       |   RESPONDER:
       |   A QUICK TRICK (QT) IS AN Ace OR KQ. IF RESPONDER HAD EVEN 1 QT, HE 
       |   CAN THINK ABOUT GAME. HIS FIRST BID WILL BE 2D 2H, 2S, 2NT OR 3C     
       |   & PROMISES NOTHING ABOUT QUICK TRICKS.
       |   WITH  4+ HEARTS, HE WILL BID 2H.
       |   WITH 4+ SPADES or  4+ SPADES & 4+ HEARTS. HE WILL BID 1D.
       |   His 2S BID IS A TRANSFER TO 2NT.  
       |   WITH A 5+ CARD CLUB SUIT & 1 QT, HE CAN TRANSFER TO 3C BY BIDDING 2NT. 
       |   AFTER HIS FIRST BID HE CAN "PASS"  OR REBID DEPENDING ON HIS POINT COUNT.   
       |   IT IS NOT NECESSARY FOR RESPONDER TO SHOW POINTS OR CONTROLS. 
       |   WITH TRANSFERS, HE HAS ABILITY TO KEEP THE BIDDING GOING BY VIRTUE OF
       |   HIS ABILITY TO "PASS".
