Hi Dann

Yes, Vasik did address this in his interview...

"Vasik Rajlich:

Yes, the publication of Fruit 2.1 was huge. Look at how many engines took a
massive jump in its wake: Rybka, Hiarcs, Fritz, Zappa, Spike, List, and so on. I
went through the Fruit 2.1 source code forwards and backwards and took many
things.

It is a bit of a pity that Rybka won't make the same contribution to the
computer chess community, but at the moment I must also think about protecting
my secrets. It's the eternal struggle for a computer chess programmer."
