Re: Arena website down >= 48 hrs

Fritz is most stable in my experience. ChessGUI is ok and stable. Arena would be my fav, but it is buggy. I wish others would fix it. Others use Shredder, too, but I have little experience w/ it.

Thanks - curious as to how the opening book was created or derived from?
That's a good question. I'll ask on the Leela Discord; maybe they'll answer.

Re: Trying out the Leela Hybrid engine (NN with AB)

0.5 is looking good, KillerDucky, but game 12 threw an exception for me.

If you downloaded that PGN before I posted this message, you should download the file again. Found an error and fixed it. Link is the same.

...It happens with v0.4 if you do not use Syzygy. Fixed in v0.5!

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

...Deep Mind's claims also hinge on the conditions, not least of which is that they ran AlphaZero at roughly a 900 to 1 NPS handicap. Not a fair comparison of the engines at all. I wonder how it would have gone if the hardware were more comparable. When I use dkappe’s Leela ratio to equalize GPU to...
