The right thing here is to setoption name Move Overhead value 1500, i.e. the option is exactly there to inform about expected (worst case?) GUI delays.

Receiving negative (even including zero) btime could lead to all kind of weird stuff. This is really a GUI bug.

Aloha! From where this comment comes? I lost the trace.

Ha !
You got me - I dont think it was TalkChess but maybe referenced by/to another Forum where vondele seems to be active.
Maybe Discord but I dont think thats where the comment was made.

I just made a copy of his comment and had it on my desktop.

In Stockfish, simple eval (evaluate.cpp) has now been removed.

Remove simple eval

Now Stockfish solves the two critical positions immediately, for which I had previously criticized Stockfish.

Unfortunately, Stockfish 090224 now has problems with this position:

That's why I'm going to change the parameters for the small network again. It will look like that:

Yes, I like that better. I will continue to optimize and then implement the optimizations into my own engines. Stockfish X is just an initial test version on the way. My own new engines run with Random Op. MultiPV 2, and have no problems with this and other positions, but Stockfish dev unfortunately has some problems here.
