Good results for the Bringer, however, don't overestimate its strength after a
few games. Playing it against the top engines (commercial and freeware) will
give you different results.

Someone else (Peter Berger) mentioned this some days ago, unfortunately, I am
unable to reproduce it. Bringer claims a draw, both when playing it in its own
GUI and as a winboard engine. How do I reproduce the bug? BTW, was Bringers
score 0.00 while repeating the moves?

Do you mean a possibility for Bringer playing a position agains Bringer? I had
this once, broke it a year ago and didn't care about repairing it: the
"Computer-Computer" button is disabled. I don't think this feature is important
with the possibility to interface Bringer to other engines per Autoplayer or per
Winboard. Is it important?

I thought about small "recent-squares-indicators", instead of flashing the
squares. Maybe a thin frame or a dot. If I have time, I will implement this for
the next version.
