This version is clearly stronger than 2.0. Moreover, so far I have not detected any crashes with it.

Can a new section be added for new NN Engine releases , and one just for ab engines instead of mixing them up ?

Your link is a little messed up, Damir. Not exactly a new engine either, but nice to see the old versions available.

Version 1.9.1 of FabChess https://github.com/fabianvdW/FabChess/r ... tag/v1.9.1



This version comes with a bugfix to timecontrol which sets default safety flag to 100ms. (When the time left <100ms, stop search and report move). This should hopefully prevent the crashes Version 1.9 has faced.
Timecontrol as a whole was retweaked a bit, so If anything seems off there, please let me know.

Version 1.9.1 does more uci reporting and also has some tweaked values in null move search and aspiration window. Also a bug in eval was fixed.

All in all this version is +20 Elo against Version 1.9 at 10s +0.1s games.

If there are any problems with the binaries (especially the NON-POPCNT ones), or if FabChess crashes again please let me know.
