Re: Out of the Kai 450 positions, 99 not found by SF

Let divide them to different types (players can be in more than one type and players may be both type 2 and type 3 and type 4 and type 5. <snip> Yes, I get that these are all logical possibilities. What I want to know is what proportion of (e.g. ICCF or any other major CC organization) players of e...

I think I forget that economic conditions and access to high-quality hardware likely vary considerably among ICCF members.
Yes, that's what I was wondering. If they don't own a computer, that makes it hard.

Re: Out of the Kai 450 positions, 99 not found by SF

I'm a 2300+ level player and I have NEVER met an opponent of that level that played a game so badly! NEVER! I'm having trouble believing that that is a "real" ICCF tournament. I've never seen players of that level play so badly! I previously assumed a "bad" CC player would follow an engine too much...

Re: Out of the Kai 450 positions, 99 not found by SF

While about my positional test-suites I had great doubts myself, about positional superiority of Lc0 on a reasonable GPU with a strong net, I have few doubts. Maybe I don't understand what "positional" means. What is obvious, from games, test-suites, is that Lc0 is clearly weaker tactically compare...

If the root binary is LC0, then I would rather use LC0.
Yes, it's been confirmed.
By whom?

Re: What if, SF and Leela were running on same hardware?

SF won the 3rd game with White (but they are now strangely calling that the 1st game). They're running this equal-hardware match "until the GPU is fixed" for CCC10 to resume. SF's win was in the Berlin Defence, which has favored NN engines in the past. I can't see what book moves were used, but the ...
