There's been a lot of buzz, but I believe it's time to give this a try for real. An opening bid at the two-level does not mean what it used to. Memorize what follows (or comment with quibbles and alternate suggestions).
Open 2D, 2H, or 2S if you have exactly six cards in the suit and
With a strong hand, open 2C. This promises 20 or more points (or a couple less with a great strong suit) and says nothing about your club holding.
Responses to a weak-two opening
You're not forced to respond.
- With a doubleton at least in partner's suit and 7-13 points, you can raise in the same suit. Opener should pass.
- With a longer fit and greater than opening strength, jump to game.
- With a five-card suit and good point count, bid that suit. To bid at the three level, you should have a six-card suit and/or 15+ points.
- To invite partner to game, bid 2NT.
This promises 14+ points and invites the opener to show a feature in another suit -- an ace, king, void, or singleton -- by bidding that suit at the three level. If opener has none of the above, she rebids the original suit. If the original suit is rock-solid -- headed by three honors, say -- she can rebid 3NT.See Ogust.
- To invite partner to slam, bid 4NT: Blackwood!
Responses to a 2C opening
You are forced to respond.
- With 7+ points and five diamonds, hearts, or spades, bid that suit at the two level.
- With 7+ points and balanced distribution, bid 2NT.
- With less than seven points and/or no particular suit you like, bid 2D. Opener will name her favorite suit. You are still forced to respond -- raise that suit to the three level if you like it okay and have five or more points, or bid 3C as a sign-off if you have very low points and nothing else to offer.
