2Diamond Forcing to Game Stayman

Forcing Stayman bidder knows that partner does not have a 5 card major and another 4 card side suit. Opener will only get a chance to show his 5 card suit if responder asks for further clarification of the hand. When opener has a 5 card major and the bidding goes 1NT - 2Diamond - 2Heart - (New Suit), Opener now does not rebid his 5 card major but shows support (or lack thereof) for responder's suit. Responder must also keep in mind when they have a game forcing hand that partner may have a 5 major when opening INT. It is a simple process after opener shows he has at least a 4 card major to find out if they have 5 by bidding 2NT as a further inquiry.

1NT - Pass - 2Diamond Forcing to Game, does not promise a 4 card major.
