<b>Auction</b>\n
3\D: Weak - as partner is a passed hand, opponents have game on - so get in the
bidding.\n
X: Takeout - the diamond spots are poor and the hearts good; you may be able to
bid 3NT on the next round.\n
4\S: 3\S would be non-forcing, so East jumps to game.\n
I do not think East-West would bid a slam on an uncontested action. It is even
harder when they lose a round of bidding.

<b>Play</b>\n
A contract of 6\S would be good. It usually makes unless South scores a ruff or
someone has \SJ-x-x-x-(x). The ruff could happen if North has \HA-x-x-x-x or
all the missing clubs. In fact sometimes you can make 12 tricks even if North
has \SJ-x-x-x via a trump coup.

When South shows out on the second spade, you do need a trump coup for 12
tricks. You will need North to hold 3+ hearts & 3+ clubs.

You need to use dummy's entries to ruff 2 diamonds and then have the lead in
dummy at trick 11, with \HK and \DQx in dummy, and \SQ10 and \CA in your hand.}

{<b>Commentary by Julian Pottage</b>

<b>Auction</b>\n
3\C: With 6 good \S, 17 HCP and excellent controls, West is heading for a slam.
7\S may be on if East has the right \H holding.\n
4NT: When East shows a minimum, West gives up on 7\S but wants to check key
cards.

<b>Play</b>\n
Against a suit slam you usually attack - but South had the chance to double 5\H
so will not have much in hearts. Also it sounds like dummy is balanced.
Therefore North will probably lead a club.

If dummy had one more entry, you could play for an elimination. You could cash
the \SA and ruff 3\D in hand. You would succeed if the \SK was singleton or you
endplayed North. 

On the actual layout there aren't enough entries for a full elimination, so you
take the trump finesse, starting with \S10. If that doesn't work, you can later
try the heart finesse.

On the actual layout, the \H finesse is for the overtrick.

If North led a \H, you could guarantee 12 tricks by laying down the \SA and
playing another \S. Since it is unlikely that North has 7 \H and a singleton \S
K, you would not do that at matchpoints.}

<b>Auction</b>\n
2NT: With 6 good \C, you can value the North hand as 20 points.\n
3\C: Responder can only envisage a slam if a fit is present.\n
3NT: I play 3NT to show 3\S and \<4\H. This caters for responding hands with
5\S and 4\H.

<b>Play</b>\n
After a heart lead, if every finesse was wrong, declarer cannot see 9 tricks.
Trying to knock out the \DA early seems logical.

West is likely to duck the first \D and then declarer has a rethink. 

With a \D trick made, 4 in \C, 3 in \H and the \SA would total 9. So switch to
\C, starting with the \CA. It is a guess whether to continue with the \CQ or
the \C10. If you guess right, you make an overtrick.}

2\S: East has so many losers that pass is an alternative.\n
3\D: South does have 4\H (suggesting a double) but the \D are much longer.\n
5\C: South is close to making a 4\S cue bid on the way to 5\C. A 3rd \C or the
\CQ would be a better holding.

<b>Play</b>\n
East will probably lead a spade (but might lead a \H instead if South cue bid
4\S).

Declarer trumps the spade lead, and plays \DAK to throw the other spade.
Declarer can afford to lose a trump (or a ruff) but not a \S as well.

Now declarer ruffs a \D to set up the suit, and plays \CAK and another club. By
knocking out the \CQ it will be possible to run the \D without interruption.}

<b>Auction</b>\n
1\D: East has a strong hand but 1\D is fine.\n
2\C: Few people play 3\C as strong these days.\n
2\S: Even if 2\C is not a game force for you, an opener's reverse creates a
game force.\n
3\D: By rebidding the \D East shows 6+ \D and 4 \S.\n
4\D: West's 'solid' \C look less solid facing 10+ cards in \D & \S. J-x is fine
for raising now that East has shown 6 \D.\n
5\H: 2 key cards (with \D as trumps).\n
7\D: As 5NT says you have all the key cards & the \D Q, West just bids 7 \D.
Even at matchpoints it would unwise to bid 7NT. A grand slam bid and made is
almost always a good score.

<b>Play</b>\n
South probably leads a traditional trump. 

Declarer draws trumps starting with \DJ to avoid blocking the suit.

Cashing the second top \C reveals the 4-1 split. A ruff then sets up the suit.

If \C are 5-0, you still have chances. If North is void in \C, you could
finesse in \S or play for a double squeeze. If South is void in \C, there is a
simple squeeze if South has the \S K and either the \H Q-10 or any 6 \H - or
you could take the \S finesse.

An alternative line is to play a \S to the ace at trick 2. Then ruff a \S at
trick 3, come to hand with the \H K and draw trumps. That line works if \C are
5-0 without the need for either a squeeze or taking the \S finesse. However,
you go may down if \S are 7-1.}

3NT: South employs Hamman's rule: if 3NT is an option, bid 3NT.\n
4\C: North has some slam interest, especially if a fit is present.\n
5\H: The raise to 5\H is a clear slam try in \H.\n
6\H: With 5 \H and good controls, South accepts the invitation.

<b>Play</b>\n
West will lead a \D. The lead and East's vulnerable 3\C opening indicate that
\C are 7-0.

Declarer should draw trumps, then cash a second diamond. The 8-1 \D split is a
surprise but worth noting.

When declarer plays on spades, the fall of two high \S from East would usually
suggest finessing the \S8 on the third round.

However, the confirmed 7-0 \C split gives declarer a complete count, which
means \S are 3-3.

If declarer could not tell whether West had 3\S or 4\S, it would still be wrong
to finesse the \S8. If East shows out on the 3rd \S, let West win the 4th
spade. A ruff and discard then gives you a trick.}

2NT: If 2NT shows 20-21 then North will be interested in a slam only if a fit

3\H: If you play 5-card Stayman, South's 3\H shows 5 \H - not what North wanted
to hear.

<b>Play</b>\n
Against 3NT West will lead a club, not a heart, when South has bid hearts.

Declarer can count 4 tricks in \S and 4 in \D so needs only 2 in \C to make 11
in all. After winning \C9 with \CK, declarer plays another club.

If you needed 3 tricks in \C then you would finesse because East is more likely
to hold 9-5 or 9-6 than 10-9.}

2\C: If you play 3\S as a splinter, I think East is too strong for that. If you

3NT: West has poor \D and values in both majors.

<b>Play</b>\n
North will lead a low heart. At no-trumps it is normal to lead low from Q-J
without the 10 or 9. I do not like leading from 4-card suits headed by the ace.

With the \SK protected, finessing South for the \CQ ensures 11 tricks and gives
the chance of 13. It's best to cross in diamonds and run \CJ.

If North led a \S at trick 1, declarer would (at teams or rubber bridge) simply
cash 10 tricks. At matchpoints you might be able to judge from the discards who
has the \CQ and risk a \C finesse.}
