Bad Gyal 4a

The endgame data was problematic. This is a rerun without that data at 128x10. This should be the strongest net tactically, including T40, LD2.

+2

Re: Any engines solve this one?

Hi Eelco Yes, but does not mean that CyberNezh has a wrong PV, if it recognizes somehow that Qh4 also does not cut it. White's clearly winning after 1.Nd4 Qh5 2.g4, with 2...Qh4 as well as with 2...Qxg4. 2...Qh4 3.Nf3 and 3...Qxg4 is refuted by 4.Rhg1. After some Forward- Backward of this line and 2...

Most engines in 3MV- mode have Nd4 at third best from very start, yet none with default parameters found 2.g4 after 1...Qh5 within 15 minutes at my trials at 24 threads of ...

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

What happened here? Two things happened: Draw death of engine- chesss and black box- death of intelligibilty of engine- chess. Like Chrilly Donninger used to say, it's like watching the washer washing the laundry. SF et al already were rather unintelligible in their ways of playing, NNs are fully. ...

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

Maybe odds matches in Fischer Random is harder for the human side. Humans are used to the standard opening setup. The unfamiliarity of Chess960 may give the engine the upper hand? Of course, Jon. I still think the easiest to organize and finance was the corr.- thing with the bookless LC0- engine on...

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.
Now I got it, thanks again.

Re: Test Position

Thanks a lot for the new version, Andrew! So SyzygyProbeDepth applies to the highest cardinality for the Tablebases. IE, if you have a 6 man table base setup, If Ethereal probes, then one of the following is true: 1) The current depth is greater than or equal to SyzygyProbeDepth (Setting 127 makes t...

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...
