Thanks, I wrongly assumed that if it wasn't on the 40/4 list, it wouldn't be on the 40/40. So if I'm right about adding 100 for FIDE comparisons at standard time limit, only the world's top twenty would be favored against it. Of course we didn't specify the processor or opening book, these things matter. Anyway it is about a class weaker than the Arasan 18.0 which I've been using in my handicap matches. Probably this means that Komodo vs CM 9000 both on one thread would be a close match at knight odds at some rapid (not blitz) time control. But it doesn't follow that we could give knight odds at that time control to world number 20 human.

I think that the only way to know is simply by playing.
It may be interesting to have knight odd rating list for chess engines.

It is possible that there are engines that are better in converting a knight advantage to a win and not better in normal chess.

CM is a class weaker than arasan18 in normal chess.
We do not know if it is a class weaker than arasan18 in knight odd games.

In my experience any diffences between how engines play with handicaps or with certain openings etc. are usually fairly small. The higher rated engine always does better, unless they are very close. It is possible that CM has extensive knowledge about how to play when a piece ahead, but extremely unlikely. One exception is that engines have trouble giving weaker or crippled versions of themselves as much handicap as you would expect based on ratings.

I believe that top GMs like Nakamura or MVL can bring back the excitement of Computer Vs Humans.

I might be wrong to assume that Komodo is the program that performs best giving handicap odds, Am I correct, or there is another program like LC0 ?

I ran Stockfish 10 against Arasan 18 at knight odds with same Contempt and time limit as Komodo. Stockfish lost by 14 elo less than Komodo did (57 elo vs 71), with the margin of error on each test a bit over 30. But Stockfish is rated 80 elo above Komodo 13.01 CCRL 40/4 1 cpu and 110 above on CEGT 40/4 1 cpu. So Komodo is much better than Stockfish at giving knight odds compared to its strength in even games, which is logical as it has special code about winning material advantages. As for Lc0, their first series of networks, culminating in 11248, is very good at giving handicaps; it scored about 70% in blitz games giving handicaps averaging around knight odds to GM Naroditsky, an excellent blitz player. However more recent networks are just awful at giving knight odds, they just make blunders. Lc0 just plays awful chess when the winning expectancy gets down below 2% or so. For the old networks that only happens around queen odds, but for the new ones it happens even below knight odds.

I think that the same elo advantage in normal games is not translated to the same elo advantage with knight odds.

The right comparison is of programs with the same playing strength
so you can compare Stockfish10 1 cpu with Komodo 4 cpu that are almost the same strength and see if Komodo does better with knight odds and how much better.

In the year 1993 he was rated 2345, but depending how active he still is, a players over time lose somewhere between 50 to 100 rating points and in 26 years it could be very different than was he used to be. I would say based on that point of view that he might get one or two win versus Komodo with a knight odds, but with a Rook odds Komodo might still get a few draws if he is still around 2250 to 2275 Elo and that also depends on how many cpu you will use with Komodo
