Preposterous Contracts!
« on: July 21, 2017, 09:08:21 PM »
Sometimes, even with OCP, you hit a sequence which might be ambiguous with a significant affect on the subsequent bidding. Imagine you are South (North was Eszter)


South
 !S AK
 !H Q
 !D KQ987643
 !C Q9


After some reflection you decide on a 1 !D Opening rather than 1 !C (and yes, I did give 1 !C some serious thought) and with no opposition bidding, the bidding proceeds


1 !D - 1 !H
3 !D - 4 !C (1)
4 !D (2) - 5 !D
??

(1) Does Partner think this is Beta? It is ambiguous, but I think it ought to be natural rather than Beta, hence my bid of 4 !D .
(2) Does Partner think this is showing 0-2 Controls or just saying I have a huge Diamond suit and no support for Hearts or Clubs? Is their subsequent 5 !D a sign-off, disappointed with my apparent lack of controls?

I tanked for quite a while while I considered my options here. In the end I decided (especially given that Eszter often tends to be in the wimpish side of aggressive) that I would rather be hung for going off in 6 than playing a cold 6 in a mere game, and bid 6 !D .

West (my hero) led the 2 !D and Eszter put down

North
 !S 93
 !H AK652
 !D 10
 !C K7532

South
 !S AK
 !H Q
 !D KQ987643
 !C Q9

East won the Ace of Diamonds and returned the Jack of Spades. I won, and cashed 2 more Diamonds, discarding 2 small Clubs from Dummy, West discarding a Spade and a Club. Now what?

Yes, you could just concede a Club to West's Ace [it's fairly clear they probably have that, because if East had had it, it might have been impossible for them to resist (a) Doubling and (b) trying to cash the A !C at trick 2]. You can see that with East having started with !D AJx, unless you were prepared  to run the 10 !D on the first round of the suit, even 5 !D is normally not going to be making, so you're only going -1 in 6 !D , when 5 !D -1 is probably the "normal" result. I decided to play my luck, though:

If West had 5-card Hearts and the Ace of Clubs, I can squeeze him out of his Heart trick. Also, the fact that Opps don't know I only have 2 Spades might put additional pressure on them.

I therefore  cashed the King of Spades and then ran all of my Diamonds, throwing 2 Hearts from Dummy and then all of Dummy's remaining Clubs. Opps both discarded 2 Hearts on the first 4 of those 5 Diamonds, and, amazingly, both discarded Hearts on the last Diamond, which meant that 6 of the 7 outstanding Hearts had now been chucked. I was now down to !H AK6 opposite !H Q, !C Q9, and took the last 3 tricks in Dummy for 15 IMPs.

6 Pairs were going off in 5 !D , and almost all of the rest were in making Diamond part-scores. One Pair had made 5 !D on the lead of the 2 !D by West but that was the only other pair making a game, let alone a slam.

Lucky? Yes, insanely lucky, but...

After trick 2, you might as well play as I did. If the worst comes to the worst and Opps keep all of their Hearts, one of your Club losers will disappear on the  K !H so you will still come to the same 11 tricks that the opening lead has gifted you. You might as well play for a mistake from Opps. My possible squeeze position never materialised, but the secondary position did, in that West felt he had to keep hold of the Q !S and A10 !C , and East felt he had to hand onto the 108 !S , which meant that neither of them could hold onto 3 Hearts and were presumably hoping that I was void in Hearts and had no hope of reaching Dummy's AK6.

Good lesson on not giving up. Also, hope you go to church twice tomorrow - someone is certainly looking over you.

I would take 4 !C as NOT being a High Beta with the reasoning that if Responder had a slammish hand they would be going through either an Alpha sequence [with a strong slammish hand and a 5-card suit] or a 1 !D-2NT sequence [with a strong balanced hand].

Also, the only times I have seen High Beta in a natural sequence is after trump agreement has occurred or been implied. I do believe one 1NT-4 !C sequence came up in one of the past practice sessions. So that might be another situation where 4 !C is High Beta. But none of that appears to be the case after 1 !D-1 !H-3 !D. So I am going with 4 !C as NOT being a High Beta.

After seeing Responder's actual hand, it is obvious that 4 !C was not meant as High Beta; but I can understand many new practitioners as seeing it as ambiguous.

Before parting, I have to admit I do not know what I would have done holding Responder's cards after 1 !D-1 !H-3 !D. I guess rather than bidding 4 !C [the 4 !C bid must be assuming the 93 holding in  !S is too scary for 3NT], I would bid 3NT - even with only 93 in  !S under the assumption Opener has 14-15 HCP so some of those HCP must be in Spades. Of course, there is no certainty there so I could end up with egg on my face. I guess Pass is another possibility. What would others bid sitting in Responder's seat?

You're absolutely right, John. It isn't really ambiguous, for the reasons you outlined above, but it is potentially ambiguous (because the system doesn't actually define what 4 !C is here), which gives rise to the worry that Partner might intend it as Beta (you have, after all, shown a maximum hand with long strong Diamonds), which in turn means they might have misinterpreted your subsequent 4 !D bid.
