Playing 15-17 5542 (but would open 1♦ with a balanced hand with four diamonds), Walsh (but apparently this 1♠ rebid doesn't promize an unbalanced hand), responder's 3♣ at second turn is apparently forcing (Pavlicek style or some such, not really worked out in details). 4♣ is available as minorwood from either side. North could also start with a splinter or an inverted raise although that in principle denies a four-card major.
Slam is not bad. Clubs 2-1 and either ♠K or ♦A in the right place would give you some 57% and depending on opps' skills and clues from the bidding you may have additional chances, such as for example West leading ♦A (it was matchpoints after all).
Should either partner have done something?
Would it be easier if we were playing your favorite system?
Jasmine ♣
With slow red-suit stops and weak ♣ support, it's hard for South to show slam-enthusiasm.
