Constructive conventions:

  • 2-way checkback: after 1X-1Y-1NT

    2C !F relay to 2D to show invitational or sign off in D 2D ! as ordered pass weak with diamonds 2H inv
    1D-1H-1NT-2C-2D-2H shows 5H 1D-1S-1NT-2C-2D-2H shows 5S, 4H 1H-1S-1NT-2C-2D-2H shows 5+S, 4H (with 3H, you'll probably just bid 3H) 2S inv w/5S 2NT inv nat 3C inv with clubs 3D inv with diamonds 3H very invitational, shapely 1D-1S-1NT-2C-2D-3H shows 5+S, 5+H 1D-1H-1NT-2C-2D-3H shows 6+H 3S very invitational, 6+S

    2D !GF shows game force

      in priority:
      bid other major with 4
      bid partner's major with 3
      rebid good 5 card minor
      bid 2NT elsewise
    

    2H to play 2S to play

    2NT !F transfer to 3C for club sign off, or slam try 3C as ordered pass weak with clubs 3D very strong, slam oriented D hand, demands cuebid 3H very strong, slam oriented H hand, demands cuebid 3S very strong, slam oriented S hand, demands cuebid

    3X GF, if rebid, shows a good 6+, otherwise, shows a 5-5 shapely.

Dealing with overcalls:

ODR: offensive/defensive ratio of hand.

  • new suit, natural, forcing by unpassed hand

  • double, negative

  • raise show simple/mixed raise

  • jumps show preemptive

  • cuebid of their suit shows limit+ 3 trump with bad ODR (defensive hand), or 4 trump with very bad ODR

  • 2NT shows limit+ 4 trump, defensive hand

  • jump in their suit shows splinter

  • jump in new suit shows offensive hand, side source of tricks, willingness to play at that level

    1H - [1S] 1NT natural

    2C/2D natural, forcing by UPH
    
    2H    simple/mixed raise
    
    2S    ! limit raise, 3 trump, defensive (or very bad 4)
    2NT   ! limit raise, 4 trump, defensive
    
    3C/3D   ! invitational fit jump
    4C/4D   ! game-forcing fit jump
    5C/5D   ! still a fit jump
    
    3S/4S   ! splinters
    

    1S - [2D]

    2H/3C natural, forcing by UPH
    
    2S    simple/mixed raise
    
    2NT   ! limit raise, 4 trump, defensive
    3D    ! limit raise, 3 trump, defensive (or very bad 4)
    
    3H    ! invitational fit jump
    4C/4H ! game forcing fit jump
    5C/5H ! still more fit jumps
    
    4D    ! splinter
    

    1M - [X] XX 10+, no fit

    2C    !  constructive raise (6-9)
    2M    !  very weak raise (0-5)
    
    2NT   limit + raise
    3C    natural, forcing by UPH
    
    elsewise, fit jumps as normal.
    

Slam bidding:

RKC 1430, specific kings

cuebidding known suit of partner: should be honor cuebidding own suit: shows two of the top three cuebidding your trump: two of the top three

  • 5NT always (except in RKC sequences) pick-a-small-slam (oriented towards minors if no focus)

first/second round controls

  • serious NT

Competitive bidding:

Defense versus NT (Lionel)

versus weak or strong

downgrade X, 2C, 2D by a passed hand, but should have distribution to make up.

X   11+, spades + other or big (19+)
  advancer passes with 9-10+, bids spades or first suit can stand
  

2C  11+, clubs + hearts
2D  11+, diamonds + hearts
2H  hearts
2S  spades
2NT minors
3C  clubs
3D  diamonds
