We are reaching the Max Odds that a top engine can give the top 3 GM's

[Chessqueen]

I do NOT know exactly what is the minimum rating for an engine to beat either Stockfish13 NNUE or Komodo Dragon2 MCTS with a Knight odds, but it could be in the range of 2300 CCRL to 2400, anyway I tried Dragon 4.6 rated 2417 and it beat Stockfish easily probably other people will test engine lower than 2417 with Komodo Dragon 2 MCTS comtempt =150

When you post an engine game, you should always include the time limit at least, that's vital info. I'm guessing 15' + 10", but just a guess. I suppose it is single thread, but this is also important to state.
Since you have so many of the near or under 2000 ccrl engines and post games with them, perhaps you can tell what engine, if any, you are able to score about evenly against yourself in blitz, say 3' + 2"? I think you estimated your rating to be in the 1900 to 2000 range, so I'm guess it would be an engine a few hundred elo below that, but "a few" is not a number. Anyone else with a known blitz rating (server or FIDE) who can name an engine which they are evenly matched with, no matter how weak, please post here (and specify hardware and threads). Or it can be a Skill level on a strong engine.

I am tire today I just came from work and after that got an hour training with my Chess trainer online, I will try another day against an engine close to 1800 since CCRL rating is equal to 150 to 200 stronger than human. I strongly recommend you to try against Dragon 4.6 rated around 2417 by CCR, or Zahak rated 2415. Or Komodo Dragon 2 MCTS contempt = 150 against these two with a Knight odds.

256‑257 Dragon 4.6 2417 +8 −8 48.5% +11.0 24.6% 7652
47.4%
256‑257 Snitch 1.6.2 32-bit 2417 +10 −10 46.5% +27.8 25.0% 3997
56.6%
258 Zahak 3.0 64-bit 2415 +26 −26 66.6% −126.1 21.3% 559
54.7%

I don't have Komodo installed, but I'll be very interested to see how does Zahak perform against Komodo in a long timecontrol 15"+2' with Knight odds.

You can download Zahak here: https://github.com/amanjpro/zahak/releases/tag/3.0

OK, I ran 44 knight odds games (b1 and g1, ChrisW book, middle of the file) between KomodoDragon2 and Zahak3 (64 bit) on my I9 laptop, very fast machine which favors the program getting the handicap compared to slower hardware. It was quite a close match. Dragon won by 21 wins to 17 losses with four draws. I would say that this is a very good result for Zahak, because in previous testing, at the just marginally faster time limit of 10' + 5", Dragon performed close to 2600 on the CCRL rapid scale giving knight odds this way. I didn't see a Rapid rating for Zahak (that's probably why I missed the rating before, I must have looked at Rapid rather than Blitz); perhaps it gets better with more time?

Okay I am very slow so I gave myself plenty of time, since I am not use to play Blitz against anybody and my online trainer does NOT recommend me to play Blitz, since according to him it is a rush of who blunder first and of course the engine will NOT blunder in faster Blitz time, so here it is.

I believe that with time control of at least 45'+1" I should be able to squeeze a win against this engine rated 1977, but at lower Blitz TC like less than 15 minutes I would be blundering moves since I am not use to play Blitz and it is NOT good for my planning process according to my trainer.

[Chessqueen]

Mr. Uri Blass, I studied some of your games, you should be able to beat Snowy engine rated 1977 or at least Draw, in Blitz 5'+1"
https://ratings.fide.com/view_games.pht ... ri(ISR)%22

[Uri Blass]

Thanks but the games you give are at time control 90+30 and not 5'+1''

I did not try to play against Showy engine but I guess 1977 elo for chess engine is not 1977 elo at blitz but clearly higher than it and I am not at that level.

Dragon resigns. Congratulations! According to Dragon, Black only made two significantly non-optimal moves in the whole game, neither of which put the win in jeopardy. Did you actually average under a minute per move (it's okay if you took longer, it wasn't a rule, just your estimate)? That's a very high level of play for just one minute per move. Anyway if you still want to play the game with g1 off, I'm willing.[/pgn]

Okay, we can play mirror Alekhine. I need a couple of days to recover, that was quite the stressy session.

When did we begin? Ten days ago? Fifty moves, five a day, so, in theory that’s two hours of awake time per move. In practice moves were in surges, where I’ld worked out where the game was going, then there’s 18 hours or so. Obviously I’m not thinking position all that time, but I can chew over general principles, in this case: defense principles. I liked Ne5, Qe8, light squares. I think e6 was a mistake. Pawn could perfectly well have stayed on e7, and I basically had a tactical defense of g6, namely the f-file.
After that I figured as long as Q stayed connected to Bg7, I ought to be able to maneuver around the strong center with the nuisance knights and you’ld just run out of possibilities. Er, wrong.
Nf3+ was a shot at being okay by getting rid of your Bb2, but again wrong, and against defensive principles, I got careless and started mixing it tactically, which is absolutely dumb thing to do. However, again I figured B back to g7 and all would be defendable again. But.
Well, but. Fortunately, by temptation or not, and possibly just running out of possibilities, you went for the Bg6+ line and Q vs RBN-center pawns which I was very confident would be a win.
On reflection, especially after e6, much of the game was quite predictable and much of it was forced. White had to press. Black had to try and make fortresses where everything defends everything and nothing is hanging and human doesn’t have to keeping thinking tactical. Then we come down to space and mobility (white had in spades) against one more defensive piece (and a center). QRBB is a very formidable combination of pieces of course. Curious how e6 played such a key part for both sides, then finally becoming the decisive pawn.

So, yes, mirror Alekhine, couple of days break.

Congratulations again for beating such strong Engine Komodo Dragon2 MCTS with Knight Odds. probably very soon we should see the beginning of another great chess game. What would be the starting 3 moves for the mirror Alekhine opening ? I believe that this time you should take the White pieces and let Komodo Dragon2 MCTS chose whatever Opening it select for Black instead of the mirror Alekhine forcing White to play with 1. e4 ?

A more interesting experiment would be for Komodo Dragon2 MCTS to give you a Knight odds, but the White pawn on the first move can NOT move beyond the third rank, so either 1. e3 or 1. d3 or you cab chose to move either of your Knight

I think you are confused. "Mirror" Alekhine doesn't mean switching colors, that would be ridiculous to increase the handicap. It means switching which White knight is removed. So g1 instead of b1 removed. By the way, with b1 knight removed, the best opening move for White is probably 1.Nf3, so not allowing 1.e4 and 1.d4 does not increase the handicap. With g1 off, it would.

After that I figured as long as Q stayed connected to Bg7, I ought to be able to maneuver around the strong center with the nuisance knights and you’ld just run out of possibilities. Er, wrong.
Nf3+ was a shot at being okay by getting rid of your Bb2, but again wrong, and against defensive principles, I got careless and started mixing it tactically, which is absolutely dumb thing to do. However, again I figured B back to g7 and all would be defendable again. But.
Well, but. Fortunately, by temptation or not, and possibly just running out of possibilities, you went for the Bg6+ line and Q vs RBN-center pawns which I was very confident would be a win.
On reflection, especially after e6, much of the game was quite predictable and much of it was forced. White had to press. Black had to try and make fortresses where everything defends everything and nothing is hanging and human doesn’t have to keeping thinking tactical. Then we come down to space and mobility (white had in spades) against one more defensive piece (and a center). QRBB is a very formidable combination of pieces of course. Curious how e6 played such a key part for both sides, then finally becoming the decisive pawn.

So, yes, mirror Alekhine, couple of days break.

Congratulations again for beating such strong Engine Komodo Dragon2 MCTS with Knight Odds. probably very soon we should see the beginning of another great chess game. What would be the starting 3 moves for the mirror Alekhine opening ? I believe that this time you should take the White pieces and let Komodo Dragon2 MCTS chose whatever Opening it select for Black instead of the mirror Alekhine forcing White to play with 1. e4 ?

A more interesting experiment would be for Komodo Dragon2 MCTS to give you a Knight odds, but the White pawn on the first move can NOT move beyond the third rank, so either 1. e3 or 1. d3 or you can chose to move either of your Knight

I think you are confused. "Mirror" Alekhine doesn't mean switching colors, that would be ridiculous to increase the handicap. It means switching which White knight is removed. So g1 instead of b1 removed. By the way, with b1 knight removed, the best opening move for White is probably 1.Nf3, so not allowing 1.e4 and 1.d4 does not increase the handicap. With g1 off, it would.

Okay Thanks for clarifying, but because the b1 or g1 Knight odds is so great for his level as we saw previously, at least he should allow Komodo to pick its first move

Well, with b1 off we wouldn't choose 1.e4, but because Chris committed to respond 1...Nf6 (instead of the "best" 1...d5) it made 1.e4 a good move. I think that after 1.e4 Nf6 (with either knight off) White can't complain about his opening move.

Yes, basically the idea was an Alekhine of the form e4 Nf3 e5 Nd5 where the engine is pretty much committed to going immediately on the offensive while the human sits back and holds, or tries to hold. I find that quite a good dynamic, also telling for the engine style. In the event of the b1-lack, it’s what we got.
