BR 27.1 - Bidding after a 1 NT Opening bid

The 1NT Opening shows 16-18 points and a balanced hand (4333, 4432 or 5332).
Originally the idea of a suit transfer after a 1NT opening bid was to keep the strong hand . . . . . . . . when playing in a . . . . contract determined by Responder's (usually) weak long suited and unbalanced hand. Over time however this idea has been utilised to describe both Responder's and Opener's hand in . . . . . . . than possible through the traditional responses to a 1NT Opening.
There are several transfer conventions used these days, the one presented here is very effective and probably the most popular one.

The first responses to a 1NT Opening bid are :

• 1NT - 2♣   = . . . . . . . , asking for Opener's . . . . . . suit

• 1NT - 2♦ = transfer to . . . . . . .   (or 3 . . . . when . . . . with a . . . trump fit and outside . . . . . . )

• 1NT - 2♥   = transfer to . . . . . .   (or 3 . . . when . . . with a . . . trump fit and outside . . . . . . . )

• 1NT - 2♠   = . . . . . . : are you . . . . . . or . . . . . ?

• 1NT - 2NT = '. . . . . . ' : Opener must bid . . . . . . !

• 1NT - 3NT = . . . . . points, balanced or semi-balanced with no 4-card . . . . . (unless . . . . . )

• 1NT - 3♠   = . . . . . transfer, strong hand with 6+card . . . . . . .; suite and . . . . interest

• 1NT - 4NT = . . . . . . . or . . . . . . . .

The above bids also apply after partner's . . . . . . . . .

The use of the 2♠ response as a . . . . . . . . make the traditional invitation responses of 2NT (invitation to Game) and 4NT (invitation to Slam) . . . . . . . . . Those two bids are therefore utilised here for . . . . . . . .
