3NT or 4♥? – Advanced Stayman in Doubt Board 5 from Friday 25th Nov

Table A: (1) What did you bid with this North hand A in this week’s quiz? This hand is totally flat
and some will simply forget Stayman and bid 3NT directly. I disagree with this concept
(because partner may not be totally flat) and will only do this with a stronger hand where
I think there are eleven tricks in either contract.
There is, however, a way to find out if partner is also completely flat…
Table B: (1) Stayman, which is what I bid whether playing SID (or ASID) or not.
(2) Now that the ♥ fit is uncovered, North wants to know more about partner’s shape
(in particular if he is exactly 3433). 3♦ here is Advanced Stayman In Doubt (ASID)
and asks partner to clarify his shape.
(3) 3433 and minimum when playing ASID.
(4) with known total duplication in shape, North opts for 3NT.
And what happened? 3NT and 4♥ both make 10 tricks.
The bottom lines:

You are West, declarer in 7♥. North leads the ♣K, plan the play.

The grand slam seems to depend on a 3-3 break in ♠’s (unlikely) or a singleton ♦K (also unlikely).
Do you see another, realistic, chance of making the contract?
You win the ♣A and pull trumps in one round. You then cash two ♠’s and confirm that that suit is
not breaking, is there still a chance?
Yes, if South has the ♦K to go with his long ♠’s you can indeed make 13 tricks – if you play carefully.
The proper technique is to cash the ♦A,
not relevant deliberately setting up South’s ♦K, then run
trumps. At trick eleven, this is the position:
♠ 6 N ♠ Q4
♥ 4 W E ♥ - When West plays the last ♥ and pitches a ♦ from
♦ Q S ♦ 6 dummy, South is forced to discard and give
♣ - ♣ - declarer his 13th trick.
♠ J10
♥ - West’s early play of the ♦A is known as the
♦ K Vienna Coup.
♣ -
And what happened at the Pattaya bridge club? Only the one pair bid the grand, and very well done
Jeremy who played it exactly as in the article. Most of the rest were in 6♥ but nobody else made 13 tricks.

You must assume that the red suits will be cooperative (♥’s 3-2 and ♦’s 2-2). Can you take
advantage of these lucky breaks?
Even assuming that you are lucky in the red suits, it will not work to play the ♦A and another ♦.
The defender’s will play a 2nd round of ♠’s, shortening you to three trumps. When you later duck
a round of ♣’s a third round of ♠’s will shorten you further. When you then ruff a ♠ in dummy,
each hand will have only two trumps.
The solution is to trump the opening lead and play low ♦’s from both hands at trick two.
The defenders will force you again in ♠’s, but when you duck a ♣, you are in control.
If they play a third round of ♠’s, you ruff, cash the ♥KQ, play a ♦ to dummy’s ♦A and pull the
last trump, pitching a ♣ from hand. The fifth ♦ takes care of the other losing ♣.
If the defenders play any suit other than ♠’s at trick five, you can ruff a ♣ in dummy, pull trumps
and run the ♦’s for eleven tricks.
Bidding Quiz Answers
Hand A: 2♣, Stayman. You may be completely flat but partner may not be! Actually, there is
a way to find out if partner is also exactly 3433 after 1NT - 2♣ - 2♥ (see article).
Hand B: 3♠, this cue bid is Stayman promising game values and four ♥’s. If playing Lebensohl
it also denies a ♠ stop (what a great convention!). A 3♥ bid here promises five ♥’s.
