there no programs that would play all of the same moves as Deep Blue in this game? Which moves are hard for computers to find? Also, when did Deep Blue leave book in this last game? My view of the match was that I was very impressed with the three games that were draws. Impressed with Kasparov for gaining the initiative and impressed with Deep Blue for its tenacious defense. Only the last game was for me was a dud.
