Fun fact: in one of the games, my engines reached the KBN-K endgame, so this does actually happen. Since it doesn't support EGTBs, it's good that it has some KBN-K code to win this. Indeed sometimes this happens. I don't think that my engine is capable of winning this without TB. Actually I never t...

It was a remarkable tournament, probably one of the hardest monthly tournaments ever. I didn't expect Nightmare to win this tournament with LCzero and two RaspberryPI's tied for 2nd place. The difference in strength between the numbers 1 to 14 is probably negligible. Six weeks ago I've implemented a...

In every iteration I change the 300k pos by first shuffling the 1m+ training pos randomly. So you are using mini-batches for training. Is it a standard for Texel tuning or using a batch size equal to the size of the training set is also fine? (leaving time considerations aside) Using a batch size e...

To be honest I have the feeling that development tools under Linux are so cumbersome compared to Visual Studio that I don't want to step away from it. When I really like a piece of software I'm always willing to pay for it, I don't want everything for free. I have that feeling with visual studio: "...

The point is that it is all bull sh*t, with so many threads on slow CPU's the engines will only degrade.

In my case, with regard to development tools, I refuse to use anything that is paid or not cross platform. I don't want to write an engine that needs a huge code change to run on Linux or the Mac (even though I'll probably never have a Mac), and I don't want to change editors if I should ever switc...

It all depends very much upon the quality of the evaluation-function and the quiescence-search. When you play a game against an engine with aproximately the same strength the root-score will deviate only a few centipawns during the whole game and you can set a very narrow window without having to re...

I'm developing under Windows with Visual Studio and use 3 compilers: MSVC 14.2, CClang 10/11 and the new Intel oneAPI C++ compiler. On average there is not much difference between the 3 compilers, when I target one of these new Intel >= cascade-lake processors the Intel compiler clearly wins, for AM...

I am looking at: https://github.com/nodchip/Stockfish/blob/master/src/learn/gensfen.cpp The question is - it looks like by default it occasionally inserts a random move into the played games to increase variety. But then when the game is ended, it assigns the same result to all the generated FENs f...
