bb-size = 7
bb-preload = 6

This means that the program has a 7 figure base loaded (bb-size = 7), but uses 6 figure base (bb-preload = 6). Everything should be clear now.

[Sidiki]

So Scan has 7 egdb?

Not because the engine does not have a 7 figure base only 6.

You put bb-size=7, ok

Have you Damage 14.0?

Have you Damage 14.0?

That's what you. I will write something I think, but I'm not sure how much truth is in it. Bert, the version he won with the Scan program did not make it available to anyone. Why I think so. Because I played a few games with Scan and the program was lost every time. I will write again at the end that this is my supposition and I can be wrong.

OK, that's fine

Hi Krzysztof,

Kingsrow 1.60 vs. Scan 3.0 0 wins, 0 losses, 158 draws, 0 unknowns

Is that the first time that a match ends with 100% draws?

Anyway, your tests also show what we already knew: the draw rate increases in slower games. So 2-move ballots are already too small for top programs.

Fabien.

Hi Fabien,

This is the first time I've met where all the draws are during the match of two great programs.

[Sidiki]

Hi all
It seem that programs play better when threads are high. I have right or no ?

Thank.
