My games played against Rebel 10 with altered books and mainly without books and
I have found Rebel 10 lacking greatly. Without its opening book I find Rebel 10
to be somewhat a weak engine. Rebel also gets into time trouble alot of the
times makes bad moves due to lack of time.

But with its books Rebel 10 plays a mean game of chess. But from pure chess
engine power so far. CM6K and Shredder 2 have given Rebel 10 quite a beating
without opening books.

And with opening books CM6K is still ahead, but Rebel is beating Shredder2.
