I see no reason for the assumption that dynamic stuff is better than combination of static stuff and dynamic stuff that stockfish has.
Personal experience tuning everything on hand.

Re: Top Engines without Piece-Square Tables?

Are there any engines above, say, 2700 that have eschewed the use of piece-square tables? Edit: Excluding neural nets. If Stockfish removed them, they will probably need to add some positional parameters and retune everything to compensate. I suppose that it will become a little stronger, as dynami...

Re: Killers and forward pruning test searches

Killers are very local. Some engines even enforce that (presumably because it was shown to gain Elo) by explicitly clearing the killer slots for the daughter level when they enter a node. This means you could never inherit a killer from any node other than a sibbling in the same search. Then the si...
