This North-South are playing transfers and Blackwood.\n
In this case the 2\H transfer followed by 4NT Blackwood shows slam interest in
spades.

North’s 5\H shows two Aces; The partnership has all four aces. South can see a
possible king trick for the defence so bids 6\S.}
[Result ""]
{

East’s best opening lead is \CQ.

Declarer wins the trick with \CK, cashes \HAK and ruffs \H2 with dummy’s \SK.

Draw the trumps. It does no harm to try the diamond finesse now. It fails but
the remaining tricks are all won to make the contract.}

minimum of 29 HCPs, so a slam may be possible.

The 4NT and 5NT Blackwood sequences reveal that East has three aces and zero
kings. There is a king missing so West settles for 6\S.}

Win South’s \CQ opening lead with dummy’s \CK. Cash \HA and play a second round

Get back to hand and ruff the last heart with \SK.

With a great diamond suit and only four losers, North realises that a NT slam
could be on.

4\C Gerber asks about aces: 4\S shows two aces.

5\C Gerber asks about kings: 5\H shows one king.

There is a king missing, so North settles for 6NT.}

There are 12 top tricks but there might be 13 if the club finesse is
successful. Run the diamonds and then try the club finesse while there is still
cover in both hearts and spades.

{

With an eight-card fit in spades and four losers, East is interested in a spade
slam.

The next step depends on partnership agreed methods. If playing transfers, East
will transfer to spades and use Blackwood.

Without transfers, a bid of 4\C Gerber asking for Aces finds the partnership
with all four. 5\C finds two missing Kings. The club suit is covered, but there
is likely to be a heart loser so settle for 6\S.}
[Result ""]
{

12 tricks can be made by cashing \HA, then lead \H7 towards \HQJ. Two diamonds
can now be discarded on \HQJ avoiding the losing diamond finesse.

South’s 2NT shows a balanced 20-22 HCPs. North has a balanced 11 HCPs so the
partnership has a combined total of 31-33 HCPs.

North’s 4NT is a quantitative bid inviting 6NT if opener has a maximum 22 HCPs,
otherwise pass.}

There are 10 top tricks: 4 spades, 2 hearts, 4 clubs.

The other two tricks must come from diamonds, so declarer’s first task is to
drive out \DA. 

When that has been done the remaining tricks can be claimed.

After an opening 1\S by North, East starts with a double to ensure the bidding
remains open for one round.

The 2\D response to the double is difficult to read because it is a forced bid.

With such a strong hand, total control of spades and no action from South, East
bids the diamond game.

West has two tricks more than East can count on, so raises to the small slam on
the probability that it makes and the slam bonus!}

From the bidding North must hold \DA, so use \HAK as two entries to dummy to
lead small diamonds towards \DKQ to ensure that \DA is the only trick to be
lost.}

After a weak 2\S by East, South starts with a double to ensure the bidding

West passes and North responds 3\D, so South rebids 4NT Blackwood to find that
partner has the missing \HA. South continues 5NT Blackwood to find partner
either \HK or \SK.

South counts tricks: 6 clubs, 4 diamonds, plus 2 aces and one king from hearts
and spades for a total of 13, so bids 7NT.}
