{<b>Bidding</b>

Several auctions are possible, depending on what South bids over 1\D. After
West shows hearts, East should show a good hand with support. Then after some
cue-bids the partnership will probably bid slam. Because the diamonds are not
solid, it is better to play in hearts, not in notrumps.

<b>Play</b>

After the spade lead, declarer should draw two rounds of trumps. You should
keep the entries flexible, for example cashing the 10 and 9, so that you have
\HAQJ opposite \HK.\n
If trumps are 4-1, you need diamonds to be 3-3, so draw two more trumps and try
to cash the diamonds.\n
If trumps are 3-2, play \DAK and ruff a \D high. Draw the last trump ending in
dummy, and discard the \S85 on dummy's two \D winners.}

{<b>Bidding</b>\n
\DQJ are not worth much opposite a singleton. But diamond length is good, and
\HK3 is a fitting honour. When South cooperates, North can bid slam.

<b>Opening lead</b>\n
No lead is bad. A club or a heart could set up a trick. A spade could help to
prevent diamond ruffs.

<b>Play</b>\n
Declarer should play to ruff two diamonds, then draw trumps, then throw the
last diamond on \HQ .

<b>Bidding</b>\n
You might reach either 6\D or 6NT.\n
6\D is slightly better, because if you can lose only one diamond trick you can
trump a heart for your 12th trick. 6NT might go down if clubs are 4-1 and \DQ
is in North.

<b>Play in 6\D</b>\n
They may ruff a club at trick one. After that, you have to get trumps right.
Because North has 5 clubs, it is more likely that South has \DQ than North, so
you should finesse.

If North leads \HQ, so there is no club ruff, you just need to play trumps for
one loser, and arrange to ruff a heart. Simplest is <b>\D</b>A, <b>\D</b> to
the jack, <b>\D</b>K, then take the ruff.

<b>Play in 6NT</b>\n
If you play in 6NT you will probably get \HQ lead. You start with 10 top
tricks. If clubs are 3-2, you have two more.

Win the opening lead and cash a top club. With clubs 5-0, you know that you
need 4 diamond tricks. Cash \DA, in case something happens. North and South
both play small diamonds.

Now you plan to finesse in diamonds, but why not cash the spade winners and \HK
first? Again, something may happen.

When you play the spades, something does happen: North follows to all of them.
Now you know she has 8 cards in spades and clubs, as well as probably \HQJ10.

When you play \HK, does she play \H6? If she does, then she probably started
with \HQJ106. With \HQJ6 she would probably not risk a heart lead. So, she is
3=4=1=5. Cross to \CK and play a diamond to <b>\D</b>9. Finally cross back to
\CQ and finesse \DQ.

Did North play \H10 under \HK? That's a good play, to make you think she might
have \HQJ10 and \DQx. Maybe you should still get diamonds right. North could be
4=4=1=4, 3=4=1=5, or 3=3=2=5, and against two of those shapes it is right to
finesse \D9.}

{Declarer has 11 top tricks. There are several chances for a 12th trick -
either minor could be 3-3, or the spade finesse could work.

But there is an extra chance. If East has four cards in one of the minors, it
is very likely that you can endplay her.

Cash \DAK and \CAK, then the heart winners, and finally \DQ and \CA. When East
has four diamonds (and not four clubs), simply play the last diamond, throwing
your spade, and East is endplayed.

There was an alternative line - try the spade finesse early, then if it loses,
try to squeeze East in clubs and diamonds. This needs East to have 4-4 in the
minors. This is less likely than finding East with only one of the minors.}

{<b>Bidding</b>\n
If North bids Keycard and hears of three keycards, she shoudl now bid 5NT to
confirm that all the keycards are held. With a lot of extras, South bids a
grand slam. 

<b>Play</b>\n
If you bid 7NT, that's unlucky. This time it is better to be in a suit.

In 7\D it looks as if you have 13 top winners: \SAK, \HAKQ, \DAK and 6 trumps,
unless trumps are 5-0.

After winning the lead, you play a diamond to \DK. East discards, so West does
have all 5 trumps.

You still have very good chances to make the contract, because you have \DAQJ7
over West's \DT864. Start by playing dummy's \D9. West must cover with \DT, so
you win with \DJ in hand.

Dummy has no more trumps for a further diamond finesse, but you may be able to
finesse West's trumps by playing spades through her. For this to work, you have
to reduce your trumps to the same length as West, and also have spade winners
in dummy to lead through her.

To achieve this, play a spade to \SA and ruff a spade.

Stop for one moment to count your winners. You will need enough spade winners
to throw all the non-trumps from your hand. It's OK - there are 5 spade
winners, just enough.

Go back to dummy with \HQ and play \SK, then the rest of the spade suit. If
West ruffs, you can overruff, draw the rest of the trumps and enter dummy with
\HA to cash the rest of the spades.

West does best to discard, but you throw the losing club from your hand,
followed by your hearts and clubs. On the last round of spades you throw your
last side-suit card.

Your last 3 cards are \DAQ7 over West's \D864. Play any card from dummy and
overruff West's trump.}

After North wins the first trick with \HA you have eleven top winners. You will
be able to make your twelfth in diamonds unless South is void.

At trick 2 North switches to a club. You win in dummy with \CQ, keeping the
entries flexible. When you play a diamond to the ace, South discards.

You can't afford to lose a diamond trick, so you will need another trick from
spades. The obvious chance is to finesse \S10, playing South for \SJ. At this
point, the spade finesse is more that a 50% chance, as North has 4 diamonds and
South has zero.

Another possibility is to play North for 4 spades. Then you can squeeze her in
spades and diamonds. At the moment this is worse than 50%, again because South
has zero diamonds, so more room for spades.

Before making a decision, you should cash the hearts and clubs, to find out
more about the distribution. Make sure that the last winner you take is in the
East hand - that will mean that you are in the right place to take the spade
finesse, with \DQ as an entry to cash the last spade. (Remember what you did in
clubs at trick 2!)

When you cash the hearts and clubs, you learn that hearts were 7-1 and both
players had at least 3 clubs. Now you know that South is 3=7=0=3. North has
already thrown a spade on one of the heart and club winners, so you know that
your spades are winners by playing them from the top.}

{Lead: \CQ

You have 10 top winners. You'll always be able to establish an extra trick in
diamonds, perhaps two if the suit is favourably distributed. If not, you can
still make twelve tricks if spades are 3-3.

You don't want to set up a spade winner for the opponents, so you must play on
diamonds first. If diamonds are 3-3, anything will work, so think about the 4-2
breaks. There is one one 4-2 break where you can set up the suit - \DKx with
South.

Cross to dummy in hearts and lead \D2. South plays low and you win with \DQ.
Now play another diamond back and duck it, in case South has \DKx. If diamonds
are 3-3, you will still be able to cash the suit.

East wins with \D9 and plays back a club. Win that, cross to dummy in hearts
and try \DA, discarding your losing club. North discards on this trick, so your
diamonds are not winners.

It now looks as if you need a 3-3 spade break, but it would be a mistake to try
for this immediately. Cash your remaining hearts first. In fact, South has the
spade guard as well as the diamond, and she is squeezed on the last heart.}
