I will ask him tomorrow, In order to set the skill level you have to subtract how much and set it to what skill level for him, is it 23 or 24 ? Here is Komodo 8 beating Stockfish 14 with a Knight Odds

I don’t know what you ask about subtracting. I estimate skill level as fide rating /115, which is about 21 for Jorge or a bit more. But this formula is largely untested vs humans in Rapid, it could be off a bit.

T 21 Jorge played 2 games and drew one and won 1, probably skill level 22 at TC 15'+10" would give him a challenge, he will try Kill level 22 another day at TC 15'+10"

The hardware doesn’t matter for skill levels except for setting of threads. Formula is for threads = 1, ask Jorge what threads value he used in those two games. If you have dragon 2 you might try 16 or 17 yourself with 1 thread. Skill 16 should be 1840 fide or 1940 USCF in Rapid if my formula is correct.

It would be interesting to see a match between Komodo Dragon and Stockfish with various handicaps, alternating the side playing at a disadvantage.

It would be interesting to see a match between Komodo Dragon and Stockfish with various handicaps, alternating the side playing at a disadvantage.

If the handicap is small (such as c2 pawn, which produces roughly half draws and half Black wins with equal super opponents), it will just magnify the elo difference between the engines, currently favoring latest SF. If the handicap is large, like knight odds, the winning side will win every game (at least 999 out of 1000). I suppose there is some intermediate handicap at which it might be interesting, such as pawn and two moves (f7 off, e4 already played, WTM).

So he can bump either to Skill 22 with his current thread setting or go to Skill 23 with Threads set to 1 (the normal value for the Skill settings). Perhaps I have overrated the Skill levels for humans at 15' + 10", maybe 110 x Skill rather than 115 would be more accurate for estimated FIDE rating. We need more human data. If Jorge can give us enough results to determine what Skill level (with Threads at 1 or at some known value) is a fair match for him at 15' + 10", we'll be glad to give him the next upgrade (which might be a nice one!) free on request.

He played three games yesterday at TC 15'+10" with Skill Level 22; Won 1, and Lost 2 games. He did not changed the default thread and was happy to find a skill level in Komodo that can challenge him.

Can you ask him to look at what that default setting for Threads is? It depends on the GUI. Could be 12, could be just 1, or some other number; it makes a significant difference. Do you know what GUI he uses?

So he can bump either to Skill 22 with his current thread setting or go to Skill 23 with Threads set to 1 (the normal value for the Skill settings). Perhaps I have overrated the Skill levels for humans at 15' + 10", maybe 110 x Skill rather than 115 would be more accurate for estimated FIDE rating. We need more human data. If Jorge can give us enough results to determine what Skill level (with Threads at 1 or at some known value) is a fair match for him at 15' + 10", we'll be glad to give him the next upgrade (which might be a nice one!) free on request.

He played three games yesterday at TC 15'+10" with Skill Level 22; Won 1, and Lost 2 games. He did not changed the default thread and was happy to find a skill level in Komodo that can challenge him.

Can you ask him to look at what that default setting for Threads is? It depends on the GUI. Could be 12, could be just 1, or some other number; it makes a significant difference. Do you know what GUI he uses?

I just called him and he answered that he is using Arena 3.5.1 and set up the Skill to 22, that is all that he did.

He did NOT changed any settings with the threads, he left it with original settings, according to him.

The default setting of threads depends on the GUI used. It was probably 12, but perhaps Jorge can confirm this. If so, he did very well, as Skill 21 with 12 threads is at least Skill 22 on one thread, probably more. So he can bump either to Skill 22 with his current thread setting or go to Skill 23 with Threads set to 1 (the normal value for the Skill settings).

With Arena 3.5.1, if you just download it and install Dragon 2 with no changes (other than skill level setting), it will just use one thread. To confirm this, click on "engines", then "manage", and note the box "common max cpus" which should be checked and set to 1 if it hasn't been modified. This is fine for the Skill level options (this is how they were calibrated), but for knight odds games he might want to use all 12 threads rather than just 1, in which case set that value to 12. So far you report that Jorge, who is 2458 FIDE, has an even score against levels 21 and 22 combined. My formula of 115 x level gives 2415 for Skill 21 and 2530 for Skill 22, so it appears to be pretty accurate based on these five games, maybe 114 x level would fit the data almost perfectly. For reference, Skill 22 generally loses to full strength Dragon with knight odds, while 23 tends to come out ahead.
