What a disaster! Objectively, Deep Blue had not played well enough overall in the first five games of its match with Garry Kasparov to pose a real threat to the world champion, but it had certainly served up a sufficiently weird cocktail of mindlessness and brilliancy to make him very uncomfortable indeed. His display in the final game bore all the signs of a man whose equanimity had been shattered.

At the end, after 19...Nb4 20.Qe2, followed by d5 or cxb5, or 19...bxc4 20.Qxc4 Nb4 (20...Kb7 21.Qa6 is mate) 21.Re1 Black cannot long withstand the White attack. The real blunder, however, was 7...h6? which is a known trap in this position. Kasparov simply forgot to play 7...Bd6 first.

It was the fifth game of the match, however, that really stifled Kasparov's spirit. Deep Blue was Black in the diagram position, (after White's 39th move) and saw that its g-pawn was doomed. Play continued 39...Ne4 40.Nxg7 Rd1+ (Nxg3 loses to Ne6+) 41.Kc2 Rd2+ 42.Kc1 Rxa2! 43.Nxh5 Nd2! 44.Nf4 Nxb3+ 45.Kb1 Rd2 46.Re6 c4! 47.Re3 Kb6!! 48.g6 Kxb5 49.g7 Kb4! and after 50.g8=Q Black has a draw by perpetual check with the rook. And if White had played 47.Re4 instead of Re3, we see another remarkable draw after 47...Kb6 48.Rxc4 Kxb5 49.Rc7 Kb4! 50.Rxb7+ Ka3 51.Rxa7+ Kb4 when White again cannot prevent a perpetual check.
