Komodo Dragon vs. GM Perelshteyn, knight odds match.

[lkaufman]

Our next human opponent for a handicap match with Komodo Dragon will be GM Eugene Perelshteyn, born 1980, current FIDE 2494, peak FIDE 2555 in 2008. He has been above 2500 FIDE for most of the past 17 years, has played two previous matches with Komodo, and is training with a copy of Komodo Dragon 2.5.1. He is a chess pro, developing a course for chess.com and coaching. The handicap will be full knight odds (alternating b1/g1), standard scoring. Time control as usual Rapid 15' + 10"; however in a new twist Dragon will be set to play as if it were blitz (3' + 2"), so five to one time odds on top of the knight odds (clocks won't show it, but it will be obvious that Dragon is playing blitz)! We'll use the latest dev. version of Dragon (a slight upgrade from 2.5.1), with a handicap book and whatever settings seem optimal. Hardware probably my 32 core Threadripper. Games to be played on chess.com on Nov. 6 starting 11 a.m. Eastern Time. Six game match, total playing time shouldn't exceed 3 hours, total match time probably not more than four hours with time for brief comments after each game. Perelshteyn streaming, but due to the time odds he'll be on move most of the time so may not comment much during actual play.
This will be our third attempt to give knight odds to a Grandmaster in 15' +10" Rapid. The first match, in May 2020, was with GM David Smerdon; Komodo lost 5 to 1, but that was regular Komodo, before Komodo Dragon with NNUE existed. The second was with GM Anthony Wirig, in July 2021, with Dragon 2.0. Because we had agreed to Armageddon scoring, where draws counted as wins for Dragon, Dragon won by 5 to 4, but with normal scoring Wirig won by 6 to 3 (4 wins, 1 loss, 4 draws). All three GMs were rated very close to 2500 FIDE at match time (the rating required to earn the title normally). Since Dragon 2.5.1 is stronger than Dragon 2, and since we did win the Wirig match with Armageddon scoring, I felt that it was time to try our luck in pure knight odds Rapid. In the Wirig match we already set Dragon to play using roughly half its time, and I decided we can increase the time odds because super-precise play isn't really helpful down a knight; according to simulations I've run. It just doesn't help to use more time than in a blitz game under these conditions. So I'm hopeful we can at least do better than the 33% score vs. Wirig; whether we can tie or even win the match is another matter entirely. I'm confident that we will win a knight odds Rapid match from a 2500 GM before long, but this might be too soon. We'll see.

1)Super precise play does not help when you are down a knight but during the game you are not always down a knight and I guess super precise play can help when you are down a pawn at least in ponder off games against engines.

If you have more time it does not mean you use it but only you use it only when you need it so after seeing that the opponent's advantage is small enough you can use more time.

2)The game is not ponder off so practically the advantage of using less time is that the opponent is going to play worse but you can play better with more time if you use more time correctly.

If Komodo Dragon Win this match with GM Eugene Perelshteyn https://ratings.fide.com/profile/2012529 practicing with the previous version 2.5.1 it would be an amazing performance for Komodo Dragon.

I played 4 (2 Games) Dragon (1Thread) matches with:

Joker (1 Win, 1 Lost)
Zarkov (2 Lost)
ChessTiger (1 Win, 1 Lost)
Colossus (1 Win, 1 Lost)

1 Game without the b1 knight and the other without the g1 knight. I really don't see the GM winning a 6 games match on your system (Save the Armageddon scoring).

I played 4 (2 Games) Dragon (1Thread) matches with:

Joker (1 Win, 1 Lost)
Zarkov (2 Lost)
ChessTiger (1 Win, 1 Lost)
Colossus (1 Win, 1 Lost)

1 Game without the b1 knight and the other without the g1 knight. I really don't see the GM winning a 6 games match on your system (Save the Armageddon scoring).

Why do you believe that those four engines are a reasonable simulation of a human 2500 GM? I'm not saying you are wrong, just want to know your reasoning.

Our next human opponent for a handicap match with Komodo Dragon will be GM Eugene Perelshteyn, born 1980, current FIDE 2494, peak FIDE 2555 in 2008. He has been above 2500 FIDE for most of the past 17 years, has played two previous matches with Komodo, and is training with a copy of Komodo Dragon 2.5.1. He is a chess pro, developing a course for chess.com and coaching. The handicap will be full knight odds (alternating b1/g1), standard scoring. Time control as usual Rapid 15' + 10"; however in a new twist Dragon will be set to play as if it were blitz (3' + 2"), so five to one time odds on top of the knight odds (clocks won't show it, but it will be obvious that Dragon is playing blitz)! We'll use the latest dev. version of Dragon (a slight upgrade from 2.5.1), with a handicap book and whatever settings seem optimal. Hardware probably my 32 core Threadripper. Games to be played on chess.com on Nov. 6 starting 11 a.m. Eastern Time. Six game match, total playing time shouldn't exceed 3 hours, total match time probably not more than four hours with time for brief comments after each game. Perelshteyn streaming, but due to the time odds he'll be on move most of the time so may not comment much during actual play.
This will be our third attempt to give knight odds to a Grandmaster in 15' +10" Rapid. The first match, in May 2020, was with GM David Smerdon; Komodo lost 5 to 1, but that was regular Komodo, before Komodo Dragon with NNUE existed. The second was with GM Anthony Wirig, in July 2021, with Dragon 2.0. Because we had agreed to Armageddon scoring, where draws counted as wins for Dragon, Dragon won by 5 to 4, but with normal scoring Wirig won by 6 to 3 (4 wins, 1 loss, 4 draws). All three GMs were rated very close to 2500 FIDE at match time (the rating required to earn the title normally). Since Dragon 2.5.1 is stronger than Dragon 2, and since we did win the Wirig match with Armageddon scoring, I felt that it was time to try our luck in pure knight odds Rapid. In the Wirig match we already set Dragon to play using roughly half its time, and I decided we can increase the time odds because super-precise play isn't really helpful down a knight; according to simulations I've run. It just doesn't help to use more time than in a blitz game under these conditions. So I'm hopeful we can at least do better than the 33% score vs. Wirig; whether we can tie or even win the match is another matter entirely. I'm confident that we will win a knight odds Rapid match from a 2500 GM before long, but this might be too soon. We'll see.

1)Super precise play does not help when you are down a knight but during the game you are not always down a knight and I guess super precise play can help when you are down a pawn at least in ponder off games against engines.

If you have more time it does not mean you use it but only you use it only when you need it so after seeing that the opponent's advantage is small enough you can use more time.

2)The game is not ponder off so practically the advantage of using less time is that the opponent is going to play worse but you can play better with more time if you use more time correctly.

As usual, you make good points. Ideally it would indeed raise our chances if we played fast when clearly lost but took more time once the game was within about a pawn or so of equality, but we have agreed to continue to play at blitz (5" per move or faster) regardless of the position. Because of your second point, regarding ponder, I don't think this restriction will hurt our chances measurably; being able to take 10 or 15" per move in some even endgame might increase our quality of play marginally, but the extra ponder time might help the human just as much. Overall I don't think that this time handicap will affect the result very much considering both of these factors, but I could be wrong. Maybe in the future we'll find a better way to make use of more thinking time even in a knight odds game, but based on simulations it just doesn't help with normal engines.

I am not sure what is reasonable for a 2500 GM, however these are 4 low rated random engines that have given humans trouble in the past on 1 thread so I really don't think that your system would be easier.

Can you provide some specifics as to what those four engines have accomplished vs. humans? Are we talking about GMs (or near-GMs), and were the games Rapid or Classical as opposed to blitz?

What do they need to 'accomplish' to give a human GM or lower a hard time at rapid time controls that they have not already accomplished?

Okay, those are two good examples for those two engines. What about Joker and Colossus, do they have similar accomplishments vs. strong human players?
