Havoc - New Gothic chess engine

[hgm]

If you are ready for stronger opponents than Fairy-Max, you can try some of the other Participants of the last Battle of the Goths (already 9 years ago! ).

Hello!
Thanks, once I get to 90%+ then I'll switch. Also my plan is to venture to other variants pretty soon. As Havoc has very flexible design.
Right now I'm figuring how to gain more ELO from extra threads. I'm gaining tons of NPS but very little ELO atm.

Polished my Capa/Gothic engine to perfection.
Super fast/super stable.
Just beautiful simple/fast code.

Added NN-evaluation. My training set is only 20,000 fens. Generated from Havoc games. MSE is yet to be squeezed down... Too little. Still Havoc already is crushing.

A few interesting games.

Old net + 2 threads: 2x faster a little bit deeper.
