Relay bids over opener's rebids of 2{{Diams}}, 2{{Hearts}}, 2{{Spades}} allow shape to be defined further if attempting to find 5-3 major fits. Advantages are responder's shape, which may be any distribution, is undisclosed, and responder is able to locate suit shortage holdings not suitable for notrumps.
