New Engine: Deep Saros 2.3c3

[zullil]

Is this yet another engine created from the stolen Rybka code?

If the clones can easily be proven to be tweaked versions of Rybka (eg using large portions of code that didn't exist before Rybka was published) then why doesn't Vas take legal action against the "authors" of these other engines?

I interpret this as "yes." "No" does not need such contortions.

If the clones can easily be proven to be tweaked versions of Rybka (eg using large portions of code that didn't exist before Rybka was published) then why doesn't Vas take legal action against the "authors" of these other engines?

What should he list in the charges? "These people stole the code I took from Fabien Letouzey's commercial product?" Or possibly "These people stole the code I took from an open source project?"

My understanding is that Rybka was once largely a derivative of Fruit, commercial or open source. Either way, a lawsuit seems like a case of the pot calling the kettle black.
