Seems not much stronger, may be 15-20 elo, but I expect it to scale better at longer time controls or with more processors. Will see

Muchas Gracias my friend. When you say is 15-20 elo stronger, I suppose in reality you mean it is 50 elo or more we can count on in long games.

If somehow I had recovered some scaling I do not discard something bigger than 20, but is just impossible to test this as you know. I prefer to not have any special expectations. Will be nice for example that CCRL 40/40 will have more elo than 40/4

I know that you have more than 15-20 elo improvement up your sleeve.
In long games and on more cores you can add 30 more

Awesome! I'll test this shortly.

Thanks Daniel.
Seems like slow, but sure progress.

Thanks Daniel.
Seems like slow, but sure progress.

The aim of the version is to try if without much modifications, mostly hand tuned stuff, I'm able to improve the long time control clearly. Is for this that I published it without much improvement at my basic testing time controls.

Next version I should publish with more improvements or at least less often; if not I will drive crazy all kind testers like you

Nice to see another progress of your engine. Do you plan to add support of syzygy tablebases? Andscacs does not understand e.g. rook endings where white has a+c pawns and it is known draw, but evaluation is +2,45 for a long time.

Thank you, Daniel !
