Thanks Richard.

Thanks Richard.

Yep,a great release as usual

[overtond]

That sounds like 50-60 elo difference - is that correct?

Does the elo diff change as thinking time increases, i.e., does the gap in strength between C0.80 and C0.90 increase with thinking time, decrease, or stay roughly the same as the gap tested at presumably fast times {1+1 games perhaps?} used when testing the effect of changes made?

Thanks Richard Keep up the good work.

Thanks Richard, and thanks for increasing the hash size yet again!

PS: Your engine is going to be directly placed in TCEC Division 1 (more details about the new TCEC system later).
