2 noticeable facts :
1) Fruit 2.3.1 perform very well for a free engine.
2) Zap!Chess Zanzibar perform very poorly.

My theory for this is that the book is the main thing here : Zappa is not very good in opening position and Fruit is good ...
But it's only my theory ...

Hi Vincent,

here are the current ratings of these engines in the CCRL 4040 lists.
Zap isn't that bad as you can see. It's probably just having a bad tournament.

Regards, Graham.
