BIL individual , no agreements SAYC. I attended a BIL teaching session which advocated that X does not show both majors, not even 4-3.
I planned to bid 3♣ over 2♠. Then I would have shown ♥suit, ♣support and invitational values, right?
Then came the unexpected 3♦ bid and well .. they stole it down 2.
- If you play that x does not show both majors, does 3♣ deny a major?
- If I bid 3♣ is p's 3♥ a ♥suit or just control showing looking for 3NT?
- Is it common or uncommon to play that 1mi - 2mi - x does not show both majors (say with a random BBO partner)?

Help

p - 1♣ - 2♦ - x
p - 2♠ - 3♦ all pass
