After:

1NT Pass 2 Pass
2 Pass Pass Double
Pass 3 3 All Pass

You lead the K, continue with the Q wich is overtaken by partner who continues with another club, on winnig the J, what do you return?

I want to know what spots partner plays and what our methods are.

If you play obvious switch then partner encourages on the opening lead for a heart and discourages for a diamond. Given that partner could switch to diamonds the discouragement and lack of diamond play would then suggest playing the fourth club whereas encouragement would suggest playing a heart now.

The problem with all of this is that partner didn't know how many clubs were cashing. Perhaps there is a clue there but I don't know what it means.

Maybe I'm having a slow moment, but someone explain to me how a 4th club yields an extra trump trick with partner holding anything other than AJ tight (J9 for example)?

AJ and possibly when pard has J9x on a pseudo-promotion.

agree with heart.

if pd wanted a promotion, he could've dropped his red ace (if he had one, and didn't have Q) and then play 3rd . that makes it down two so i doubt that's the case but i find that an important concept.

Suppose partner doesn't hold a red ace? Certainly, if partner holds the AJ doubleton of spades and no red ace, the only way to defeat 3 is by playing the fourth round of clubs (assuming declarer does not misguess the spade suit).

Pard can't have 3s. Pard needs exactly AJ for a true trump promotion and exactly J9 for a pseudo-trump promotion if declarer finesses (which he probably will) but on any other holding, this line seems futile. If this were at the table, we'd all have returned a heart within a few seconds. It's only because it's a book problem we're considering the trump promotion. I hate problems like these.

I really think playing pard for a strong heart holding is playing partner to have made a mistake at T1.

If you want to go passive and try for two additional tricks thats a different matter, but it's very reasonable.

RHO has 12-14, we have 6 and LHO has 8, That leaves 8-10 for pard (after the A) so there's room for 2 aces or an A / KQ.

The OS suit is diamonds, but that doesn't mean an encouraging club would call for a heart.

The only way to get a heart shift playing OS is for pard to play an unusual club spot.

Why is that? If partner has A and AQ, he knows we are only beating this if three clubs are cashing. If he discourages at trick one, how can he know we are going to switch to hearts rather than spades?

Edit: oops I missed this was a weak NT. Hmm will rethink.
