Kf2 0-1 Aren't other programs of today playing the same winning moves as Deep Thought here? Starting with 22. ... Qe3+ and ending with 31. ... a4(Rd8+ looks like a direct transposing of moves would be considered as good if followed by the a4 advance). Or is the point that Deep Thought ran these lines deeper, which I don't doubt that it did. I still think that the best demonstration of the project's strength are games 2-5 of the second match with Kasparov. I'm still guessing that these games really wore Kasparov down. These were great games and games 3, 4 and 5 showed how extremely difficult it was for the best chess player on the planet to convert his advantages in these games to wins.
