You have a good auction for once to everyone's favourite contract (come on, admit it). How are you going to play?

Opponents silent throughout. 2C (FG or 20-22, may include singleton honour)-2NT(clubs)-3NT (bal, no club fit)-4C-(minorwood)-4D(3)-4H(QC?)-4S(yes and KS)-4NT(PCK)-5D-7NT

[Evies Dad]

I can come up with one simple plan.
E.g.Hearts 5-2 to West.
If E has 5 clubs neither defender can retain 3 diamonds after AH, QC, cash Spades, heart to the K, cash top clubs.

Hearts 4-3 is more things to consider.
Will get back to you.

Initial reaction. If RHO has 5+ ♣s, declarer can execute a 3-2 compound squeeze, on any lead

squeeze with no count. east hand squeezed east with 5♣/5♦. so play ♥A, ♣Q, ♦A, ♠Q, cash remainder of ♠s, then ♥ to K. east is lost, discard ♦ dummy ♦ are good, discard ♣ then declarer ♣ is good and ♦K is 13th trick

You need to be careful with that construction there is a guard squeeze that operates if E discards all his diamonds allowing you to finesse the 6 later after playing JQK, what if W has the 8 or 7 ?

Good point Cyberyeti but you only need the guard-squeeze if West leads a ♥

++++++++++++++++++++++++++++++++++++++++++++
There also seem to be clash-squeeze possibilities, on any lead
Here, GIB vouchsafes that you must win a ♥ lead with dummy's ♥A.
I don't know how you would suss out a winning line at the table

[Evies Dad]

Ah. So keeping QC as an entry to test one round of Diamonds first is an improvement.
Forces E to transfer heart cover back to West.
I couldn't work that out.

I think it is right to win the heart with the ace. Now it is not necessary to cash the ♣Q and indeed is fatal. Instead cash four rounds of spades. East who began with five clubs and ♦Qx is squeezed on this trick and forced to part with a heart. Now you cash the ♣Q, cross to the ♥K and run three more clubs squeezing West. And I don't think you are giving anything up by doing this as you still have all the simple squeezes. And I think it is wrong to cash the ♦A early as well. Dipak Finesson, the strong Indian player born in Iceland, played this way ... (Believe that and you will believe anything).

---

Oh ... and thanks for the upvote, Nigel. And on a club lead, you play much the same but you must not touch hearts too soon. So play four rounds of spades. Again East is squeezed out of a heart. Now cross to KH and run clubs squeezing West.

[nige1]

On a non-♥ lead, when East has 5+ ♣, you don't need to rely on a clash or guard-squeeze.
The ♦quacks don't affect the play.
Win the opening lead and cash 4 ♠s, discarding a ♣.
East must keep his ♣s -- so must abandon a red suit

---

If East abandons ♦s cash ♣Q, ♦AK, ♥K, ♣s to reach this 3 card ending.
Cashing ♣J completes the non-simultaneous double-squeeze

---

If East abandons ♥s, you reach this similar ending. Again ♣J completes the non-simultaneous double-squeeze

But surely the expert defenders will always lead a heart to attack the pivot suit ... This is the expert forum, not the beginner or novice one ...

Lamford implies that experts self-kibitz
Either or neither red-suit could be a pivot suit
It depends on which suit has honours split between the North-South hands
For example, in the layout above, both red-suits are pivots and there is no defence

I can think of many descriptions for defenders who know to lead heart to attack the pivot suit, but expert isn't one of those words.

[lamford]

I was not suggesting experts self-kibitz. Only a few days ago I was on a hearing into a player who had made 7NT here:

---

West did lead a heart, but there was no defence on any lead, and you will have no problem constructing the layout. Of course you would not be able to discern the heart pips, unless I tell you that East's were all higher than West's.

We found unanimously that there was no evidence whatsoever of self-kibitzing. Declarer had played for the only possible layout and come up trumps (metaphorically that is).
