feeks

[Guenther]

With pypy3 it looks better now - no depths below 4 and a win vs. same opponent.

Except for the first move it reports around twice as much nps, but I am not sure how reliable the nps count currently is.

Decisive difference in that position before move 6:

with pypy3-5.11.0a0 (3.53 32-bit for Win - there is no recent for 64-bit Win)

It now does :D

Tried to run lastest master under pypy2 now for speed comparison with pypy3, but it crashes here.
Found too much hits in google for really looking at it, may be a problem with select() in Win.

error code:

Not at all!
Fully a/b with psq, material, lmr, null move, tt

No nnetwork/deep learning experiments ?
Maybe after some years they all laugh about alpha beta chess engine implementations.

Also alpha beta playing not human like chess.

Also googled for it and it may have to do with import socket being required and/or select not working for other filedescriptors than sockets (and I use it on stdin).

Maybe some other time.

Right, after regoogling I come to the same conclusion that you cannot use select on stdin in Win.

Are there windows binaries (.exe files) or the only way to use the engine is through a python interpreter?
