#1 We did play support X as mandatory #2 Weak 2 requirement is quite harsh, at least 2 top of 3 honors to open weak 2. #3 3C over 2D is good hand with invitational values as we dont have something like Good Bad 2NT.
[hv=d=w&v=b&s=s54hq65dqjt43cqt3]133|100|Scoring: IMP[/hv] LHO open 1NT (15-17). Partner double for penalty. RHO 2H to show 2 majors (could be 44M). What do you bid ?
