Simple, or not....

[manudude03]

One of my opps had this play problem earlier today.

You get the ♣3 lead (playing 2nd/4th). Plan the play.

 

If you test diamonds

You find RHO started with 4 of them, LHO pitching a high club.

 

 

If you ever decide to play the queen of hearts on the first round of hearts, RHO will drop the jack.

 

Bonus question:

How often should you falsecard from J9 or J9x?

 

[sfi]

Do we know anything about the bidding or final contract?

Sorry, thought I had included it, the contract was 6NT (2NT-4NT-6NT) OP edited.

[broze]

Playing against any semi-competent opponent playing for the drop is clear since it picks up J9x and J9

 

And as for the bonus question surely the answer is "always" as it is the only play that gives declarer a losing option.

[sfi]

Next question - what happens on the clubs? If RHO ducks, I'm playing a second club and I'll watch the spots to try and work out the distribution.

[JanisW]

I'd play for the drop, too.

 

And by the way 4NT directly is terrible.

But unfortunately one never sees the Opps missing their 9 card Heart-Fit, does one?

I don't know the answer, but if you always play the J from J9(x), then if you ever play the 9 from whatever holding, then declarer would know to finesse as either the jack is onside or the contract is hopeless.

[sfi]

If the Jack is a singleton, LHO has chosen to lead a low club from something like:

 

Jx

9xxxx

xx

Axxx

 

Two issues with taking the finesse:

 

1 - I would expect them to lead a heart with this hand.

2 - The double squeeze works if LHO is guarding hearts.

 

So drop it is.

Did West really underlead ♣A, and there are 2 ♣10 played.

Also with diamonds not breaking we only have tricks if we successfully finesse...

 

Are you sure there isn't a squeeze available?

If West holds that hand, there is no double squeeze if you play another high heart but there is a simple spade-diamond squeeze against East.

True, but my second point wasn't really related to the hand I put together. There is a double squeeze no matter what the distribution of spades and clubs, although if West holds that hand then it's really a simple squeeze played as a double. It functions exactly the same way if West holds

where West will have already been squeezed on the third diamond. If the hearts aren't running, East will have to give up the 12th trick when the top hearts are cashed.

 

The point is, once the opponents win one of the first two clubs, you're cold when you play for the drop unless East started with 5 hearts.

The ♥9 falsecard from ♥J9x makes sense.

Here, the ♥J false-card gives you a near cinch, with no need to finesse ♥s.

Start with 3 ♣s, 1 ♥, and 3 ♦s

(Hit Next in the diagram on the left).

Now, as the cards lie, 3 ♥s squeeze RHO in the pointed suits.

If LHO had 4♦s, 2 ♠s would squeeze LHO in the red suits.

Better defence might be for LHO to duck 2 rounds of ♣s.[/hv]

What expertise level? I think a club lead is wrong as partner cannot really have help. A diamond lead might be best and often the underlead of the spade honor will avoid problems later. Clearing clubs could be forcing declarer into the winning heart play, so what happens if the 2nd club is won and then shift to another suit?

 

Excellent problem for partners to go over I would say!

[msjennifer]

The declarer has only 10 top tricks.He has to find 2 extra tricks.In order to think of a three suit simple or double squeeze he will have to rectify the count unless he is thinking of something like a squeeze without count.As it is ,expert defenders are not going to let him do it.They will duck the second club and he is back to square one. So he has to take it on from there.Not at all easy ! My answer to your second question is:ALWAYS.

Against ordinary opponents I might consider the finesse in hearts ,but as I said that will be ,with some trepidation.( if they duck the second club)

[johnu]

The declarer has only 10 top tricks.

 

When the ♥J is played on the 1st heart trick, there are 2 spades, 4 hearts, 3 diamonds, and 2 clubs, which is 11 top tricks.

Before playing any card to the first trick there are only 10 tricks.They become 11 only As and when the declarer plays the HQ and the Jack appears. The plan thought of with 10 tricks originally changes and before that the count needs to be rectified.It can happen ONLY if opponents take the club Acs on the second round of clubs.Declarer does not KNOW that the HJ will fall on the first round of hearts and has to plan accordingly.

Ducking the second club isn't so easy, especially at MPs.

 

You are really going to play the J from J9x? Two problems with that. First off, declarer may be able to get a count on the hand sufficient to tell that you don't have a stiff J. Second, you don't know whether declarer needs 4 H tricks or 5; if it's only 4, you've just handed him the contract. The 9 makes more sense to me.

One of the conditions of the problem is that the opponents take the 2nd round of clubs and play back a club. It still isn't clear who had what clubs since the OP specified 2 ♣10 were played. The question of what to do if the opponents duck 2 rounds of clubs is an entirely different problem.

 

It looks like LHO is a clever player who is leading away from ♣A when RHO doesn't play the ace at trick 1, so I would win the queen, not the jack as specified by the OP, cross to a diamond, and lead a club to the king. Winning the jack at trick 1 and then continuing clubs from hand makes it clear that declarer has at least KQJ so a clever defender who knows something about squeeze play will find it easier to duck. If you cross to ♦K and lead a club to the king there's a better chance that LHO will play the ace.
