I guess if anything ... this shows the importance of bug free code in a chess program. I think the first to show that was Fruit. While it is nice to have many features and many minor little tweaks to get the program to play "proper" chess ... bugs are the Achilles Heel of any chess program. Each add...

The problem with that is that when you do not know how to convert 'certain wins', they suddenly become a lot less certain... Your statement also bypasses the fact that win probabilities as determined by the NN are not infinitely accurate, but are necessarily polluted by a great deal of noise. So in...

The sad truth is that there are just way too many games like that with Lc0 and while in this case the end result was still a win for Lc0 … on many occasions there is a draw or even a loss, in what was a winning position. It is behaviour like this that makes Lc0 useless as a stand alone chess engine ...

I think if you wanted to create a network for Lc0 that plays really well at Knight odds is to train it to play without the Knight. I think it will very quickly figure out the best chances in the position and play much stronger than if it was simply playing with a network trained on the normal start ...

I think throttling of the GPU was the cause of a few lost points for Lc0 in TCEC 14. There were a few moves that simply made no sense and I was using the same network with similar hardware. It might actually make sense to have some sort of water cooling for the GPU's.

Theoretically, a powerful book will beat any other engine without a powerful book. I think a powerful book takes away from an engine playing chess as it depends completely on the book maker's ability. Better would be to have an opening and both sides have to play colors reversed.

Maybe thermal issues and GPU is throttling?

TCEC is just an entertainment venue for chess engine lovers. It probably will not give you the most accurate indication of the strongest chess engine as the opening positions are designed to be unbalanced to make as many decisive games as possible. One of the main reasoning behind opening book choic...

Finally got it working ... it seems that v4 has a bug and v3 is ok. I tried a few positions form my Lc0 Good and Bad where I did a tourney and chose a few positions where I thought Lc0 missed easy tactics and drew or lost games. Looks very promising although I think that somehow SF is not going very...
