Regan's conundrum

Long article, but it shows an interesting question

https://rjlipton.wordpress.com/2016/12/ ... y-grinder/

Larry and Kai (among others) would be interested, I would think.

Re: IPON-RRRL - CCRL'd

If reference engine is sufficiently weaker than top engines -- Rybka 4.1 on a single core, say -- a top engine can estimate it's IPR using Regan's method. This IPR can be harmonized to human FIDE ratings quite easily, through analysis of human games with the same top engine. Then all ratings lists c...

Re: What to play against 1. d4 ?

...e6 allows transposition to the French where white is slightly better than in any 1. d4 line (according to Cerebellum).

Re: What to play against 1. d4 ?

According to Cerebellum the best for black against Nc3 is the Nimzo. Against Nf3 it tells us to play d5 and transpose to a semi-Slav. If white plays cxd5 with his knight on f3 instead of c3, he gets an inferior version of the exchange variation that's dead equal. The Cerebellum demo doesn't tell us ...

Amazing. How can someone leave the field for years and come back with this kind of performance straight away?

Re: Cerebellum says: play the French and semi-Slav

I can't find the post where Zipproth gave the $2000 of electricity figure. It's possible that number was for Cerebellum light. I did find this post where he states Cerebellum (I think the full version) represents 2 years of time on 2 quad-core machines. To do it in a day we need ~ 1500 c4.xlarge ins...

Re: Cerebellum says: play the French and semi-Slav

The problem I see is that it will probably be in the format of Lomonosov, so you won't be able to actually download the full library but instead through their GUI probe the positions and probably couple it with your favourite engine and also add your own positions stored locally. Ofc downloading th...

Re: Cerebellum says: play the French and semi-Slav

Values displayed by engines reflect the opinion of developers only. Their opinion is based on practical games without theoretical evidence. This strikes me as a very strange claim. Engine evals are associated with winning probabilities (through logistic curve). We see that in game statistics and Mo...
