Whalen is ex-military (ret.) and by his own accounts a
succesful player (I will not attempt to refute).

His writing style is 'folksy' and full of quaint sayings
that have some applicability, but are best "taken with a
grain of salt."

The book is not in front of me (in a different state) but
I recall a couple of strategic errors as well, at least as
written. Many strategies are applicable in specific
situations, his situations were not well defined and therefore his advice somewhat dangerous.

An experienced player capable of getting thru the
'minefield' can pick up some useful things. This
may be most true with the psychology aspects.

So the book is not without value, just don't
approach it like a 2+2 book where everything can
be assumed to be accurate (even if the writing may
be poor).
