You are playing short matches that are cross imped with three other tables. You are currently winning your match handily so decide to be quite conservative and pass as opener even playing a 12-14 NT. (I know some will disagree with this, but it is not really the question at hand.)
Partner hesitates for quite awhile after the 3♥ bid. Note you would have had an easy double if 3♥ came back around to you. What I was trying to figure out is what my logical alternatives were when 3♠ came back to me. Now I know that I can pose this as a normal UI problem without the hesitation. The question is what my thinking process should be at the table in this regard. I felt that my only LA at the time was to pass. Is this quite straightforward or would you think other calls allowed?
