Re: Why there is no interest in Computer with odds Vs Humans match?

There should be more computer with 2 pawns or Knight vs pawn odds that will bring back the challenge of Humans GMs vs top Engines. :shock: I believe that top GMs like Nakamura or MVL can bring back the excitement of Computer Vs Humans. I support your quest. I'd find it even more interesting in time...

Its not about the root position, its about the positions that get explored.

Somewhere in Ethereal's search, the given position is reduced to a 5 man one, via a serious of (potentially awful) exchanges. This is when criteria #2 is met, and TB hits are occurring.

Re: Test Position

Actually I couldn't care less for CB abnormalities. I can assure you that Laser itself has no clue about the path (should be clear of course), so you have to find the problem in your CB usage. Why don't you just create a Laser entity with explicitely no path under a new name, if you cannot solve yo...

Re: Test Position

It is no problem with Laser. The default option is 'empty' for the Syzygy path. Probably you have several CB programs installed and it gets the path from one of those, or you had it saved with your Laser config in the CB program you use. (e.g. in : C:\Users\XXX\AppData\Roaming\ChessBase\Engines.UCI...

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

But to me the only reason for a test- suite to get outdated was, if it was solved too easily and too completely by new arising engines. No reason to update because a single one new engine doesn't perform good enough for some fans of the new engine. That's pretty unreasonable to Dann & Swami conside...
