Some handicap results and conclusions.

[JJJ]

Lyudmil I like so much how constructive you are in helping Komodo to improve.

[Lyudmil Tsvetkov]

Lyudmil I like so much how constructive you are in helping Komodo to improve.

come on, Larry will say he lost another 10 elo on this.

[JJJ]

You know you re a genius friend, you just paranoid sometimes and have your weird sense of humor

I think you re right about Stockfish winning against Komodo and the way he does it most of the time.

Your suggestions and ideas are always welcome. Even if 95% of the time they are not helpful, occasionally something you say inspires a change that gains one or two elo. I'm pretty good at judging which of your ideas are worth testing and which are not. So thank you for your contributions.

[lkaufman]

I don't know why I am posting this, Larry might be angry, but the doubled g3 pawn is so typical of Komodo, that I thought it is worth a post.

here is a game between Komodo 10.1 as white and SF:

SF 20cps black advantage, Komodo 40cps white edge.

quite probably, white is already lost.

see how SF fixes the g3 doubled shelter weakness, and then h5-h4 uses the weakness to open lines for decisive attack.

I guess tuning engines against only their predecessors is a bit shaky concept, as Komodo playing against its predecessor might never utilise effectively the g3 weakness, no matter the statistically significant number of games.

but then, the doubled g3 shelter pawn is maybe Komodo's pet flaw.

On my laptop, current Komodo takes only a few seconds to show a zero score. The search depth of 15 you show is extremely low, even for a bullet game; do you have a very old or even 32 bit computer? My laptop gets to 20 ply in a couple seconds in this position. Aside from that, the more interesting question in this game is the pawn sacrifice on e5 played by Komodo; although it gets fair comp, I think most GMs would not offer that pawn. Maybe another example of Komodo's generosity. As for the g2/g3 pawns, you are correct that Komodo values them more for defense than do other engines, I think correctly so. they do a great job of keeping enemy pieces out, True, they provide a "hook", but you can't have everything. Perhaps we should find a way to lower the value of the second pawn a bit.

[lkaufman]

another one.

this probably has to do with depth and move ordering/general search.

SF 70cps white edge, Komodo 0.0.

this is quite indicative.

most SF wins are like this.

Here in the diagram position current Komodo on my laptop takes less than a second to see a solid White advantage, so again the problem is some combination of the old Komodo version, your hardware, and the bullet tc. Because of your slow hardware, I think bullet games are too fast to be useful.

[Lyudmil Tsvetkov]

I don't know why I am posting this, Larry might be angry, but the doubled g3 pawn is so typical of Komodo, that I thought it is worth a post.

Maybe another example of Komodo's generosity. As for the g2/g3 pawns, you are correct that Komodo values them more for defense than do other engines, I think correctly so. they do a great job of keeping enemy pieces out, True, they provide a "hook", but you can't have everything. Perhaps we should find a way to lower the value of the second pawn a bit.

the position is simply lost, so score is more like 60-70cps black advantage.

whatever my pc, both SF and Komodo are using it.

g2/g3 doubled pair is simply no good, when the pawns are within the king shelter.

with b2/b3 combination, this is just fine.

problem is related exclusively to king safety.

do you distinguish between such pawns, when they are within the shelter and otherwise, or just have a general psqt for pawns/doubled pawns?

[Lyudmil Tsvetkov]

another one.

this probably has to do with depth and move ordering/general search.

SF 70cps white edge, Komodo 0.0.

this is quite indicative.

most SF wins are like this.

Here in the diagram position current Komodo on my laptop takes less than a second to see a solid White advantage, so again the problem is some combination of the old Komodo version, your hardware, and the bullet tc. Because of your slow hardware, I think bullet games are too fast to be useful.

same PC, same TC for both SF and Komodo.

the bullet games that are too fast to be useful are the same ones, you are using for testing, or at least have been using for testing extensively.

of course, we all know your latest dev is flawless, pity most people don't have access to it.

[Lyudmil Tsvetkov]

Lyudmil I like so much how constructive you are in helping Komodo to improve.

come on, Larry will say he lost another 10 elo on this.

Your suggestions and ideas are always welcome. Even if 95% of the time they are not helpful, occasionally something you say inspires a change that gains one or two elo. I'm pretty good at judging which of your ideas are worth testing and which are not. So thank you for your contributions.

you are most welcome Larry.

I wonder how you get to such a high 5% success rate, bearing in mind all of Komodo's idyosyncratic code/evaluation and the unavoidable term redundancies?

[Lyudmil Tsvetkov]

You know you re a genius friend, you just paranoid sometimes and have your weird sense of humor

I think you re right about Stockfish winning against Komodo and the way he does it most of the time.

when I win, I am a genius, when I lose, just an ordinary man.
one day you win, the other you lose, that is what chess is all about.
