This program Snowy is a fair match for me, I really had a hard time surviving the opening since I was stuck trying to get out alive, Snowy prevented me from castling but I managed to get out of all snowy attacks and got a drawlkaufman wrote: ↑Mon Sep 20, 2021 6:25 amI imagine he read that the Skill levels were calibrated based on one thread and wrongly assumed that threads were just set to 1 automatically.Chessqueen wrote: ↑Mon Sep 20, 2021 4:41 amSo why cc2150dx Jason Coombs stated this?lkaufman wrote: ↑Mon Sep 20, 2021 3:02 amI think that you played rather well in these two games for a 1950 player at 15' + 10", but you are probably right that the formula is a bit too generous in rating Dragon around levels 16 thru 19. You already know that your friend Jorge Hasbun was even with levels 21 and 22 combined at that level, so the formula seems about right at those levels, and probably Ruiz at 2286 would be somewhere between levels 20 and 21 at that time control. For knight odds instead perhaps try the b1 knight for variety this time, with depth 22 and four threads.Chessqueen wrote: ↑Sat Sep 18, 2021 2:52 amChessqueen wrote: ↑Sat Sep 18, 2021 2:02 am This time I set up the Skill Level to 18 in Dragon2, there must be something wrong with the Skill Level 114 x 18 = 2052 ? Another question is when I set the skill level to 18 is that with 1 core or with 4 cores on my intel i7 3.40GHz ? So far I have been playing those two game with only 1 core
I just Called Adan Manuel Mazara Ruiz rated 2286 and agree to play Knight Odds at 45'+ 10" instead of using Skill Level 18 tomorrow. https://ratings.fide.com/profile/6400248

Skill levels 1-24 are set to play with 1 core/thread regardless of how many cores/threads you set.
I'm really having a tough time deciding what CCRL Rapid rating corresponds to a FIDE human rating of let's say 2000, assuming both players are playing 15' + 10" rapid on the reference i7 hardware. Some people seem to think that the CCRL ratings are way too low, several hundred below 2000 in this example, while others think they are just slightly low in this range. What is your own experience as to which engine or engines are a fair match for you in 15' + 10" rapid?
