Re: New engine releases 2019

Nemeton 1.81 from the link in my signature below. Kind regards, Stan Thank you, Stan. Judging by the version number the changes are minor. What are they? Hi Gabor, Usual code optimisations but the main thing is a nullmove trick. I reduce an extra ply if static eval is significantly out of window. C...

Re: The Elusive Creature

Thanks for the tournament Graham!

Good result for Nemeton 1.8 and something of a milestone: it has scored better than King of Kings. One of my favourite engines of all time and one that back in the day seemed impossible to ever catch up to.

Re: Testposition and HUGE fail high from Stockfish!!

I've always liked this one. Not sure of the source.

White to move Bc7 is mate in 11. (?) If you force Bc7 engines will give a huge queen up score for black till they see mate which is not easy.

Re: Nemeton 1.7

Had a Heisenbug. That disappeared when I tried to find it in debug mode or when changing compiler version. Noticed my node counts were different in certain positions in debug mode but nothing breaks. Then I compiled some ancient versions of Nemeton and the problem has always been there. Yikes the st...

Re: Nemeton 1.7

What GUI is that? Every GUI I ever tried got this right ofcourse and promoted to queen when unspecified. Nemeton only sent a suffix with underpromotion. I remember doing that for a reason but who knows what that reason was. So I updated the archive to something that sends a "q" on queen promotion an...

Nemeton 1.7

I updated the link in my signature to Nemeton 1.7. Bugfix to stop it being unintentionally blind in simpler endings. More aggressive pruning. Tried this before but with other changes it now actually kinda works. More compact bits of code. In Nemeton3D the queen and knight are improved as well as som...

Re: Square Off

Most likely the Square Off app will improve now that they finally managed to deliver to their backers? They have been mentioning Chess.com at the very least. My kingdom set arrived this week. I like it. Some minor quirks and I can't help but fear for it's longevity though I have no reason to do so b...

Nemeton games

Nemeton had a good run this edition. Starting off with an upset win against Amoeba and a draw against the much higher rated WaDuuttie I also can't complain about. Besides luck I also made some small improvements this week. I have updated the link in my signature to version 1.61. [pgn] [Event "ICS Ra...
