Hello Heinz,

I have already stated to Harry and others (as you're aware)that his small book
and test suite are the fairest I've used to date.

I've also stated that there is no book, either commercial or otherwise, that
does not have dubious lines.
Others may or may not agree with my thoughts on those positions posted. It would
be good to get other opinions.

I stand by my assertion that ideally, the evaluation for each side coming out of
the opening should be no higher than 0.50
Again it would be good to get some opinions on this also.

My intent is not to enter into an argument with you or to offend Harry, so I
will make no further comments on this.
I do look forward to reading the opinion of others though.

Regards, Graham.
