I am working on a new release when I can and that is not very much or very often these days. So the last public release at the WBEC site is the one that I will send.
Sent. Let me know if Romi did not arrive.

Also on Jim Ablett's site, pgo compiled 32bit and 64bit versions are available.

In CCRL Romip3k is 2508, CSTal would be 2505.
And Tony's list has 2642 for Romi, So CSTal would be around 2638.
Since RomiChess has among the thinest of evals and CST has among the thickest and their ratings are so close and their styles so unique it would make for one very interesting match. I suggest a CCRL style match!

CST might prevail though as Romi has no king safty code or endgame knowledge or internal draw recognition and a whole bunch of other eval stuff.

Anyone else interested in such a match? Anyone have any results/games already to share? DWD? :D
Hi Michael,
All I have for now is this in my rating list at long time controls:

Chess System Tal II 2364_188 games played

RomiChess OW2c 2321_188 games played
RomiChess P3j i 2261_188 games played


_Reference engine Fruit 2.2.1 2720


RomiChess P3k is in my waiting list,waiting of course :mrgreen:

Chris:
If you feel it is no proper to do what I said I could do, just tell me and I will not do it.
Or perhaps the receiver of the copied stuff could deliver to you the book you choose? That would be another way...
I do not pretend to get a profit of this. I have given many things for not even the cheap book as a compliment, but simply these days I cannot do it anymore due to financial problems. A $5 book just cover PART of my post expenses, the package, etc. In terms of my motivations, you know well I have been a fan of Cstal since lot of time, even writing some stuff about it as you surely remember. So when I offer to do this, with the investment of time of copying a disk, going to the stationary to get an envelope, then to the post office, etc, I do it to keep the flame .
But, again, if you feel different, just let me know.
Truly yours
Your friend Fernando.

Hi Fernando,

No problem for me - this stuff is not in any way my property any more. Not really very sure who owns it now, maybe the liquidator - for sure somebody owns it, ownership doesn't just vaporise into thin air.

I do know there are some very sore venture capitalists out there who lost around £16mn of investment, and they might just love the opportunity to sue someone (via the liquidator) to recoup some few shekels.

Beware of sharks is my advice.

Your old friend,

Chris

do you mean the one I wrote that has never been published?
Very interesting that you rewrote CSTAL with bitboards. I remember reading the very interesting debates you had with Bob Hyatt over the usefulness of bitboards in eval. How do you approach the eval with bitboards? Do you still use attack tables? I would be very interested in a version to play against...

Hi Chris,

Didn't Jeff Rollason over at AI Factory (www.aifactory.co.uk) buy the source code and rights to CS Tal and all of the old Oxford Software apps? They certainly sell a chess program called CS Tal on their website.

Cheers,

Steve Maughan

Hi Chris,

Did you sign a non-competition agreement? If so, when does it expire?

If you are not (now) under an agreement to not write another chess program then what is stopping you from writing one? 8-)

Oh, let them try....First they should know. Then they should come here. Then, to probe I did sent the stuff over there. Etc.
Sore maybe they are, but I doubt they are so dumb people to try that gamble.
In any case no one took my offer, so the shop is closed.

To anyone of the badly harmed guys regards
Fernando
