RubiChess 20230918:

maybe, one of the most balanced (strength between mid-game and endgame) TOP-10 engines.
Like the contempt settings and my feeling is ...
Which each new version better in attacking chess against the King with many pieces on board (OK, tested with complicated Kings-Indian positions only). For that opening system indeed it seems a bit better as King-Indian expert SlowChess.

So I have a little bit to do for looking in my other favorite Dutch and Scandinavian systems.

Much more as a nice work only, thank you!!
Analyze gift!!

Best
