Yes, 4NT is cold.  However, after unfortunate judgment in the auction, you
declare 5\C.

West leads a fourth-best \H5, you insert the jack, and RHO wins the \HQ.  East
shifts to the \DK.  Plan the play.}

{

Playing in the Warwick, RI, Regional A/B/C pairs, you pick up the East
powerhouse.  North opens the bidding, you double for takeout, and partner
responds 2\C.  What next?

After making a takeout double, a cue bid of the enemy suit shows a good hand
with <i>doubt as to strain</i>.  That's exactly what you have -- you don't know
whether to play in no trump, spades, or clubs -- let alone game or part score.

When partner has bid a major suit, cue bidder will usually have exactly three
card support for that suit.  In a minor suit, 3NT is always an option, even
with a good fit in the minor.

The cue bid works wonders.  Although 3NT can be set on the lead of the \HA, few
players would try that with North's hand.  On the normal lead of a low heart,
partner easily rakes in four spades (bad split), three clubs, a diamond and a
heart.  The reasonable four spade contract should be set.

With a weaker heart holding, West might try 2\S, having already denied four
cards in the suit.  The deal would then be played in spades.  Holding \SJ3 
\H9842  \DT42  \CQ763, West would rebid 3\C, expecting 3-card support -- have
to bid something.  }

Partner leads the \D4 against South's 3NT.  Plan the defense as West.

Obviously, you rise with the \DA.  The issue is what you play next.  Do you
have your answer ready?

<i>The Complete Book of BOLS Bridge Tips</i>, edited by Sally Brock, is one of the
great bridge books of all time.  The articles in this book were originally
submitted by the world's top players to a competition sponsored by BOLS Royal
Distilleries from 1974 thru 1996.

"Tip for the pip" by Jose le Dentu (France) covers this case:  what to lead
back, when partner leads from length at a no trump contract, and a singleton
appears in dummy.  Your normal carding agreements should no longer apply.  If
you have four (or three) cards, return your highest card, to make it difficult
for declarer to duck into partner's hand.  Only return a low card if you
started with <i>five</i>.  That tells partner to unblock, so as to be able to run the
suit.

If you return the \D7 (even though of no useful strength on this deal), partner
will take declarer's \DJ with the \DQ and shift, setting the contract.  If you
return the \D3, partner will win the \DQ and unblock the \D10 -- disaster.}

{6. Two keycards with the \HQ or extra trump length.\n
7. Do you have third round control of diamonds?}
[Result ""]
{

Two aces will be enough for South to bid a small slam.  Should North show extra
length in trumps, knowing this may turn into a grand slam?

The answer is a resounding NO.  Don't bid speculative grand slams!  This can be
demonstrated using Kit Woolsey's "cost of being wrong" analysis, from
<i>Matchpoints</i> (© 1982, updated recently).

Suppose half the field stops in game, and half bid a small slam, all contracts
making.  Those who bid the slam beat the gamers and tie the slammers, for a 75%
score.  If we stop in six and are wrong, the cost is 25%.  If we bid seven and
are wrong, we get 0%, for a cost of 75%.  If the grand is 75%, then the
expected result is 75% * 100% + 25% * 0% = 75%.  Plan to bid a grand slam only
if it is 75% or better.

On the actual deal, having led a trump to the \HA and a trump back, playing the
\HK is 52%, and finessing is 48% -- on good play, the slam is down.  The full
chance of bringing in the trumps is 58%, as the \HQ could be singleton; worse
without the \H9. 

In our section, 7 of 12 pairs played game, not having the 3\S slam try in their
bag; 2 x 6\H+0 (64%), 1 x 6\H+1 for a 90% cost of being wrong.

I chose the obvious line:  won the diamond and led the \H3.  If East had played
the \HA, all set.  When East played the \H10, I ruffed high, cashed one trump,
two spades, and ruffed a spade high.  Trump to the \C10; when clubs failed, I
was one down.

The line that works is to win the first diamond and rattle off trumps,
achieving this position:}

On the penultimate trump, East is in trouble.  A spade discard immediately
establishes the \S8.  After a heart discard, a spade to dummy and a heart ruff
establishes the \HK.  So, East discards his diamond exit.  Now three rounds of
spades forces East to lead away from his \HA.}
