Re: New Cerebellum Library

I'm hoping for a robot that can update the great NCO or some similar work. In textform. With all the computer analyses and human style comments, pages to flip through. Somebody would make spreadsheets from it I think. I would pay for that even if it was 10 volumes. But it would not make the publishe...

Re: A restrictive pawn sacrifice

Took a look at it with old Kaissa II in Multi PV. In the game, exchange of Rooks on d8 seems not to hurt but after that, White move 23. Nfd2 is probably inaccurate. Kaissa probably can't see an inmobile B though. In the main line with Nbd2 plays g3 and gets B moving at the cost of a castle pawn agai...

Re: Singular extension ... again

Hi Vivien, The more nodes in which your engine can find the best move, also if the differences appear small, the better it will play positionally and that wins games, even for someone who is as strong as Morphy. But alpha beta (maybe even more the case for PVS) is geared very much to playing 'not lo...

Re: Singular extension ... again

I read it a bit like this. If you are close to the horizon, ttValue is correlated more highly with the static evaluation of the position, your best estimate of a precise value now. But as depth goes up and you get back the result of a nullwindow search with a lower bound, the lower bound becomes mor...

Cooking the Cook (not)

Suggested repair is moving the Knight one square down :roll: Now it is become a simple Mate in 10 problem... Won't get a prize. It turned out not to be easy for Kaissa though it had the first move wrong. At least that is what it thinks. So, for engines: who finds the right move fastest and sees Mate...

Re: EG Cook

Do you suppose the study could salvaged, beit with a different solution (or is the idea gone that the author had)?

Re: Really difficult mate

I'm afraid for Kaissa with 1 thread, move 13 was too difficult as well. Too many quiet moves perhaps in null window search. But with a few new modifications at least it found the right move 13 just now on my PC, after letting it simmer overnight. When it gets 13. Nxf4 finally down to -12 it can find...

Re: No chance

No he is not :wink: You'll want to get in touch with Lyudmil Antonov. https://github.com/lantonov/asmFish I think there is a way to contact via asmFish's repository. Maybe he can be reached by just posting on Fishcooking but there is an awful lot of noise there. But maybe he'll read it. https://grou...

Only for CTF and the Forum Help Forum of course. You have to be a member to get in, and once you are a member, they never let you go, even if you want to. It is too dangerous, you know too much.

Re: Did Leela miss a win in the KGA vs SF here?

As a poor player, I would just think with White "Why can't I take that h-pawn? I'm a piece up then" Kaissa thinks, it might be a bit poisonous after all. It takes a while to really see something like +2 though. It reaches 2.19 then it goes down. My guess is it is still a draw. rk6/1pp4Q/p3p3/2b1q3/8...
