Transfers after 2NT
MrQ: This was opponents playing but they ended up in 4♥ with 5-2 fit. We concluded with my partner that in this situation (assuming that any response from North is showing 4/5+ points) South should have bid 3NT to show North that they have doubleton heart and leave it up to North to leave it there if they had only 5 hearts or bid 4♥ if they had 6+ of them. Is this correct?
Guru: Yes, North should rebid 3NT if playing transfers, basic bidding.
