I say nothing about Rebel but vincent talked about most amateurs and I cannot
disagree more.

Movei has today a very simple evaluation and it beat at least half of the
amateurs.

I guess that the number of amateurs with more complex evaluation than Crafty is
less than 50 and there are more than 150 amateurs.

I even believe that the quality of the evaluation of crafty is not worse than
the quality of the evaluation of part of the commercial programs.

It is known that crafty's strong point is not tactics(for example it does not do
checks in the qsearch) and if crafty can be only sligthly weaker than commercial
programs then it is logical to suspect that the reason is tactics and not
evaluation.
