I don't want to comment to explain my ideas to other people.
I don't want this.
As somebody who has tried to do this years ago, my publisher has told me, that the people are not interested in detailed experience. And that the level of the readers reading magazines is not that high.
Therefore I don't explain in public. Maybe you should read Europa Rochade. Their some people have not given up edudication of readers.

I don't know why all the others don't tell us about their experiences in Den Hague. I guess they don't want. And while we are talking here, many of them program much they have learned into their programs.

I have not seen any stuff from Stefan, although Shredder must have made many experiences in Den Haag. Also I have not seen anything from Ferret. Although ....

Also I would have liked to hear from Kallisto guys, from Dragon guys and from other guys.

I guess many do not talk here because they think they cannot profit anything.

I think this is not true. Showing the others the games and the problems could lead to some programming advances and new ideas. But maybe others don't want to share IDEAS ??

Bruce was not able to play one single game against me - oops, sorry , Chess System Tal.

I asked him often and often, but he don't wanted. I don't want to comment on this, because I was disapointed about the fact.

Meanwhile I let chess system tal play against many WEAKER programs then ferret, e.g. Mchess-Aegon97, cilk-chess (one CPU) and others.
Also against Patzer (this program gave CSTal a tough fight... I was totally disapointed watching the mess.) and others.

I have not find the time to make a report about this. And Chris last reactions on my posting do not let me want to work on this.

>I mean we're not talking eskimo, no? :)

Thats my problem with you: I don't understand this comment about eskimo's. It is a sentence that fills a gap, but which gap?
It is a joke ?! Aha.

>And your commentary on bruce. Good one. That was always my point. He's thinking
>the world was invented by him in some ways.

Bruce is -as I registered in Paderborn  (my prejudice was therefore right) a nice guy. He has a nice wife and an unbelievable funny son. He can be proud not only on ferret, he can be proud of whole of his family.
I liked the time and tried to explain his son the difference between Star Trek and Star Wars. But I was not very succesful. I guess Vulcans are not that interesting like Darth Vader or other horro-stories. I have come to the conclusion that Star Wars is more for kids, and Star Trek is more for adults.

From my point of view, I joint the time with bruce and co. and my only problem was, that I sometimes thought that my good feelings were not echoed, what has made me a little disapointed, but it is not the place to discuss emotinal things like this here....

>And he did agitate me a lot with
>his superficial remarks about concentration camps.

I don't know what you wanted to hint on with this statement.
I hope it is not meant against Bruce in any bad connotation.
This is the problem I have with you. Sometimes I cannot see if you want to attack somebody or not.

I try more to make it obvious what I think about a topic.

>But we'll see if he could

Maybe Ferret/Bruce has learned, that all the many games played on the server are also very often GAMES FOR FUN. And suddenly he saw games played by people, also in a relaxed atmosphere, but played not to waste some time playing chess, but played with the target really to win.

This is IMO a big difference. I don't want to know how many games on these servers were played for fun, but were count in a statistic with all the other serious games played there.

>If you think the writing about computer chess prgs coud be boring out of
>topic, please send me some material via email. Thanks.

Ok, this might be better possible, not for the public. I get nothing back when I am talking or reporting. When I discuss here, I get something back. Therefore I prefer not to speak in monologues, but in dialogues.

>Did you oversee that I was with Bob the only one to analyse and comment on this
>famous CSTal sac on f2? Ah, I forgot bruce again!

They have tried the move on their programs. Their programs did not play Nxf2. Therefore in their universe they say:
The move must be incorrect. If MY program is not finding it, it must be incorrect.

I think this is a little shallow. also I don't think that it is easy to analyse about this move.
Whatever it was, CSTAL has not played the move because it has seen anything. It is designed to play these moves without seeing if it works.

BTW: My friend Peter Schreiner has written an excellent summary about Chess System Tal in Europa-Rochade, and he has used the Nxf2 game as an example together with another game.

But - I guess - less people will recognize the move.... or ?

This was the 15' blitz game we played against Mchess-Aegon97 , both programs having the fast Hewlett Packard P6/200 Mhz tournament machines.

We stopped the game here, because peter was so much involved in talking with a lady from Focus or Spiegel about Mchess, that he was unable to concentrate anymore on real computerchess.
The lady searched for Frederic Friedel. She said, can you tell us where I can find Mr. Friedel. Ha - we both laughed , than she is right here, we said (and grinned in mind!). Why do you looking for him ? Ah - she said: I had to write about an intelligent chess program, Fritz or something like that.

Fritz ?! We or he (I don't have it in mind accurate Peter... ) said: but if you want to write about an intelligent program, you have to write about Mchess, of course....

Fritz ?! We involved the lady in some minor discussions about Friedel and his clan and we were all very amused, the mood was good and much insider jokes flew though the air....

Also one day we played on the hotel room, and a very very nice game happened that made me sweat very much. It was against XXXX2 , Martin Zentners program.
I thought it could be a good idea to get a revange for Paderborn 1995, where chris' program played c7-c8N and lost the game although the position was a mate against XXXX if CSTal would have played the promotion into a queen. It didn't .
In the revange game, CSTAl sacced something and XXXX2 defended like a tiger. But moves later it overstressed the position and lost the game.
What a pity that I have not saved this game. Maybe somebody has deleted it from my harddisc in a moment I was not there... maybe martin has saved the game, whatever- it was a pretty cool game and the revange for paderborn 1995 was a win for cstal.

Oh - no - here it is, I found the game....

Look yourself the unbelievable game:
I don't know the time control, but XXXX2 got Peters P5/200 and I used my P5/120 for Chess System Tal ...

Wasn't this an unbelievable game ???

We discussed much in Den Haag.  I met Don Daily, who is a nice guy working on the CILK-CHESS project. I guess this program has more chances ever to win against Kasparov than any other program.

Don Daily likes to implement chess-knowledge into his parallel-program. Although he had only a small notebook with him, we played some games, I wanted to know about cilk-chess - of course - and the best way to find out about a program is to watch the games, and watch the evaluations and main-lines.

As you now see Rolf, CSTal is almost always good for a spectacular sac or a promising undercover-job.

We will never see games where no side of the players have an idea, this is the step into funny games....
