I had this hand yesterday.
We play Benji weak 2 Hearts/Spades with a strong 2♦.
I understand that 2♣ requires 8 playing tricks, and for long suits the ace, king and queen are counted together with all cards in excess of 3 in the suit; for short suits, only clear winner combinations are counted, and a Singleton K does not count as a playing trick. i don't have any long suits, but if I assume 7 playing tricks in the majors (hoping one will break) that still leaves me with only 7 playing tricks.
Should I open 2NT, or if I open 2♣ and partner responds 2♦(relay) do I rebid 2NT or 3NT?
