Re: Hash collision?

Although the likelihood of an incorrect cutoff affecting the search in a meaningful way seems small, would it be worth verifying other aspects of the hash entry to reduce collisions? For example, checking that the stored move is pseudo-legal.

Yes, Syzygy wasn't used there.

Perhaps it's to do with one of your interior node recognisers? Topple doesn't have any of those yet.

Re: gcc and g++ 9 are available for msys2

GCC 9.1.0 generates an executable of pretty much the same speed for me.

Re: gcc and g++ 9 are available for msys2

I didn't know msys2 existed - I've been stuck on mingw-w64 with an outdated gcc version until now.

Re: Swiss Tournament Ed.VIII. Group C.

~snip~ ~snip~ Looks like this one is my bad. It seems to be related to this issue: https://github.com/konsolas/ToppleChess/issues/21 I've only tested with 6-piece tablebases and with automatic adjudication, so it seems like I've overlooked some issues which occur when 5-piece tablebases are used wi...
