My hand:

♠ J
♥ Q 10 x
♦ K J x
♣ A K Q x x x

The bidding (I was South):

S------W------N------E
1♣ - (P) - 1♠ - (P)
3NT - (P) - 6NT - (Dbl.)
P - (P) - P

The opening lead is a low ♦, and this dummy appears:

♠ A Q x x x
♥ K x x x
♦ A
♣ J x x

So, how do you play 6NT?

(Thirty-one IMPs are on the line.)

TWO ♦ Aces

Fixed.

(But if I'd gone down with 2 diamond aces, I'd be even angrier with myself.)

[TWO4BRIDGE]

I can count 12 tricks if 2 finesses work:
for the ♥J and ♠K ....

2s, 2h, 2d, 6c

RHO has ♠K (guarded) and ♥ A J x x

[CSGibson]

given that righty is known to have the ♠K and the ♥ ace for the double, I'd probably also play him for the ♥ jack, which, if he has it and I can read the position at the end, I am cold to make.

Low ♥ to the T, club up to the J, low heart to the Q. Now running 5 clubs pitching 3 spades from dummy. Righty has to come down to 4 cards, the K of spades, the ace of hearts, and two others. If he has 4 hearts and the Q of diamonds, he is forced specifically to come down to K Ax Q, and I'm making an overtrick. Otherwise I have a guess in the end position.

Righty will also have something to say about Lightner doubles, I expect.

It turns out that LHO has the ♦Q; think about what happens when you cash the ♦K.

(I was a moron: i didn't finesse the ♥10.)

There is no guess, you come down to (spots and W hand irrelevant)

---

When you lead the K♦ and pitch a heart, E can pitch a heart and be thrown in with the A to lead away from K♠, or pitch a spade and have his K dropped. Bog standard strip squeeze.

There's no guess if RHO follows to the second heart with a low one, but if he plays the jack (which he should) you have a problem.

Exactly!

(I didn't know what it was called, but I knew that it was cool.)

Good analysis.

(Would you have finessed the ♥10?)

Ps - how do you get that diagram?

I think LHO will often play a true count card on the first heart here, partner might want to know if declarer had Q10 bare or Q10x. He might be more likely to do this if he didn't know you had a lot of clubs, I really dislike the 3N bid, how are you going to enjoy 3N opposite partner's usual AJxxx, Jxx, xxxx, x ? We'd have started 1♣-1♠-1N (15-bad 19) and it would not have been so obvious.

Why is this in the expert forum? You are playing with a beginner against beginners, and the play problem is intermediate-advanced level.

No, neither am I impressed by the analysis.

East is marked with ♥A and the ♠K and from the opening lead with the ♦Q
The one card he need not have is the ♥J. If he does he will come under pressure anyway.
Just run clubs.
In the six card ending East is very likely to come down to

---

where East second heart could be the jack. You now lead a heart to the king.
To create a problem for declarer East must returns a low heart. Now you must take a decision whether East is good enough to have come down instead precisely to

---

If yes, finesse now. If no (true for most defenders) put up the ♥Q
Bingo, if West had originally ♥Jx (or ♥J singleton) or discarded some hearts.
If West originally had the ♥J and at least 3 hearts precise defense will beat me.
Against most defenders in my experience this is the exception rather than the rule.

Rainer, he doesn't need the Q♦ or the J♥, he's doubled in the hope of getting a spade lead (dummy's first suit) which indeed beats the slam.

[han]

Also, west, a beginner, led a low diamond. That's unlikely from 6 small.

And you believe West would lead a diamond from the queen against 6NT after partner's double?
Well if West is a novice you maybe right, but otherwise even mediocre tournament players don't do this in my experience.

I guessed where to put it; my mistake.

(Thirty-one IMPs are on the line.)

Double in this situation is asking for a spade lead, so I would play for two hearts two diamonds 6 clubs and we should have a squeeze of some kind if the the hearts don't break. At trick two play a low heart to the ten, if this holds cross back and play a heart to the queen.

[phil_20686]

For once i disagree with rainer: Rho can just keep three hearts one diamond and Kx of spades. Even if they return the Q of diamonds, you will still be forced to take the heart finesse.

---

Suppose now you play a heart to the K, rho wins and returns a diamond, and you have 6 clubs 1s 1h 3d, and still need another. To do right in this position you need to guess whether to cash the diamond before playing a heart to the K. Then, if you guess this right, you still need to guess whether they bared the spade K, which will not be hart play to find.
