CCRL scaling versus human player

I guess this is already a well documented subject but let me ask it my way.

I wonder if some kind (very) good chess player would accept to play some games against middle range engines (2200-2700 CCRL elo rating) at CCRL 40/4 TC in order to rescale CCRL rating to FIDE rating.

Re: Using Linux To Test Engines

I more or less always use linux for developing and testing. Many engines have linux executable, so no need for wine. Just use native linux cutechess and linux engines.

Re: A complete 2000 lines of code engine

In this game versus redqueen, Minic decided to trade down its two rooks for an army of passers and to win the game... And I like that ! :lol: [Event "Computer game"] [Site "https://lichess.org/O23UKywb"] [Date "2019.06.17"] [Round "?"] [White "RedQueen 1.1.3"] [Black "Minic 0.65 64-bit"] [Result "*"...

Re: Weird results Tunguska 1.1 vs Jonny 4.0

I think after some games was discarded, Minic 0.47 4CPU on CCRL 40/4 is only missing 9 games to get an official rating again. Would it be possible for someone to run them again so that this version gets an official rating ?

Many thanks

79 moves is the maximum currently.
I think 128 is plenty for gameplay. For analyzing 256 is bullet proof.
I agree. I really don't know how I've came up with the 512 initially ...

Re: Using evaluation hash score as current bestscore (initial guess)

Here is the idea :
- first write all margins under the form : a*depth+b
- second
* if static score is from eval : use the usual "a"
* if static score is from hash : only use a proper "b" (and a little "a"), make use of (depth-h.depth)
