I know that Kasparov and his defenders regularly give the idea that Deep Blue only played against Kasparov, but that's really not true.
I recommend reading this book which features the other side of the story, it's interesting and informative:
Except that a DB prototype lost to Fritz in 1995 - but that's what a prototype is for.
As for the book: thanks but I'm not interested, I believe Hsu wrote better stuff than that.
What do you recommend by Hsu? All I have read is that book and some article about Deep Blue's internals.

Re: Performancerating of Kasparov and Deep Blue in their mat
Of course it did beat the calculators at the time, that's obvious. I can also say my old 386 would "beat the crap" out of a 6502, that doesn't really impress me.rbarreira wrote:It didn't just beat them, it beat them very convincingly and it improved gradually to a point where it became possible to take on Kasparov and possibly win (which it did).

I have my doubts about whether it was good enough to beat a world champion. I believe it was not.
Some of his technical papers?What do you recommend by Hsu? All I have read is that book and some article about Deep Blue's internals.

3 ACM tournaments plus other tournaments and matches. There are also some which are not listed there, such as a match in Denmark against the Danish National Team and a match against a Chinese WGM. Then Deep Blue Jr also played a computer tournament in 1995.

Thank for appreciating my work.Lyudmil Tsvetkov wrote:Hi Jens.
Thanks for your effort!
50 elo difference in performance in Deep Blue's favour when it actually lost the match in 1996 is obviously wrong.
200 elo difference in performance in Deep Blue's favour in the second match when it actually won by a very narrow margin with just 6 games is obviously wrong too.
I think Kasparov was very willing to win both matches, as Kasparov is like that - he would go heart and mind into an affair when his champion's status was being questioned. I am convinced he was well prepared and he actually played better than in many human events. Looking into the games will leave you with the impression of a superb quality indeed (glitches are always there).
I think what is wrong with measuring the performance rating is the use of a single engine that is able to assess better the other engine's moves than the grandmaster's moves.
Rybka sees many good tactical moves that Kasparov does not see and does not see a number of really good positional moves that Kasparov does. You can rely on Rybka, but not anywhere close to even 80% of cases.
I expect that redoing the exercise with Karpov will return even lower performance rating, as Karpov's style is even more positional.
If you use Houdini for doing the measurements, both Kasparov and Karpov's performance ratings could jump, simply because Houdini is a better positional player than Rybka, and it would also be critical of a number of Deep Blue's moves, probably lowering its rating. In this way I think the picture of both matches will look pretty much sensible.
Thanks again for the effort.
Best,
Lyudmil
I have had the thought, that an engine might better prefer the moves of another engine. But it is still just a move, and todays engines are so strong that they find the "correct" evaluation (at least they can beat the best humans). So I don't think it matters much.
I don't think it has to be wrong. My analyzes is done move by move, and look at game 1 - Kasparov made a lot of bad moves here.50 elo difference in performance in Deep Blue's favour when it actually lost the match in 1996 is obviously wrong
You can compare it with a tennis-match where a player wins 3-2 in set (0-6 0-6 6-4 6-4 6-4). If you count the games, the winner lost 18-24. So was he really the best?
The same goes for the second match. Although the match ends with a narrow margin, the difference in performance rating does not need to be narrow. It will probably often be so, but it does not have to.
Perhaps this is the advantage of my analyzes. It may give a better picture of how the players performed than the result itself?!
I would prefer to have this discussed in this thread instead of the most recent posts that adresses the other (usual) things about the matches.
Thanks for your contribution, Luydmil

Here are the result of the two games from the 1989 match.
Surprisingly many errors from both players - I had not expected Kasparov to do so many inaccurate moves...
