===== 2-under general description ===== 

  * 1!C is strong (usually 14+ in the first 2 seats, 17+ in 3rd and 4th)
  * 1nt is weak in the first two seats 10-13; 3rd and 4th seats 14-16
  * all the bids from 1!D to 4!D (except for 1!H, 1nt, 2!H and 3!H) are 2-under, showing the n+2 suit, unbalanced hands and denying unbid 4+ card major(s); intermediate range (8-13 usually in the first 2 seats) - in 3rd and 4th seats the HCP range can vary from 0 to 16
    * the n+1 response is always a relay asking for description
      * n response = minimum hand
      * anything else = natural, maximum hand
    * 2nt, if available = 4 card fit, inv+
    * new suit = non-forcing (strong hands bid n+1 first)
  * a double by responder is not negative, but proposing a penalty 
    * new suit: 10 cards in the two suits bid or singleton in the doubled suit
    * normally should accept the penalty proposal
  * a reopening double shows a singleton in the opponents' suit (so a penalty pass is also allowed, in addition to the penalty proposing double)
  * handy conventions that fit nicely: rubens, various forms of lebensohl, fit jumps; we don't play SWITCH in this system
  * signals: UDCA; discarding: UDCA; priorities always: Count/Attitude/Suit Preference; we give Count often
  * leads: always 2/4; top of sequence; J from KJT

        * 2nt = never used
      * 1!S, 1NT, 2!C, 2!D, 2!H = nat, 14-17
        * normal structures apply (fit bids after 1!S and stayman+transfers after 1nt)
    * 1!H, 1!S, 2!C, 2!D = 10+, nat
    * 1nt = 10-13
    * 2!H, 2!S, 3!C, 3!D = weak, constructive, 6-9 hcp
    * 2nt = 14+ 

===== 1!D Opening =====

    * 1!D = 4!S exactly
      * 1!H = relay (denies fit)
        * 1!S = 8-10 hcp
        * other, natural, maximum
      * 1!S = to play, 3!S
      * new suit non-forcing (use relay for strong hands)
      * 2nt = inv+ 4!Ss
    

===== 1!H Opening =====
    * 1!H = 4!H exactly
    * 1!H - 2!H = 4!H, weak
    * 1!H - 2nt = 4!H, inv+
    * minor rebids show 5+ cards in the minor
    * 1!H - 1!S = 5+ cards, forcing 1 round
    * 1!H - 1nt = relay, forcing
          * 2!C/2!D = 5 cards, nat
          * 2!H = 4441, singleton !S
          * 2!S = 5440, 5!C, !S void
          * 2nt = 5440, 5!D, !S void
          * 3!C/3!D = 6 cards, nat
    * 1!H - 2!C, 2!D = nat, non-forcing
    

===== 1!S Opening =====
    * 4+ !Cs, usually 54 in the minors
      * 1nt = to play
           * opener is allowed to rebid 2!M with a 3 card suit and a nice hand (singleton in the other major)
      * 2!C, 2!D = to play
      * 2!H, 2!S = nat, forcing
      * 2nt = bid your best minor (can be strong)
      * 3!C/3!D = weak
      

===== 2!C Opening =====
    * 2!C = 5!H, 8-13 hcp, unbalanced
      * 2!D = relay
        * 2!H = minimum hand
        * anything else = natural, maximum
      * new suit non-forcing (use relay for strong hands)
      * 2nt = 4+ card fit, inv+
      * fit jumps
      * 3nt nat
      
      * 2!D, 2!S, 2nt, 3!C, 3!D, 3!S, 3nt, 4!C, 4!D openings have a similar structure
      

===== 2!H Opening =====
    * 2!H = 4-4 / 5-4 majors, 8-13 hcp
      * 2nt = relay
        * 3!C = 4!Cs
        * 3!D = 4!Ds
        * 3!H = 5!Hs
        * 3!S = 5!Ss
      * 3!C = inv+, !H fit
      * 3!D = inv+, !S fit
      

===== 3!H Opening =====
    * 3!H = 5-5 / 6-5 majors, 8-13 hcp
      * 4!C = relay
        * 4!D = 5-5
        * 4!H, 4!S = 6 cards      

===== If they X our transfer =====
    * pass = to play
    * xx = relay
    * 2nt = inv+, fit
    * fit jumps
    * new suit non-forcing


===== If they X our 1NT =====
    * XX = inv+, 12+ hcp, establishes an unlimited forcing pass sequence; subsequent doubles are for penalty
    * new suit = non-forcing, 5 cards, partner can raise with 4 cards
    * pass = non-forcing, denies a 5 card suit; subsequent doubles are for take-out
    * 1nt - [X] - pass - [pass] - 
       * pass = 4333 shape
       * new suit = 5 cards
       * XX = 2 4-card suits
          * try to find a 4-4 fit economically
