Ok, I understand now - thanks.

But from a analysis (for an "normal" human game!) I will know what, say me a
program for move "Y" and for move "X" in deep A+B+C. Tiger say here not the
score for e5 in deep 14, only the score for Bd5. Other programs gives better
(and more) variations than the Tiger, or not?

(sorry for my bad english, in german I can this besser articulate!)
