That's silly. Having two engines draw 500 times does not mean one definitely is
a clone of the other. It means that they are roughly even in strength. Using the
facade of a chess engine IMO is nothing like cloning it. A clone is taking the
same code, eval and all, and changing the name.

It is a bit like saying that a Mustang Saleen (to make an automotive analogy) is
exactly like a stock Mustang since the body is the same. In reality, the former
is a version of the latter which has been gutted and had the entire engine
replaced. In other words, the ONLY thing that they share is a frame.
