I wonder if you all have Windows 10.

I have Win 10.

I will look into time losses right away.

About +90 ELO on 4 cores: this is difference in playing strength between fizbo 1.6 running on 1 CPU core and fizbo 1.6 running on 4 CPU cores. Many top programs show larger increase 1 CPU vs 4 CPU.

No, Windows 7

Fizbo 1.6 don't qualify with Owl Rating List.

Too many time forfeits. More than 50% in 100 games under Windows 7/8.1/10. Also don't run under Linux with Arena.

OK, i found the problem and fixed it. Corrected executables are uploaded to my site (https://sites.google.com/site/fizbochessengine/).

The problem was that i accidentally removed code that verifies that SYZYGY files are in place before using them. As a result, engine tried to open files that don't exist, and crashed.

I did not see this problem in my testing because i always had SYZYGY files in place.

Youri.

Thanks Youri,
works here okay now.
