and waited in trepidation for it to be passed
You know partner cant / wont pass this.
Your chances are to pass and score a few under ticks, or balance with 2NT, more or less this strength at this position, but usually less S.
Partners initial pass is quite revealing. You know their hand is short in S, and with 10-11 HCP, which youll need for 3NT, they might have tried a TOX with a 3-suited hand, probably converted by you, or bid a long suit should they have one.
Actually, if you bid (2NT or worse, X), it is likely you (or partner) will end up in a bad contract. It looks like the declaring side on this deal will be in a lousy spot. And currently, opps are sitting right there. Dont fancy taking their place.
So Id pass (ready to apologize if I turned down 7 IMPs or so). Sometimes, not bidding is more dangerous than bidding, but I dont think it is the case here.
Of course, if opps routinely open a 5-cd suit weak 2 and partner can have an average balanced hand, youll be favorite for 3NT and wont get rich scoring NV under tricks when in the other room it went pass pass pass 1NT 3NT or some other sequence starting with 1S.
