{[%mdl 2] The game between two grandmasters in the last round mostly ends to a draw. But not this time. Wells was sharing the first place before the last round with Spraggett and Benjamin, and could try to get a clear first, after the quick draw between two others.On the other hand, Rowson, had half a point less, and actually had nothing to lose in this game!} 1. d4 d6 2.

Any human Any human under such assault by a world champion would be staring at his own king trying to figure out how to get away. Instead, Deep Blue ignored the threat and quite nonchalantly went hunting for lowly pawns at the other end of the board. In fact, at the point of maximum peril, Deep Blue expended two moves - many have died giving Kasparov even one - to snap one pawn. It was as if, at Gettysburg, General Meade had sent his soldiers out for a spot of apple-picking moments before Beckett's charge, because he had calculated that they could get back to their positions with a half-second to spare. In humans, that is called sangfroid. And if you don't have any sang, you can be very froid. But then again if Meade had known absolutely - by calculating the precise trajectories of all the bullets and all the bayonets and all the cannons in Pickett's division - the time of arrival of the enemy he could, indeed, without fear, have ordered his men to pick apples. Which is exactly what Deep Blue did. It had calculated every possible combination of Kasparov's available moves and determined with absolute certainty that it could return from its pawn-picking expedition and destroy Kasparov exactly one move before Kasparov could destroy it. Which it did. It takes more than nerves of steel to do that. It takes a silicon brain. No human can achieve absolute certainty because no human can be sure to have seen everything. Deep Blue can."} Ne5 30. Qd5 f3 31. g3 Nd3 {To give you an impression of the volatility of the position let us take a look at some of the lines Kasparov had to consider:} (31...
