This is one of my favorite test positions. This was when Kasparov didnt know how capable programs were and accused the humans of cheating. Kasparov did not think any program would pass up the free a6 pawn, he didnt think any program would play Be4--preventing black from advancing the pawn, and on top of all this Deep Blue opened up the a-file. All of this was too much for Kasparov, of course now he knows he was wrong. (game below)
How long does it take your program to:
1.open the a-file (axb5)
2. avoid this move (Qxa6)
3. block the e pawn with (Be4)

Re: One of my favorite test positions
I love this game. I find it fascinating that Deep Blue was able to find these moves, something that still isn't trivial for many programs today.
Deep Blue's moves in this game are extremely impressive. Given that it wasn't a deep searcher, in the way that today's engines are, it must have had an awfully impressive evaluation function.
Deep Fritz 11 has a hard time with the Be3 move. It takes 21 minutes on my (admittedly not impressive) dual core laptop, analyzing from the position at move 38, to choose Qe3 over Qxa6.

Re: One of my favorite test positions
26.f4! Is a stunning move played by "Deep Blue" Opening of a second
front against a position under pressure can often cause it to collapse
completely, to find this idea is exceptional!
Not many of the top engines today find this move (idea)
Deep Shredder 12 finds 26.f4 !!!
