Fizbo 1.9 has just been released.
It can be downloaded from https://sites.google.com/site/fizbochessengine/

Here are changes from version 1.8:

1. minor bug fixes: Fizbo 1.8 sometimes crashed when using 6-piece syzygy tables; that should not happen any more.
2. minor changes to search.
3. extensive changes to evaluation.

Expected playing strength is approximately +70 ELO vs Fizbo 1.8. Mostly due to new evaluation features.

Youri.

i put this message for diagnostic purposes (and totally forgot about it). It should be printed in case of timeout, and should not impact anything. So just ignore it, and i will take it out in the next version.
