I do not think Rybka is a clone but if you turn distance pruning off in Fruit
2.1 you will seem some similar endgame bugs.  I think this is a coincidence
though.  Also is you look at the way Fabian made makemove if Fruit it would not
be hard to switch to bitboards and keep a lot the same elsewhere.  There are
other flags like crashes where Fruit would give an error and similar engine
output but I think both coincidence and possibly even rewriting some bugs from a
good reference in his own code are the likely reasons for this.
