Re: Possible "real" hash collision

If they don't exist, why then verify the tt-move? maybe because of race conditions when multiple threads work on shared TT? (I'm paranoid enough to do it in single-threaded search as well because my makemove would crash on invalid move) the effect of hash collisions along with the impact on root mo...

9 of 9 "real" hash collisions are either a fantasies or bugs
why do you think kh2 a blunder? the position is lost anyway

Re: CCRL 40/40, 40/4 and FRC lists updated (4th May 2019)

I could do a blitz test for v2.0.1 if you like, Folkert, but the exec you provided crashes instantly on startup here. That's odd, I did not change anything in the compilerflags and I'm not using any asm. I've recompiled it without -mtune=native and it runs on my pc at work (core i5). So there's a n...

win-chance for each root move

Hi,

I'm looking for a list of win-chances per move in the starting position.
Like, historically playing b2-b4 gives you a 18% win-chance and e2-e4 51% (I made up those numbers).
