DON Chess Engine

[mar]

Evaluation Enhancements:

More accurate pawn structure evaluation including isolated and doubled pawns.
Improved king safety evaluation and mobility factors.
Enhanced tuning of piece-square tables for better positional play.

how did you manage to do that with a NNUE engine? you must be a magician perhaps you hand-edited the weights?
also some net archs can't possibly learn mobility. perhaps you copy-pasted the improvements from a wrong version of fish?

Very likely a leftover from one of the former versions from many years ago,
when Stockfish still was using its handwritten eval.

I seem to recall that Marco took one or two code changes from DON back then, but that was it.

Engine not working. Engine load Error.

You have been told about the issue with your engine by Marco for quite some time. Still you have not fix it.

I don't think you should post any more updates, until you have fixed the problem.

Stop wasting people's time!
