Chess: Dabbling with the deep

DEEP Thought II is on its way. The world's strongest chess computer, in its previous incarnation as Deep Thought, won games against grandmasters and took first prizes in strong tournaments, but even analysing at two million positions a second it never quite looked world class. Now, with new hardware being made and an improved program ready to run, its speed of thought could be increased by up to tenfold.

Recent tests have seen a combination of the old and new Deep Thoughts playing under the name Deep Blue, or, when playing in Scandinavia, Nordic Deep Blue. Today's game, played in a match against top Danish players, shows that apparently deep positional ideas can flow from brute force calculation at four to five million positions a second. Black's middle-game play from move 20 to 40 is an examplary display of how to nullify the effect of a threatening pawn majority. The mating net woven at the end is pretty too, but trivially easy for a brute of this power.
