I submitted a couple posts regarding the polyglot engine adapter (which I'd like to clone from Muller's git repository and customize). Could you please check if they got caught in the spam filter?

Thanks in advance.

Well done! I quite enjoyed the engine description as well!

Your web page mentions EloStat. I have a Stockfish fork which I'd like to test at a variety of settings, to determine its "Elo" rating. Any advice you can provide would be greatly appreciated.

I don't claim to know the best practice, but a practical solution may be to allow generation of illegal moves such as BxK (which would only occur in illegal positions) and to disallow move generation when the player to move has no king.

I am interested in using the Polyglot adapter to play opening books on Stockfish's behalf. I am further interested in customizing polyglot to play variants as I have started to do so here on Github .

I have forgotten how I managed to git clone the polyglot repository in the first place, and from ...

As maintainer of the Stockfish fork used by lichess, I'm unfamiliar with that user.
