1968.1cash third heartGAAS::BRAUCHERAnd nothing else mattersMon Jun 02 1997 10:2510
  Partner started H-Jx, so the third heart cashes, and I can choose
 then to continue with a fourth heart, killing the pitch and possibly
 promoting SJ, or shifting to a club.  I'm unable to construct a deal
 consistent with the bidding in which cashing the third heart is fatal.
 Hopefully, partner's discard will announce whether he holds the club
 ace.  Unless he tells me otherwise, I'm inclined to continue a fourth
 heart at trick 4.

1968.2Heart ruff?SUBSYS::SENGUPTAShekhar Sengupta DTN 237-6785Mon Jun 02 1997 13:149
    If partner has a Spade honor that promotes my SJ or a club trick, those
    won't go away. What can go away, however, is declarer's diamond loser
    on the HT. Therefore lead a low H to have partner ruff and deprive
    declarer of his D discard.
    
    I expect declarer to have:
    AKQxx-xxx-Jxx-AQ or AKQxxx-xxx-Jxx-A

1968.33rd H honBULMER::KABLESHKOVTue Jun 03 1997 10:468
    What does decl push to game on? Who's vul, anyway? Who's N-S?
    Seemingly they are. Then decl must have 6+ spades headed by
    AKQ and high C. Pard 3C seems preemptive, on 6-7 clubs. Hence decl
    likely has CA(x), and was trying for 3N. Cash 3rd H and watch 
    pard carding. If he has trump at all (let's hope 
    it's ST) he'll ditch his highest C, asking for H-ruff. Else
    he'll play small, and then you have no choice but C.
    Yes, BB, hardly possible for 3rd H to go wrong.
1968.4The (hard) answerROKKON::mko-ras-port-2.mko.dec.com::CohenWed Jun 04 1997 08:4973
It seems hard to even consider the winning defensive plan on this hand.

Here are all for hands:

		S 863
		H T976
		D AKT2
		C 96

S J54				S 9
H AKQ5				H J8
D 963				C QJ75
C 752				C KQT843

		S AKQT72
		H 432
		D 84
		C AJ

As a review
You are defending 4H after:	1S-P-2S-3C
				3H-P-4H-P
				4S
What do you do after cashing 2 hearts and finding out that partner
has a doubleton?

Got it now?
Answer after several blank lines.


















The answer is that you must switch to a club to break up the sequeeze against
your partner.

I held the South hand as the second hand in the first qualifying session against
another seeded pair. Against me they continued a low heart (surely it must be
better to cash HQ and play a 4th). When RHO lead back the KC and it didn't get
ruffed I was so excited I tabled my hand, not claiming, and said that the D2 was
the last trick after drawing 6 rounds of trump. Bad form, of course. The opponents
made me play 5 rounds of trump before they gave up. Notice that I can't claim after
4 rounds of hearts, but since the squeeze which looked like a double was really only
a single against RHO, I would make on that defense as well.

It seems to me that real careful analysis will get this one right. Declarers shape
is certainly 6 spades and 3 hearts. If declarer was 3-1 in the minors as someone
suggested, why didn't they make a "help suit" try in diamonds? I certainly would
have and would have accepted a counter try of 3H. If declarer is then 6-3-2-2
then you want to continue hearts if partner has the ST otherwise you need should
shift to a club. At matchpoints you might worry that declarer has the DQ and will
get to throw heart loses, but then why didn't declarer bid 3N over 3C. Same applies
to declarer having CAQ. I almost called 3N with my actual hand and, in fact, one of
the other better players did exactly that with on the same auction. Well, there are
4 small spades outstanding (including the ST) so partner is only 25% to have that
card.

Ergo-play a club.

Is my analysis too much based on the cards that I had rather than bridge data?
1968.5Strange...BULMER::KABLESHKOVThu Jun 05 1997 13:2311
    Now we learn (what was only suspected) that decl was vul. Then to 
    me the 3H makes sense if S was AKQxxx-xxx-Q(J/x)x-A. With reds wide 
    open, in MP, a vul S pushes to game?!? I also wonder what's the point 
    of asking 3H if (a QT-stronger than expected) N will by-pass the only 
    making game (3N)?
    
    E should have known better than peter-out in H. He could see the
    D-C sqz looming at tr 1, and play H8 first (still smelling of
    of H-doubleton; else J then 8 strongly indicates a ruff-wish). 
    After tr 2, W would have no problem solving the riddle.
                                       
1968.6Some problems are too hard...GAAS::BRAUCHERAnd nothing else mattersFri Jun 06 1997 10:0910
  OK, I admit I didn't see I was rectifying the count for the squeeze.

  I think it's impossible.  I have to lead out HAK - we could have the
 first four tricks if pard shows out.  Now, once pard high-lows, I could
 cause a disaster by switching.  Suppose declarer had AKQxxx xxx Qx Kx ?
 Now ANY other defense works, trump promotion, etc.  And if declarer had
 AKQ10xx xxx Jxx A, I've blown my last chance to kill the pitch.
