Re: New Tool for Tuning with Skopt

I've run the script with my xboard engine, but I don't set usermove=1. I do get timeout errors loading the engine, despite it taking well less than 1 second and sending done=0 and done=1. Nevertheless, it runs anyway.

I am afraid It is not your typical epd encoding, it has historical (dumb) reasons why it is not. It should still be pretty easy to parse just split every line at "|" and you can extract FEN and Game Result.
