This poll also applies to the sequence 1♠-2♥-3♠ - the title is chosen for brevity.
Playing 2/1, opener doesn't have to jump in his major suit just to show a strong hand with a 6+ card suit, since a simple rebid of his suit would still be forcing. The jump rebid should therefore show a specific type of hand, although the precise definition is unclear to me. How do people play this sequence nowadays?
For the third and fourth options, my definition of "semi-solid" is a suit that has a better than 50% chance of avoiding more than one loser opposite a void. KQJTxx and KQJ9xxx are examples of minimum suits. If your definition of semi-solid is wildly different from this, please vote for "other".
