Test results:

AH_tactics:

- LC0 28.2 186/250
- Hanse LC0+Stockfish 231/250
- BenBlack Stockfish+LC0 234/250
- GoratschinChess 244/250
- Stockfish 14.1 239/250

eigenmann (endgame):

- LC0 28.2 81/100
- BenBlack Stockfish+LC0 92/100
- Hanse LC0+Stockfish 93/100
- GoratschinChess 95/100
- Stockfish 14.1 97/100


Each of the 3 methods presented for combining LC0 and Stoskfish improves the result of tactics and endgame tests. None of the programs are running fully stable. The only stable hybrid I know of is HeadUp. But it only runs one engine at a time (either Stockfish or LC0).

To be more precise : only versions 171, 172, 173 and 174 have a crash after 2 moves.

Yea it's crashing for me as well after 2 moves I'm using the Cuda one. It's also the latest build.

I used the version from a month ago with difficulties. The latest version is not suitable for testing at all. It doesn't even start. Doing the analysis of one game works, but when I load another game from the database, the Stockfish windows close and the program does not work.

It looks like the stop and start instructions are missing at the right time for the auxiliary engines. Although I have no idea why the windows are closing. It's like an unnecessary quit instruction. I'm writing this generally because I'm not familiar with uci commands.

Lc0 179 does'nt work (in nvidia-cudnn environment)

C'est très décevant : Lc0 180 (comme Lc0 179) se bloque dès qu'on lui adjoint un programme pour l'aider.
Toujours en nvidia-cudnn environnement.
