I think that testing contempt 150 for dragon CCRL may be a good idea

[Chessqueen]

Unfortunately I am afraid that I will get all draws in 5+3 time control when I use normal setting.

CCRL got 32 draws for Stockfish15 against Dragon3 and they do not use the opening position that I guess is even going to give more draws then using some opening book.

With a single core they got 64 draws

https://ccrl.chessdom.com/ccrl/4040/cgi ... _15_64-bit

5+3 time control is something between their blitz testing and 40/15 time control.

So far I have played 7 games between Komodo Dragon Contempt = 11 Vs Stockfish 22050407_x64_avx2 at T/C 15/10 and the score is 4 draws 2 winS for Komodo Dragon and 1 win for Stockfish, So far Contempt =11 is showing a good result , this tournament will continue up to 300 games using 4 cores.

I am surprised if you get 3 wins out of 7 games.
I got only 1 win out of 10 games with a faster time control of 5+3 from the opening position.
15+10(4 cores for every engine is close to 40/15 CCRL time control when they get always draws.

And out of the 1 win that you got using Komodo Dragon 3.0 using Contempt 11, after your 10 games what was the final score?
The score is dead even at the moment after 12 games 8 draws and 2 wins for each

This is how most of the games end up drawn and they are boring long, which I have to adjust when i see the score 0.00

5+3 time control is something between their blitz testing and 40/15 time control.

So far I have played 7 games between Komodo Dragon Contempt = 11 Vs Stockfish 22050407_x64_avx2 at T/C 15/10 and the score is 4 draws 2 winS for Komodo Dragon and 1 win for Stockfish, So far Contempt =11 is showing a good result , this tournament will continue up to 300 games using 4 cores.

I am surprised if you get 3 wins out of 7 games.
I got only 1 win out of 10 games with a faster time control of 5+3 from the opening position.
15+10(4 cores for every engine is close to 40/15 CCRL time control when they get always draws.

And out of the 1 win that you got using Komodo Dragon 3.0 using Contempt 11, after your 10 games what was the final score?
The score is dead even at the moment after 12 games 8 draws and 2 wins for each

This is how most of the games end up drawn and they are boring long, which I have to adjust when i see the score 0.00. I have observed thousands of Komodo Dagon Vs Stockfish games and with the default Contempt of 16 every time that Komodo get a small advantage of let say 0.80 to 0.90 Komodo Dragon with the default Contempt of 16 somehow stop putting pressure to Stockfish, so for a long time I had this idea that I would change Komodo Dragon to be a little bit more aggressive, and just a few days ago it occurred to me that I should probably lower the Contempt to either 12 or 11 and so far my intuition was correct; and even playing with the Black pieces it still manage to neutralize stockfish, even playing with the Black pieces [/size]

I did not use contempt 11 but I have no reason to believe contempt 11 will score significantly different than default.

5+3 is faster than 40/15 so stockfish got one win.

I consider testing 40/15 to make it equivalent to CCRL to see if I also get 100% draws with no opening book for 4 cores.
unfortunately I will not be surprised by 100% draws and to get more interesting games I need to increase contempt for Dragon but unfortunately it makes dragon losing.

I am not sure how many nodes per second I need for equivalent time control to 40/15 CCRL

[Chessqueen]

I will also start testing at T/C 40/15 with Contempt =11 to see how many draws I get after 100 games.
