At imps, it would be useful to be able to bid 3C transfer and then 3N. That should clearly suggest doubt, else one would have bid 3N immediately....as a passed hand one cannot be interested in slam.

Hi Mike, what would 3♣ transfer followed by 3♠ be for you? It seems like we should have enough sequences here to distinguish between shortage, low fragment and half-stopper and I wonder if you have detailed agreements in place for that (or maybe something better).

Depends on your system but Rubensohl is useful here
3C is invitational with Diamonds
Else 3D forcing

fast to 3NT should show no stopper and game values....to each his own......tough between 3♦ or 3NT.....matchpoints I would take a plus in diamonds imps i would try for game
