Fruit2.1 is an old free version so of course it relatively weak but rybka with
no book can lose against weaker engines than fruit
Here is a game when Rybka with no book lost against latest Movei that is
probably more than 200 elo weaker than Rybka(it was the first game that Dan
Corbit made between Movei and Rybka under arena).
Movei was out of book after the first move but Rybka lost very fast against
Movei's king attack(it seems that endgames is not the only weakness of rybka).
I believe that after 17...Bxe5 white has a won position and even before that
move white is probably winning.
It is interesting if some strong player is going to give comments about the
mistakes of rybka in the game.
