User:Brian/Bridge/Responding to 2C
The most common set of responses to a strong 2♣ opening are as follows:
|I have 8+ HCP with a balanced hand||Respond 2NT. If opener rebids notrump, it is quantitative.|
|I have 8+ HCP with a good 5+-card major suit (at least 2 of 3 top honors)||Bid your suit at the 2 level. If partner raises your suit, follow up with a control bid or 4NT, Blackwood.|
|I have 8+ HCP with a good 5+-card minor suit||Bid your suit at the 3 level. If partner raises your suit, follow up with a control bid or 4NT, Blackwood.|
|Otherwise||Bid 2♦ (see below).|
The 2♥, 2♠, 2NT, 3♣, and 3♦ responses are said to be "positive", since they show the presence of some quality of responder's hand. The 2♦ response is "waiting", an artificial relay that denies the positive responses and asks opener to describe their hand. Thus, 2♦ is like a "catch-all" response, used for the following kinds of hands:
- Less than 8 HCP, for example ♠J872 ♥643 ♦J2 ♣KT97
- Unbalanced with a low-quality suit, for example ♠KT985 ♥A63 ♦5 ♣Q765
- 4441 distribution regardless of strength, for example ♠KQT2 ♥4 ♦K754 ♣AJ93.
|Partner rebid 2NT||See responding to a 2NT opening.|
|Partner rebid 3NT and I have a 6+-card major|| Make a Texas transfer by bidding 4 of the suit below the major. If you have slam interest, follow up with a control bid or 4NT,
Blackwood after partner accepts.
|Partner rebid 3NT and I have 7 HCP||Make a quantitative raise to 4NT.|
|Partner rebid 3NT and I have 6− HCP||Pass.|
|Partner rebid 4NT, 5NT, 6NT, or 7NT||These rebids show balanced hands with 28–30, 31–32, 33–36 HCP, or 37+ HCP, respectively. Either make a quantitative raise or pass.|
|Partner bid a major suit and I have 3+-card support with a weak hand||Raise to 4M. If opener has a very good hand, they might still bid a control or 4NT, Blackwood.|
|Partner bid a major suit and I have 3+-card support with slam interest||Raise to 3M.|
Details of subsequent bidding not covered here vary greatly according to partnership agreement.
