OK, I have a question:

No suppose you test program A with book A against program X with book X and you
get a very good score.

Do you call this a proof that both the program A and the book A are good?

If yes, then you test program A with book A against program B with book B and
the score is still very good!

Then this is a further proof...correct?

Now you test against program C with book C and program A get killed!

Then you show the games to a very strong player which is friend of yours and he
immediately tells you that book A and program A are weak because they play weak
and the reason it won against program X and B is because they did not reply
correctly to weak moves...

At this point you find out that the only TRUE finding is that program A with
book A are weak and can score good only against WEAK opponents...

Do you still call this "only sure proof"?

Analyse games seriously is the only way to draw some logic conclusions...believe
me!
