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.

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

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.

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.

Hi Fabien,

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

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

Thank.
