I read the book -- I FOUGHT THE LAW OF TOTAL TRICKS -- and found the
first half in which hey demolish Total Tricks to be well considered and
useful. However, the second half, which you refer to, has several flaws:
1: If it often very difficult to calculate the number of points held by
either side in a competitive auction.
2: In a non-competitive auction it is often difficult to figure out
exactly how many cards partner has in a suit unless you are playing
splinters; at which point, I find that I am usually sufficiently adept
at visualizing hands to start cue-bidding figure out if slam is a
reasonable idea.
3: Even in cases in which you can make reasonable assumotions --
partner opens a major, you play 5-card majors, so he can be placed with
a doubleton -- mirror hands can provide major flaws in this evaluation
-- as shown in the example above.
4: The issue of whether a card is a working honor or not. Stiff King
may be a working honor opposite QJTx but not Jxxx
In sum, I find that this method is not particularly helpful once you
have advanced past the point of relying solely on modified point count
in evaluating the hand and have learned to place sample hands that match
the bidding in your mind. I suppose some people would consider that an
advanced stage. I consider it the beginning of intermediate. It is, in
sum, a fine evaluation method to use if you are playing Churchill, a
system that does not usually work as well as it should, even in the
hands of its originator, alas.
