A rebid by opener in response to a forcing 1NT follows these rules:
Rule 1. With 4+ of the other major, bid them.
Example: 1ª - 1NT* - 2©
Rule 2. With 6 of the original suit, rebid them at the two level or jump to three with an 18+ HCP hand.
Example: 1ª - 1NT* - 2ª
(Either is OK. We usually rebid the six card major first when also holding the other major.)
Rule 3. Bid 2NT with Notrump opener strength
or bid 3NT with 19+.Example: 1ª - 1NT* - 2NT
Rule 4. With none of the above, bid the longer minor.
Example: 1ª - 1NT* - 2¨ or 1ª - 1NT* - 3§
This may be a three card suit, but remember, by this time, the hand is beginning to look like a misfit, and you need to find a safe harbor at a low level. With a strong hand, opener may jump in a long minor, but with caution ... responder may have the other minor.
Clarify, Please. Opener will, on his first rebid, clarify his hand ... a second four card suit, six of the original major, NT or the better/longer minor. The rebid by responder should then set the contract or invite opener to game.
