1997 Game 2, Deep Blue vs. Kasparov
In this game Kasparov accused IBM of cheating, a claim repeated in the documentary Game Over: Kasparov and the Machine. Kasparov eventually resigned, although post-game analysis indicates that the game could have been drawn. The game started with the Ruy Lopez opening Smyslov Defence variation.
Kasparov missed the fact that after 45... Qe3 46.Qxd6 Re8, black can force a draw by perpetual check. His friends told him so the next morning. They suggested 47.h4 h5!, to result in a quick ending. The reference does not mention 47.Qc7+ (or Qd7+) as a way for white to further delay the drawn ending.
The game became subject to a forced draw instead of a probable win for Deep Blue when it moved 44.Kh1 instead of an alternate move of its king. Regarding the end of game 2 and 44.Kh1 in particular, chess journalist Mig Greengard in the Game Over film states, "It turns out, that the position in, here at the end is actually a draw, and that, one of Deep Blue's final moves was a terrible error, because Deep Blue has two choices here. It can move its king here or move its king over here. It picked the wrong place to step." Another in that film, four-time US champion Yasser Seirawan, then concludes that, "The computer had left its king a little un-defended. And Garry could have threatened a perpetual check, not a win but a perpetual check." (SOURCE WIKIPEDIA)
