   There is a class of interesting problems involving the construction of
a deal (i.e. a distribution of the 52 cards) to satisfy certain properties.
One of the most fascinating is to construct deals in which N-S can make a
grand slam in any suit, but fare poorly in no trump.

   As an example I give a deal below in which N-S can make 13 tricks with
any suit as trump but only 11 in no trump.  There are many solutions but
the one I give is perhaps the most elegant (certainly the most symmetrical).
Can anyone construct a deal in which N-S can take only 10 tricks in NT?

   Another possible extension would be to hands where N-S can make a small
slam in any trump suit.  Although I have not worked on this, it seems likely
that they could be made to do very poorly in NT.

   P.S. If you are interested then I urge you to work on the problem before
looking at the solution below.

N-S can make 7S, 7H, 7D, or 7C, but only 5 NT.
