Chess.com is only interested in providing live commentary for matches with "big names", which cost real money (we do give small prizes for wins and draws (triple for wins) in all matches). Hopefully we'll have such a match before too long. Saturday's match can be regarded as preparation for such matches, in terms of determining fair time limits for knight odds, finding flaws in play at knight odds or in the online play, etc. We've already pretty much proven that we can give two pawns (as White) or f7 and two moves or knight for f7 pawn or the equivalents to strong GMs in rapid play, but in the opening a knight is worth nearly four pawns so we need to establish that giving knight odds to a GM is not ridiculous, so an IM is the obvious step. If knight odds proves unreasonable for GMs, there is still f7 and three moves as an in-between step, which we tried twice at slow rapid, losing to GM Simon Williams but beating IM Danny Rensch. But beating a GM in a knight odds match is the "holy grail" of chess, the ultimate challenge.
What timing are you hoping to beat a GM at knight odds ?
I don't know if "what timing" means "when" or "what time limit", but since we can already do it in blitz while it is not a realistic goal for classical time limits, we are talking about "rapid", and since the FIDE Rapid Championship is at 15' + 10", I think that is the appropriate time limit for this challenge. GM also needs to be narrowed down; I'm a GM but no longer play at GM level, so I think it should be a GM with a current FIDE rating (including recent games) over 2500, the normally required rating to get the title (except for winners of World Championships in their categories). With these conditions specified, I hope we can do it sometime this year, although it might not be a wise bet to make.
By the way Komodo has now played more handicap matches with titled players than I can count or remember, but I'm pretty sure that only one player has a plus score against Komodo in these matches. That would be the very first one to play Komodo a match, namely FM Victor Bolzoni, FIDE 2189 at the time (year 2015), who beat Komodo 4.5 to 1.5 at knight odds at 45' + 15", which is on the cusp between Rapid and Classical chess. So our performance rating then was a bit under 2000 FIDE, and with later knight odds matches it dropped further, whereas the average performance for this year in 17 knight odds games is about 2350 FIDE, although the average time limit was somewhat faster this year. So maybe close to 300 elo improvement in knight odds play in four years, a lot more than the improvement on the rating lists. Probably it's because MCTS is harder for humans to play against than A/B, also Contempt helps a lot.

I know Christophe Sochacki, 2521 in rapid, ( http://ratings.fide.com/id.phtml?event=662569 ) from France, he plays for my chess club in Belgium.
In 2019, he won a rapid tournament just ahead of GM EDOUARD Romain (2655) and GM LAGARDE Maxime (2661) : http://www.echecs.asso.fr/Resultats.asp ... &Action=Ga
IIRC, he has 3 norms of GM so he only needs to reach 2500 Elo to get the GM title.
I showed me a couple of his games and I am impressed.
If you want I contact him, tell me.
But I expect a clear win for Christophe (3-1 or 3.5-0.5).

Sure, we'd be glad to play him a knight odds match, but I don't think chess.com will want to broadcast or sponsor a match with an IM so we can only offer small prizes per win and draw as there is no real publicity value, it's just to see what we need to improve and where we stand. I think you are right, he should win the match, I would estimate we're around 2400 Rapid FIDE at knight odds at 15' + 10". Let me know if he is interested and if so we'll talk further.

Maybe you just wait until he becomes GM, if he's that close.

Well, he is 2470 FIDE so "close", but he reached 2459 six years ago so it could be years before he reaches 2500, or it could happen quickly.

It's still hard to believe for me that you can lose a rapid game starting N up if you just play classical openings and keep the centre. I mean playing the Sicilian or Bogo-like opening allowing white to take space can't be an optimal strategy in those.
I would love to try it myself. What kind of hardware is used in those matches? Do you think it matters much?

Have you tried it? Are you able to beat Komodo with high Contempt starting a N up?

I only tried SF and I beat it without problems although I took some practice to get to that point. What are the optimal settings for Komodo? Is it better to use standard one or MCTS? I will renew my subscription to try it.

Tried one against SF:

[pgn]
[FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/R1BQKBNR w KQkq - 0 1"]

1.Nf3 d5 2.d4 Nf6 3.c3 e6 4.Bf4 Bd6 5.e3 O-O 6.Be2 c5 7.dxc5 Bxc5 8.O-O Nc6 9.Rc1 Bd6 10.Bxd6 Qxd6 11.c4 Rd8 12.Qc2 dxc4 13.Rfd1 Qe7 14.Rxd8+ Qxd8 15.Bxc4 Bd7 16.a3 Qe7 17.Bf1 h6 18.Qb3 Be8 19.Be2 Rd8 20.Qc2 e5 21.Nd2 Bd7 22.b4 a6 23.h3 Rc8 24.Ne4 Nxe4 25.Qxe4 Nd8 26.Rxc8 Bxc8 27.b5 axb5 28.Bxb5 Qxa3 29.Qxe5 Be6 30.Qb8 Qe7 31.Kh1 g6 32.Bf1 Kg7 33.Qa8 Bd5 34.Qa5 Bc6 35.Qb6 Ne6 36.Kg1 Qc5 37.Qxc5 Nxc5 38.f3 Kf6 39.Kf2 g5 40.Ke1 Ke5 41.Kd2 f5 42.Kc3 Ne6 43.Bc4 f4 44.e4 Nd4 45.Bf1 Bb5 46.Bd3 Bxd3 47.Kxd3 b5 48.Kd2 Nc6 49.Kc3 b4+ 50.Kd3 Na5 51.Ke2 Kd4 52.e5 Kxe5 53.Kd3 Kd5 54.Kd2 Kd4 55.Kc2 Ke3 56.Kb1 Kf2 57.Kb2 Kxg2 58.Kc2 Kxf3 59.Kd3 h5 60.Kd4 g4 61.hxg4 hxg4 62.Ke5 b3 63.Kd4 b2 64.Kc5 b1=Q 65.Kd6 g3 66.Kc5 g2 67.Kd6 g1=Q 68.Ke7 Qe4+ 69.Kf8 Qc5+ 70.Kg7 Qee7+ 71.Kh8 Qc8# 0-1

[/pgn]

It's always similar story. I think one should stick to the following:
-play as classical openings as possible, put pawns in the center (e4 e5, d4 d5 etc.)
-don't fianchetto anything
-don't gambit anything (I didn't play 3...c5 cause I wasn't sure white can't defend the pawn without Nb1)

I would love to see an engine that can win against me when I do that :)

The hardware is a 16 core i9 at 4.1 GHz, plus a 2080 ti for the nn. Of course you can't try the nn yourself, it's not yet public, but you can try Komodo 13.25 MCTS which doesn't use nn or GPU. If you have a pretty fast 8 core i7 that shouldn't be too much weaker than the i9. Be sure to set Contempt to 150. Another thing you can't duplicate is that we use a small opening book, itself derived from Komodo MCTS nn analysis, to provide sufficient variety so you can't learn exact sequences to repeat. Assuming you have a good i7, the combined effect of the hardware difference plus the nn contribution plus the small book is probably something like 150 elo or so.
What are your various OTB ratings, FIDE standard/rapid, national, online blitz or rapid ratings? Your results won't tell us anything if we don't know your OTB level. I recall you are a strong corr. player but that is not highly correlated with chess skill anymore, now that engine use is allowed. If you have reasonably high ratings that I can verify with your real name, we could play some games at knight odds on chess.com.
