Checkback Stayman

A method of checking on distribution and strength after a 1NT rebid by opener (some pairs play it after 2NT as well).  It is normally treated as an invitational call, so openers replies to Checkback Stayman indicate both strength and distribution.  Normally openers first responsibility is to show 3 cards in partners suit.  A possible treatment might be:

North        South
