D and A two-level opening bids           A complete scheme for multi twos. Devised, I believe, by Derek Tyms and Gerard ( Ado ) Hardy.           2♣ = 21+ with ♣'s or     18-20 balanced or     24+ balanced or     weak with 6 ♥'s or 6 ♠'s         responses: 2♦ = relay       after 2♣ - 2♦, then 2♥ = weak with 6 ♥'s   2♠ = weak with 6 ♠'s   2NT = 18-20 balanced   3♣ = 21+ with ♣'s   3NT = 24+ balanced         2♦ = 21+ with ♦'s or     21+ any 4441 distribution or     weak with 5 ♥'s and another suit         responses: 2♥ = less than opening values, assumes partner is weak.   2♠ = looking for the 2 nd suit, 0 or 1 ♥, less than 15 pts.   2NT = 15+ points       after 2♦ - 2♥ , then pass = weak with 5 ♥'s and another suit   2NT = 4441*   3♦ = 21+ with ♦'s (usually 6 card suit)         after 2♦ - 2♠, then pass = weak with 5 ♥'s and 4/5 ♠'s.   2NT = 4441*   3♣ = weak with 5 ♥'s and 4/5 ♣ 's.   3♦ = weak with 5 ♥'s and 4/5 ♦'s   3NT = 21+ with ♦'s (usually 6 card suit)       * after 2NT showing 4441, then 3♣ asks and opener bids the short suit (3NT= ♣'s)     2♥ = 21+ with ♥'s or     weak with 5 ♠'s and a minor         responses: 2♠ = two ♠'s; opener passes with the weak hand type.   2NT = 15+ points   3♣ = looking for the minor (pass or correct)     2♠ = 21+ with ♠'s or     weak with both minors         responses: 2NT = 15+ points   3♣ = looking for the minor (pass or correct)   3d = weak with ♦'s     2NT = 21-23 balanced         responses: Stayman and transfers or whatever you prefer.                 Defence against D and A twos     As with the multi 2♦, it's usually best wait until declarer's hand type is known.             Pattaya Bridge Club - www.pattayabridge.com
