Editing User:Brian/Bridge/Rebids after a 2NT opening

See [[User:Brian/Bridge/Responding_to_a_1NT_opening|Responding to a 1NT opening]] for an explanation of the Stayman convention and Jacoby transfers.

This page should also be used after a 2&clubs; - 2&diams; - 2NT "delayed 2NT opening", which shows a balanced hand with 22-24 HCP.

==Stayman sequences==
If partner responded 3&clubs;, it is Stayman, asking for a 4-card major.

I have 4+ hearts &rarr; Bid 3&hearts;.
* If partner responds 3NT, it means they have 4 spades, 3- hearts, and game-forcing strength. Pass to deny 4-card spade support, or raise to 4&spades; with 4+ spades.
* If partner responds 4&hearts;, it is a sign-off. Pass.
* Any other response by partner shows suit agreement and is a slam try: either a [[User:Brian/Bridge/Control bidding|control bid]] or [[User:Brian/Bridge/Responding to Blackwood|Blackwood]].

I have 4+ spades &rarr; Bid 3&spades;.
* If partner responds 3NT, it means their 4-card major was hearts. You already denied 4 hearts, so this is a sign-off bid. Pass.
* If partner responds 4&spades;, it is a sign-off. Pass.
* Any other response by partner shows suit agreement and is a slam try: either a [[User:Brian/Bridge/Control bidding|control bid]] or [[User:Brian/Bridge/Responding to Blackwood|Blackwood]].

I have no 4-card major: Bid 3&diams;.
* If partner responds 3NT, it is a sign-off. Pass.
* If partner responds 3 of a major, it is a Smolen transfer, showing 4 of the bid major and '''5 of the other major''' (oM). With 3-card support for oM, raise to 4oM; any subsequent bid by partner is a [[User:Brian/Bridge/Control bidding|control bid]] or [[User:Brian/Bridge/Responding to Blackwood|Blackwood]]. Lacking 3-card support for oM, rebid 3NT; any subsequent bid by partner is a [[User:Brian/Bridge/Quantitative notrump raises|quantitative raise]].

===Transfer sequences===
My partner bid 3&diams; (showing 5 hearts) or 3&hearts; (showing 5 spades) &rarr; Announce "transfer" and accept the transfer by bidding 3M.
* If partner rebids 3NT, they have exactly 5 of the major. Pass or sign off in 4M with 3-card support.
* If partner rebids notrump at a higher level, it is a [[User:Brian/Bridge/Quantitative notrump raises|quantitative raise]] and shows exactly 5 of the major. Pass or sign off in notrump lacking 3-card support, or sign off in partner's major with 3-card support.

My partner bid 4&diams; (showing 6+ hearts) or 4&hearts; (showing 6+ spades) &rarr; Announce "transfer" and accept the transfer by bidding 4M. Usually, partner will pass. If partner bids again, it is a [[User:Brian/Bridge/Control bidding|control bid]] or [[User:Brian/Bridge/Responding to Blackwood|Blackwood]].

===Other responses===
My partner responded notrump &rarr; This is a [[User:Brian/Bridge/Quantitative notrump raises|quantitative raise]]. Most commonly, this will be 3NT, to play.

My partner responded 4&clubs; &rarr; See [[User:Brian/Bridge/Responding to Gerber|Responding to Gerber]].
