I did not read any of the rebel-beta-tester reviews so far.
maybe i have to do today to understand what you say.
i wonder if the above thing you say is an example
and there has really somebody written about this function without you
beeing satisfied about.

IMO a program needs to have multiple-variation mode like almost
all chessbase engines support. this way you can find out
about the position very very early. good moves are normally
within the first 5 branches of the move order, so
looking the first branches of a chess program up to a certain
depth gives you a clear image which branches are worth analysing
and which are completely senseless.

further i don't like chess programs with asymmetric score.
when it analyses a position, and says +0.13 for white in ply/search 16
and i input the first move of its main line, and it says suddenly
+1.09 for black i wonder how you want to use this engine for analysis.

also asymmetric search is shit (genius comes to my mind),
you let it consider very very long. and one ply later it comes with
completely different main-lines !

ah ! i have to read them.
i don't remember exactly WHO was in the beta-test crew, since some
of them used anon names, or strange names i never heard.

maybe these people are not professional writers/testers or do not
have the time to write a good review.
imo a good review needs much time.

when i wrote a review in those old days of dedicated machines,
the first stage was the collecting data and impression time.
it took nearly almost 1 month.
then an idea came out of the data. i tried to follow the idea and tested
some special positions that should decline or prove the idea.
than another month to write the review.

meanwhile, at a weekend, the guy called B.Schne...r
came, quoted 89% of the handbook and presented NO single chess move.
so i needed at least 2 month to write something about the machine,
and he came and made his "best articles" at a week-end.

i stopped competing this senseless contest.
if the magazine is not interested in good reviews, but instead is interested
in shallow stuff, they shall do it.

yes. your ideas come very close to my own.
