it didn't work for me.
i tried it in both chessprogram and my draughtsprogram.
Searched a lot deeper with draughtsprog, but to no avail.
in draughts one in zugzwang loses game simply, only goal
of draughts is to get zugzwang...
for chess: use nullmove and recursively.
with next double improvement:
if( previous move nullmove
&& 2 moves ago nullmove )
don't allow nullmove now
and of course don't allow it when in check, that's it!
