Hello,
Should you be interested about LLMs and chess capability, I point out an amazing (and fully working, rules compliant) chess engine: Nostradamus by David Carteau.

A nice game reported here.

From my tests, v0.4 CElo is slightly under 1300 playing opponents using 15s/move (whilst Nostradamus only plays instant moves); can be a fun opponent for our weak chess computers.

A must try!

n.b.: it is a Python chess engine, native install process is a bit cumbersome but the above thread provides explanation. Worth the effort!

Grüße,
Eric
