Yes, I try hard. Obviously to get some support from who is already there, in the
summit of it, is tremendously exciting.. :-))

But that was not the point, my friend. Nobody discussed such an evident fact.
The question was and is IF that portion was enough to say "this is just a bloody
clone..."

Well, all the problem resides precisely in the fact not enough informaton is
available. We had been both you and me and all people here debating on the
ground of speculations.

Wait:
a) If they put a lot of effort and changed evaluation functions,. I would say
that's enough to talk of another program
b) Yes, they kept the search function, but -am not sure- that fraction could be
considered as a kind of general tool as alfa-beta, prunning, etc are. Specially
would be so if the author, as he has did, made it available.



That is my only point. No proof. No

Without oposition, no discussion; without discussion, not necesity of CCC.
Without CCC, we will get bore.
