My partner and I are relative novices and play Benji ACOL. My partner had a balanced hand (3343) with 28 HCP, and I held a balanced hand (4333) with 5 HCP. Partner opened 2 diamonds (25+HCP balanced) , I
responded 2 hearts (0-5 HCP), partner rebid 2NT (we play Stayman & Transfers), I responded 3NT showing no majors, and partner passed. We took 12 tricks, as our 33 HCP count suggested. How should we have bid? If partner had bid 4NT would she have been asking me to bid 6NT with 4-5 HCP or pass with 0-3 HCP?
