发帖数: 524 | 1 In a knockout, you start the last set down by 46 IMPs. Now 11 board done, 5
to go and it seems you have picked up 20 something IMPs so far.
vulnerable, you pick up:
S AKTxx H Kxx D AQ C AJx
Open 1C (strong), partner 1N(balanced 8-10 HCP), you rebid natural 2S,
partner 2N.
This hand is an Ace more than a minimum (17P+ balanced) and you decide to
give another push: 3C, partner raises to 4C.
Partner is likely to have 5 clubs, because otherwise he may rather bid 3 new
suit to imply club fit than raising to 4.
Seems you are on the right track: 4H ask key card, 4S shows 1, 4N ask trump
Q, 5C says no. The bidding has been:
1C 1N
2S 2N
3C 4C
4H 4S
4N 5C
?
Do you bid slam now? why or why not? | b***y

发帖数: 2804 | 4 Still not sure why 3C, which distorts the hand.
Normally you shouldn't even try for slam, just bid 3NT. Now you need a swing
, so maybe 6C is worthwhile. If partner just has DK and CK, you have a fair
chance. Partner should have more than that. Good luck.

发帖数: 20570 | 5 The bidding is strange. After 2S, with 2-3-3-5, the natural bid is 3C, not
2NT.

发帖数: 642 | 7 So the reason for not bidding 3C is likely due to weak suit. Anyway 3NT is
an easy make. If you like to create swing, the better chance seems to be 6NT
. For example, if pd holds
Qx
Axx
Kxx
T9xxx
It works when either S or C suit splits friendly.

发帖数: 2804 | 8 This hand requires C splits friendly. In that case 6C will make too. Spades
are irrelevant: if you can take 4 clubs, you don't need spades split; if you
have to lose 2 clubs, then spades 3-3 doesn't help.
But on some other hands you may need to establish spade tricks. For example:
xx Qxx Kxx Kxxxx, 6NT has almost no chance, while 6C may roll home even if
spade splits 4-2.

发帖数: 2804 | 9 Yes that's the fear. Maybe partner just has 4 good clubs, like KQTx. That's
why 3C is bad. No need to bid 3-card suit and risk partner raising with 4.
Usually when one manufactures a bid like this, there needs to be a good
reason. Here 3C doesn't show extra value as this hand has, but it does
distort shape, I see no justification.

发帖数: 642 | 10 My guess was based on the assumption that pd does have 5 clubs. Then it is
likely weak, which he thinks it is not worthy to introduce. If this is true,
the chance he holds SQ increases. In the hand I gave, if LHO holds stiff CQ
or CK, where declarer may have only two club tricks, 6NT still has chance
relying on spades.

发帖数: 2804 | 11 Then you specifically need partner to have SQ and CT9, and LHO having stiff
club honor. If he doesn't have C9, 6NT is no better than 6C. There will be
far more hands that 6NT is inferior.

发帖数: 20570 | 12 With SQx, partner might bid 3S to show that specific hand type. Qx AQx Jxx
T9xxx, it looks like a 3S bid to me (or 3H).
4C is probably more like xx Axx KJx xxxxx
6C is a contract that always has some chances to make and the chances are
usually bad.I guess the average chance to make 6C is about 20% facing a bad
C suit, which is likely the case. Even facing CKxxxx, the chance can still
be under 40%.
6NT can be wrong sided even if partner holds SQ, like SQx HAQx Dxxx CT9xxx.
So, it's probably wiser to just stop at 5C which can be high already.5C can
be good some times. For example, opps may lead H against 3NT and you may
have problems to develop the 9th trick, when S is 4-2 and C is 3-2 in the
first lay out. Therefore, pass can still be a winning bid in this hand and
the chance might not be very small.
5 boards to go, you still have chances to catch up.
true,

发帖数: 524 | 13 Good analysis.
Stretch a 20% slam is a little over the top, even when you need the swing.
But if partner's club was KTxxx, one had to assume he could get it right
anyway. I bid 6C, Unfortunately, partner had: S Jx H Jx D Kxxx C Kxxxx, no
club 10 or 9. with CQ offside, no play, down 1, good for a push.
At the other table, 3NT played by the strong hand, after heart lead, how to
make 9 tricks was not so obvious...

发帖数: 2804 | 14 Why didn't partner bid 3C? This hand shows that a swing doesn't have to be
created by stretching to an unlikely slam, it could be done with bidding a
game of different strain. Another example is to bid 3NT when you expect the
other table is on 4M with 4-4 fit. But to do this, you often need to have
correct information, it's better to bid honestly.
