There is no Smolen transfer for this type of hands. If North shows a 4⁺ suit in ª, South can make an invitational raise. After 2¨, he bids 2ª, showing 5ª, 4© and less than invitational values, i.e. 0-7 hcp. North's ultimate try for game is understandable, but South cannot accept it. He should have some singleton beside his 7 hcp.

South cannot bid this way when 2ª is a relay. In that case, he should bid 2©, or transfer to 2ª, hoping to hit the best fit..

Given the stiff ¨K, East has no reason to invite with 2NT or 3§, if that is played as forcing to 3©.

Some partnerships play negative free bids (5⁺ suit, 8-11 hcp) all the way. North has nothing left but to rebid 2¨ on a 3-card suit.
