Berserk 8 Released

[jhonnold]

Great fight for number 3. position: SlowChess, Koivisto and Berserk! BTW Koivisto is the only one, that works 100% in old Fritz GUI .

Is the old Fritz gui still obtainable? I can look to see why Berserk does not work there.

[Jouni]

Berserk (what a name!) plays games without problems in old Fritz GUI. Running testsuites is not working. But it's common problem with many engines. No big deal at all. Same happens with Ethereal, SlowChess and Arasan et cetera.

The MoveOverhead default value 300 is weird. 300 ms? How You can play 8.0+0.08s games? SF has 10 ms overhead.

The MoveOverhead default value 300 is weird. 300 ms? How You can play 8.0+0.08s games? SF has 10 ms overhead.

This is not per move - it just means Berserk will avoid letting it's time dip below 300ms.

Aha OK. Test match against SF classic (last HCE). 60 + 0,6 HERT openings:

Hi, the avx512 compile crashes here (CPU 11800H):

Thanks for reporting this Werner. I'm going to remove the 512 binaries for now since others are having issues as well.

[Werner]

perhaps Koivisto author can help? His AVX 512 compile runs fine here!
