Re: Probe EGT in quiescence?
In search and qsearch I probe only wdl. Syzygy are compressed. I haven't tried with a shorter time control, I think that with a short tc there wouldn't be much improvement.

Re: Question to UCI engine authors
During search I handle only "isready", "ponderhit" and "stop". Handle the options would add more complexity to the engine. It's better for the engine to receive the other commands while it's not searching.

Re: Hashing a quadboard from scratch
I think it's a good idea that can worth a try. In my engine I use the zobrist hashing that is not really expensive because with the key I have also to incrementaly update the material+pst scores. I use a struct that contains all like this: typedef struct { uint64_t Hash; int16_t ScoreMg; int16_...

Of course less weights are easier to tune, but even if they are well tuned they can't express all the knowledge of a more complex evaluation.
So the answer is not so easy.

Evaluation doubt
In the evaluation function is it better to have a few weights but well tuned or more weights not well tuned?
