Weak Two Bid?
Sometime back in the 1960's the experts and the younger player in the bridge world adopted weak two bids to the consternation of the old-time players.  They didn't like 'em!  They didn't use them and they they didn't know how to defend against them, either.  We still use weak two bids with the majors, but the majority of players no longer play a weak 2 convention simply because it's not effective anymore.  Many players say, "The bid gives the opponents a road map of the hand... they know the shape and point-count and they still have room to find their major-suit fit."
    Weak Two Diamond Bids are No Longer Effective!
Other Agreements
If you are a Flannery fan where an opening bid of 2 shows 11-15 points with five hearts and four spades you have found a better use for the bid.  Also popular is the Mini-Roman bid, where opening 2 shows 11-15 points but with a pattern of 4-4-4-1.  Most players agree that the hand must have a 4-card spade suit, but not everyone.  Other than a weak two bid, these might be the two most popular conventions for this call, but there are others as well.

Natural With an Opening Hand
Not very well known, but there is a treatment you should be aware of...
  • At least a 5-card suit with 11-15 HCP
  • No 4-card major
  • Responder's 2-level bids are highly invitational but not forcing
  • Responder's 3-level bids are game forcing
  • Responder's double of an overcall is not negative (Opener does not have a major)
This treatment (it's not a convention) has the safety of having opening point-count and has better preemptive value against the opponents majors. (Because of the announced strength)  It's also descriptive, which means responder has a better idea of what he can bid and whether or not he can double for penalty.

If you play this treatment you will discover that it has a high frequency of occurance and you will use it often.  Flannery, on the other hand, or the mini-Roman bid, occurs much less often.

This treatment is popular with Precision players and strong club bidders because it is similar to the 2 bid that is part of their system, but it works very well with 2/1 system players as well.

If you are looking for a replacement bid for a weak two diamond call, consider this treatment.

Oh, and just because you pick up a hand that fits the agreement you shouldn't automatically open 2 with it - these are the hands where you don't mind rebidding 1NT if partner responds with a major.

Open 1 with this hand and rebid 1NT if your partner responds 1 or consider raising a spade response.  (Yeah, with 3-card support... they are as good as four small ones.)

And don't forget to alert the bid!
