Let's pause for a moment and consider Olithink.
It does not give a damn about King safety. You can pile wood around the king until the cows come home and he won't flinch.
Bishop pairs? Who cares?
All the eval terms we know and love are nothing.
And yet, it is about Glaurung strength. That is (quite frankly) absurd and flies in the face of chess knowledge painstakingly coded into most chess engines.
I paused the development of OliThink in about 2010 with an ELO of 2370.
This year, I restartet it and now it's about 400 ELO stronger, but: There has been hardly any change in the evaluation function. It's the same mobility stuff and the engine still has no knowledgde about "doublepawns", "castling", "7th file", "outpost", "delopping light pieces first" etc.etc..
Mostly the search has been improved and still has some bugs. More aggressiv pruning leads to more missing of important lines, but paradoxically the ELO gains.
