A perfect cue bid.
Neither side vulnerable.  
North deals.

	  Opening Lead: KD     
     This hand was played at a local duplicate bridge game.  I
held the South cards and Mort Pierce of Chagrin Falls sat North. 
After East made a weak two diamond opening bid, I had no real
choice but to compete with a take out double.  
     Pierce's three diamond call was beautiful and it is a bid
that is often overlooked.  In one bid he was able to tell me that
he had a near opening hand with at least four cards in each major
suit.  My four spade bid ended the auction.
     West led the king of diamonds which I trumped low.  A club
to the jack held and I trumped another diamond.  A club to the
ace was the entry to trump the last diamond.  The ace of spades
was cashed and a heart was led to the king.  The king of spades
was next and when both defenders followed ten tricks was
guaranteed.  Now was the time to think about overtricks.
     I called for a small heart from dummy and the queen appeared
on my right.  The ace won the trick and a small club was led. 
West played the king and I trumped low.  East won the trick with
the queen of spades but that was all the defense could come up
with.  Making six was an excellent matchpoint result.  Many pairs
missed bidding the game - but Pierce's cue bid made it an easy call.
