Weak two bid is a treatment for opening 2♦, 2♥, or 2♠ with 5-10 HCPs (7-12 total points) and a long (6+ card) suit. The prerequisite is Strong two clubs, since the other three suits are no longer available for Strong two bids. At this point, weak two bids are in very common use, and a part of the SAYC system. ACBL requires that the point range for weak two-bids be no more than 7 points. The advantage of these weak preempts is that the bidding is still low enough that partner can get back into bidding towards game with an openable hand.
