Weiss 0.7 released.
This version mostly improves search by better move ordering and adding pruning heuristics. More details in the tag.

That's fine. Unfortunately I am still not trained to compile it myself. May I ask for some Windows executables?

Thanks Günther.
I have tried to learn to compile these myself several times but failures led me to lose my interest. Waiting for the kiss of the muse.

I've added 3 windows compiles to the tag. Feedback on whether they work or not would be appreciated

Thanks Terje. All three work for me. Under Shredder 13 I measure the following approximate speeds:
nopop: 1250 knps
pop: 1360
pext: 1430
Günther's compile: 3420 knps

oops :)
I can confirm only that my compile is around three times as fast as Terjes nopopcnt version.
(ca. 600kn vs. 1.800 kn on my hardware - only measured from starting position at higher depths)

Oh, I forgot the O3 flag
I've reuploaded new versions with it. Hopefully these will be comparable to Günther's
