7-5 Come Alive?--Updated

Most have probably forgotten this hand as well, but here is the conclusion. At the table I held the 7-5 hand and, while my high card strength was considerably underweight for my bidding, my defense was actually quite good--two sure tricks and a side void. Partner's double here was clearly the "I doubt they can make it" variety, and with no certain fit, I decided not to argue. My partner had Qx xxxxxx AQJx x and we defeated the contract two tricks on the ace of clubs lead. One hand doesn't prove much, but overall I thought we judged this one pretty well.


I may never again have the chance to contemplate defending a 3-level partial with a good 7-5 hand, but I faced this situation on Friday evening as South, 4th in hand with only E-W vulnerable:

AJ9xxxx
Surprisingly, the auction started quietly with two passes to my RHO, who opened 1 Diamond. I overcalled 2 Clubs, LHO made a negative double, partner passed and RHO bid 2 Diamonds. I bid 2 Spades, LHO competed to 3 Diamonds and partner doubled. What now?

Play 4 Spades--Updated

At long last, an update on this hand.

I believe that the line suggested in the comments is best--the key play is discarding from dummy at trick one. Now you can play a club up and decide the later play, taking tricks/discards on the clubs or playing on cross-ruff lines depending on how the opponents defend. Not a particularly difficult hand, but often it is right in this position to ruff preserving the ace to stop a later assault in this suit--I don't think that is right here because the third spade in dummy represents an "entry" of sorts to the long clubs. No guarantees on this hand (the suggested line worked on the lie of the cards, lho holding the ace-fourth of clubs) but it is a good example to remind us that there isn't a "rule" that will cover every situation in the play of the cards.

Suppose you hold this hand in 3rd seat:

Everyone has something to say: partner opens 1 Club, RHO overcalls 1 Heart, you bid 1 Spade and LHO cuebids 2 Spades. Now partner bids 3 Diamonds, you try 3 Notrump and partner corrects to 4 Spades. LHO leads a small heart...do you ruff or discard from dummy and what is your general plan?
