Ok thanks, I'll fix that !
But I'm not sure what wouldn't work following protocol 1 spec ?

MOVE
version 2:
usermove MOVE

Still awesome that even with so few lines, it still would have been the strongest engine back in the late 90s/early 2000s.

Well, I must admit this is just developing for fun (re)using what pioneers already tested back then and what is already working well on top engines. The real great part in the process is learning about chess, chess programming, re-discovering things by myself and sharing with the great chess programming community. I am still amazed about how kind everybody is here, spending time sharing, testing, searching and teaching.

A +50 elo tweak is always nice, well done.
For my engine, probing the TT table in qsearch (but not storing in TT in qsearch) was the best. How about for you?

Using TT in qsearch was useless in Minic with a very simple eval. It became good to store and probe in qsearch when eval started to be the bottleneck.
Just probing TT in qsearch seems strange to me, this will only be good when in check I guess... I store things in qsearch with depth=-1. I guess the important thing is to get eval score for free, I don't expect a lot from TT cut-off.
