Match Rebel 8 - Chess Wizard on PP200
Frederic LOUGUET
Here is a PGN file of a match I recently did between Rebel 8 and my own
program, Chess Wizard (which won the last French Computer Chess
Championship with Chess Guru). Time control : 30 minutes, sudden death.
The result : Rebel 8 won +6 = 1 -5 which I consider of course a very good
result, even if there are only 12 games. The programs were running on two
Pentium Pro 200 PCs (60 MB hash for Rebel, 20 Mo for Wizard).
Chess Wizard is a highly selective program, with a lot of knowledge in
the eval function. It uses the bitmap approach, like Crafty and Chess
Guru. However,it is very speculative in its evaluation (reminds me of
some other program...) and has a lot of special algorithms regarding
space control.
It is quite slow compared to a lot of other programs (6000-10000 n/s on
Pentium Pro 200), but I think it is not too "stupid" (that is, for a
chess program :) Chess Wizard is two years old now, but the French
Championship was his first official tournament. It is possible I will
enter him in the Aubervilliers Grand Open, on January 26, 1997 (which I
think is still the biggest open in Europe for active Chess).
To answer some questions I see coming :
- I will NOT sell Chess Wizard. There are already a lot of strong
programs with nice interfaces on the market (too much, in my opinion), so
I do not intend to make any money with it. My program has only a
text-based interface for the moment (and maybe for a long time...). And
also, I believe that commercial programmers who earn a living by making
chess programs should be able to keep on just doing that. I fear that in
a year or two, there will be so many chess programs that the market could
possibly die from it.
- I will NOT make Chess Wizard available to the public, not in shareware,
not in freeware, or anything else. This is a personal project, it always
was and will always be, until I see that I can't progress anymore, or it
is clearly the best program in the world :) One can always dream...
- All I am interested for now is to make it stronger and stronger. I will
not cook books against other programs, in fact I consider it is a
complete waste of time for a non-commercial program, which is not driven
by sales figures.
- My goal is to make Wizard play well by itself, in any kind of position.
So I will not make it avoid closed positions just because it is a
program. To be one of the best in any category, you must not hide
weaknesses, you must fight them. If it loses in closed positions, it's
fine with me for now. I have plenty of time to improve things.
- I will not send Wizard to the SSDF. I do not care about SSDF ratings.
Period. I do not say they are useless, but I prefer a bit more mystery.
Playing strength cannot be reduced to a figure in the SSDF list.
- Now on the technical side. Wizard uses different extensions at
different time controls, and his eval parameters change also with the
time control (more agressive in sudden death). It uses an alpha beta, and
heavily prune forward by evaluating the position at each node in the
tree. I use the Visual C/C++ from Microsoft.
Wizard plays already better than in the French Event (bugs
found, better tactical strength). I have put about 50% of the knowledge I
want to put in it. And, I am not in a hurry... I have no deadline, no
pressure. As I do not work full time on it, it will take a long time to
make it play the level I want it to play, but this not a problem. I hope
it will progress slowly, but relentlessly :)
Now, I have a question on a topic which I think has not been addressed in
this newsgroup for a long time : recaptures extensions. Since Wizard
plays reasonably well positionnally, I will concentrate on its tactical
abilities for a few months. I was wondering what recapture extensions is
considered to be optimal by other programmers. This problem is not simple
at all. I am considering for now recapture extensions of equal material
on the same square, plus quality sacs, plus exchanges around either king.
I do not use fractional depth extensions, since I have not seen great
benefits from them. Maybe I am wrong, I don't know for sure.
Any comment regarding the games against Rebel will of course be
appreciated. There is no doubt that in some games Rebel crunches Wizard,
but I was pleased it happens also the other way sometimes :) Next match :
Genius 5 !

This is an interesting economic concept. I always believed that
competition resulted in product and service improvements in a free market.
The computer software industry operates in essentially a free market.
There are no obstructions to entry, producer or consumer power advantages,
disadvantageous regulations, etc.
How would entry of more computer software programs on the market hurt the
industry? By driving out noncompetitive companies? Why should they
persist?
If this is inappropriate for the list, please respond by e-mail. Thanks.

If the market is a big market, then a lot of competitition is obviously a good
thing. If it is small, as it is the case with chess programs, and the new
competition is good, the market share of each company involved decreases. The
chess programs market is not a spectacularly expanding market. More, only the
strong player and passionate lovers of chess computers are really interested in
the strongest programs. Many people do only know about Chessmaster 5000,
because it is sold by a big company. I think we could be soon in a "too many
predators, not enough preys" market. When there is nothing to eat, well :) Of
course, it is only a personal opinion, and I fully respect other opinions.
It would be interesting to know about commercial programmers opinions. If they
all feel their income will steadily grow in the next few years, I am probably
wrong.

I think you are right on. It's the competition that results in
improvements to programs, hardware, et. al. I find the differing
attitudes of Crafty's programmer and that of Chess Wizard quite
amazing. Crafty wants to share everything, have the program run on all
platforms, seek advive from other programmers, etc. Wizard does not
want anyone to have or use his program whether he makes money or not,
but of course he wants to tell us how good his program is. I wonder
why???

It could be any of a number of things. He might be intimidated by the
note I posted where I have personally responded to nearly 1,700 email
messages since June of 1996, which is a daunting task. :)
I don't see a thing wrong with someone wanting to keep their code
private. 25 years ago I was the same way. Now I'm old enough to
hope that one day someone will take Crafty and run with it, when the
day comes that I can't keep up any more. :) When I was 20, I thought
I'd always be able to keep up. Amazing what a little time does to you.

Ok. I see that polemics happen quickly in this newsgroup. I am not this kind of
guy. I simply showed the games because I thought somebody could be interested
in replaying them. After all, one is supposed to enjoy himself by playing
Chess, no ? So, I understand that some people would be pleased to get EVERY
chess program in the world, and would be even more pleased to have every
programmer give their program to anyone. Fine. It is perfectly understandable.
I think the Crafty experience is quite interesting, and I already exchanged
some ideas with Bob Hyatt in the past (about outposted knight which can't be
attacked by other knights or bishop on the same color, for example...). So, I
am not unwilling to discuss things. However, I am unwilling to give away my
program. It's my right, you have to respect it as I respect your opinions. And
there are a lot of programs which are not avaiable to the public. I am not the
only one, and will not be the last. Besides, I never claimed that my program is
better than others, so I think you already have better choices...
And if I choose to have testers for my program, they certainly will be tolerant
people. Now, if the simple fact of publishing games for information is
immediately answered by this kind of post, I don't think I will spend a lot of
time here. Thanks for the feedback.

Frederic,
I fully support your decision not to release your program. Please do not
misunderstand me. Of course it is your right to do what ever you wish with
your intellectual property. I was merely wondering about your _economic_
philosophy! Please don't let this little matter keep you away from the

Frederic,
I completely sympathize with you. I too would be proud of my efforts in developing a
program and as such would want others to migrate in its progression. First thing I
did was dl the games. I looked at one really quick and will at the other ones in the
future. Please don't be curtailed by someone who thinks you have some malignant
evil tumor hidden underneath your innocent posting.We welcome your presence here and
look forward to Chess Wizards growth.

This is a useless discussion, because no matter what side is right
there is nothing you can do about it. Economics is supply and demand.
Nothing more and nothing less. Every industry is subject to it.

This looked unnecesary. I doubt if any human would ever consider
this, especially since the Knight shows it's superiority in endgames
vs a bishop with pawns on the same side of the board. And here
two extra pawns at that. These programs are so strong now yet
it is still amusing when the make these type of moves. There are many
examples of a bishop and king drawing against three or more pawns
in Yuri Averbakh's "Bishop Endings". Here's a bizarre position by
S. Lloyd on page 18.
White:Kc3 Bh3
Black: Ka4 a5 a7 c7 d6 e5 f4 g3 h2

Another observation was the big plus score for the black
pieces.
Have you autoplayed any
40/2 games? If so I would replay these also.
Thanks for posting these games.

Unfortunately, auto232 does not work under Windows, so these games were
manually manipulated. I have not yet played 40/2 games for this reason. I am at
this moment playing 15mn/KO games with Genius 3, which is one of the very best
at this time control. We'll see...
I agree that Nxg7 was quite strange. If Rebel had kept the knight of course it
would have been very bad for Wizard :)
I would like to thank you, as well as Lonnie Cook, Bob Hyatt and Ingo Althoefer
who sent me a mail, for the support and constructive analysis. There are indeed
tolerant people in this newsgroup.

No no no.
If everybody ran away because of some negative stuff, there'ld be
no news group.
This is a free forum. That means both fools and clevers reply.
