===Stayman sequences===
If partner responded 2&clubs;, it is Stayman, asking for a 4-card major.

I have 4+ hearts → Bid 2&hearts;.
* If partner responds 2&spades;, it means they have 4 spades, 3- hearts, and invitational strength. Sign off in 2NT, 3&spades;, 3NT, or 4&spades;, depending on your strength and whether you have 4-card spade support.
* If partner responds 2NT, it means they have no 4-card major (the Stayman was "fake") but invitational strength. Pass or sign off in 3NT.
* If partner responds 3&hearts;, it means they have 4+ hearts and invitational strength. Pass or sign off by raising to 4&hearts;.
* If partner responds 3&spades;, it is a slam try showing agreement in hearts. Alert partner's bid. With a minimum, respond 4&hearts;. If partner bids again, it is a [[User:Brian/Bridge/Control bidding|control bid]] or [[User:Brian/Bridge/Responding to Blackwood|Blackwood]]. With a better hand, initiate control bidding or bid 4NT, [[User:Brian/Bridge/Blackwood|Blackwood]].
* If partner responds 3NT, it means they have game-forcing strength, 4 spades, and 3- hearts. Pass or sign off in 4&spades.
* If partner responds 4&hearts;, it is a sign-off.
* If partner responds 4NT, 5NT, 6NT, or 7NT, it is [[User:Brian/Bridge/Quantitative notrump raises|quantitative]] and shows 4 spades. Pass or make a sign-off either in notrump or spades.

I have 4+ spades → Bid 2&spades;.
* If partner responds 2NT, they show invitational strength without 4-card spade support. Pass or sign off in 3NT.
* If partner responds 3NT, they show game-forcing strength without 4-card spade support. Pass.
* In all other cases, the subsequent bidding is the same as in the previous paragraph, but exchange "spades" and "hearts".

I have no 4-card major → Bid 2&diams;.
* If partner responds 2M, they show invitational strength with 5 of the bid major and 4 of the unbid major. Sign off in 2NT, 3M, 3NT, or 4M, depending on your strength and whether you have 3-card support for partner's 5-card major.
* If partner responds 2NT, they have invitational strength. Pass or sign off in 3NT.
* If partner responds 3M, they show game-forcing strength with '''5 of the other major''' (oM) and 4 of the bid major. With 3-card support for oM, raise to 4oM; if partner bids again, it is a [[User:Brian/Bridge/Control bidding|control bid]] or [[User:Brian/Bridge/Responding to Blackwood|Blackwood]]. Otherwise, rebid 3NT; if partner bids again, it is a [[User:Brian/Bridge/Quantitative notrump raises|quantitative raise]].
* If partner responds 3NT, it is a sign-off. Pass.
* If partner responds 4NT, 5NT, 6NT, or 7NT, it is [[User:Brian/Bridge/Quantitative notrump raises|quantitative]].

===Jacoby transfer sequences===
If partner responded 2&diams;, it shows 5+ hearts. If partner responded 2&hearts;, it shows 5+ spades. In either case, announce "transfer" when partner makes their bid.

I have 17 HCP with 4+ of the major above → Announce "transfer" then superaccept by bidding 3 of the major. (TODO)

Otherwise → Announce "transfer" then accept by bidding 2 of the major above. (TODO)

===Other responses===
A notrump response is [[User:Brian/Bridge/Quantitative notrump raises|quantitative raise]]. Most commonly, this will be 2NT or 3NT. 2NT is invitational to 3NT, while 3NT is to play.

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

My partner responded 4&diams; or 4&hearts; → Announce "transfer" then accept the transfer by bidding 4 of the next suit. This is a ''Texas transfer''. (TODO)
