User:Brian/Bridge/Subsequent bidding after an inverted minor raise
Inverted minor raises are alertable. A raise of the minor implies that no major suit fit can exist, so the partnership must play in either the minor suit or notrump. With stoppers in all suits, a 3NT game is preferable to a 5m game, since making a 5m contract requires additional strength.
Stopper-bidding sequences
In order to determine whether a notrump game is advisable, partners bid stoppers up the line. Once stopper-bidding has commenced, rebids by either partner are as follows:
- With game-going strength and all remaining suits stopped, one signs off in 3NT.
- With all remaining suits stopped but not knowing whether one has enough strength for 3NT, one bids 2NT. Partner then signs off in 3NT with enough strength, or 3m otherwise.
- Otherwise, one either bids a stopper they have in a remaining suit (allowing partner to continue bidding stoppers up the line) or signs off in the agreed minor, whichever is cheaper.
Opener's rebids
My partner single-raised my minor, I have a minimum (13- HCP), and partner is a passed hand → Pass.
My partner single-raised my minor, I have a minimum (13- HCP), and partner is an unpassed hand → Respond 3m. Subsequent bids by partner show are stopper-showing (see below) and indicate game-forcing strength (14+ HCP).
My partner single-raised my minor, I have 14–15 HCP, and stoppers in the other three suits → Rebid 2NT, invitational to 3NT.
My partner single-raised my minor, I have 16+ HCP and stoppers in the other three suits → Rebid 3NT, to play.
My partner single-raised my minor, I have 15- HCP and stoppers in the other three suits →
