1NT – Keri


    This is designed in the context of a strong 1NT of 15-18 but will be equal
ly applicable for 15-17. The system permits opening of 1NT with a 5 card major
 but acknowledges, it will miss some 5-3 major fits.
    In the text below openers bids and their explanation will be in black, res
ponders in blue.

1N -  2C (2C is a puppet to 2D)
2D -  ?
      · Pass = diamonds in a weak hand
      · 2H invite with 4 or 5 hearts

                           4S = 4x x x
                           3NT = to play if suitable
                    4H = 5 hearts
      · 2S invite with 4 or 5 spades analogous to 2H above except that
               3H = 25xx and maximum
      · 2NT force to game asking for majors and hand pattern 
               3C no 5 card major and not 4333
                    3D asks for 4 card major (and promises one!)

 x x x at best.
2H -  ?
    · Pass with hearts in a weak hand
    · 2S invite+ with 4H and 5S *different*  (forcing to 2nt at least?).

1N - 2H,    2H transfer to spades with 5+S, unless both majors when 4S and 5H

2S  -  ?
     · pass
    · 3H FG with 4S and 5H *different*



1N - 2S,    range enquiry but implies no 4 card major, OR 6+ card one suited w
ith slam interest.
 ?
2NT all minimums
     · new suit is 6+ and is RKC (3N is subsequent signoff)
     · jump to game in new suit is to play
     · 4NT go on unless absolutely dreadful 
3C all maximums as above but need 4C to show clubs 4NT go on if absolutely max
imum

1N - 2NT transfer to 3C 
3C  -  ?
     · Pass with clubs in a weak hand
     · 3D FG with minors 5-4 either way  
               3H,S stopper here but not other major, to explore 3nt and minor
 fit.
               3NT both majors stopped
               4C,D sets minor

     · 3N x xx5 with slam interest
     · 4C = xx46 and slam interest
     · 4D,4H,4S shows void with good clubs and is voidwood. 


1N -  3C/3D/3H/3S, FG, with single in next suit. Usually 4441,5m440, 5m431, 6m
331   
         (this will jump to 5m if 3N not available). Avoid with 1345 precisely

 ?
· 3NT    =  strong opposite singleton.
· 3H/3S =  offering a 4 card major (perhaps before bidding 3NT so do not bypass it). May

subsequently bid minors naturally if 3N not possible).
     Rebid of short suit shows fit, max, void. 
· 4C/4D natural with no major and 3N not possible.
· 4H/4S with 5 card major since 3 card support is assured
· Bid Short Suit : slam interest with no wasted values.
     new suit = possible trump suit 
· Jump in short suit shows 333 in side suits with no wasted values in splinte
r 4 card suit.


1N -  3C/3D/3H/3S If we play only 5m440 or 4441 (or 6331) then 
 ?
· cue of shortage = no wasted values in that suit
     now responder makes next step bid and
          opener sets suits
               now responder step bid is RKC for set suit 
· bid of suit sets the suit but warns of some wasted values
     now responder step bid is RKC for set suit 
· 3N is to play and warns of considerable wasted values but 2+ stops.
     4C shows slam interest and requires opener to set a suit 
          Opener sets suit (shortage = clubs, 4N = no fit!)
               responder step bid is then RKC for set suit. 

1N -  3NT to play 

1N -  4C transfer to hearts 
     4N is now RKC 
1N - 4D transfer to spades 
     4N is now RKC  

Interference
1N-( X):
     if, X is non-penalty then ignore
     else, normal newlands escapes (XX->2C or majors;2C->2D etc) 

1N-(2C): X = I was about to bid 2C, bid 2D as normal.

1N-(2D) or higher: Lebensohl


1N-( P)-2C-( X) : assuming this shows clubs
 ?   
· 2D as normal but with a club stop
· Pass no club stopper, then responders XX forces 2D.
· XX is to play with good clubs
     pass
     2D is to play
     other bids have normal meaning, as if opener bid 2D. 

1N-( P)-2C-(2D) :
?  
· Pass = opener bidding 2D and everything as normal.
· X = penalty

1N-( P)-2C-(2HS3C) :

· X = penalty but must have diamonds so responder can run to 3D if he has the
 weak hand.
· Usually pass if cannot double and leave it to responder
     when2S,3C,3D would be invite and rest FG (inc. 2NT). 

1N-( P)-2D or 2H - ( X) :
 ? 
· pass = 2 in transfer suit;
· transfer = 3;
· XX = 4.

1N-( P)-2S-( X) : presumably this shows spades so 
· 2N = min + stop
· 3C = max + stop
· Pass = no stop and
     responder XX forces range statement
· XX = play here, I have strong spades


Things to Remember
1N-2C-2D-2NT is a major enquiry 
3H,S shows 5 cards
3D shows any 4333
3C shows all others

1N-2D-2H-2NT (and spade analogue) shows a minor is held and asks for descripti
on
3C shows no fit and asks for singleton
3D shows fit and asks for minor
3M (H in this example) shows strong support and slammy
3OM (S in this example) shows own 5 card suit (no H support)
4M support but no slam interest.

1N-2D-2H-2S is F1 with 4H and 5S 

1N-2H-2S-3H is FG with 4S and 5H 

This facilitates invitation with 5-4 majors by 
1. with 5H and 4S bid 1N-2C-2D-2H and heart fit is found or opener bids 2S/N

2. with 5S and 4H bid 1N-2D-2H-2S and opener will bid 2N,3H,3S with min. And 3
C( H), 3D( S), 3N

with max.

Many responder hands with a 5 card major bid better going via 2C-2D-2N rather
than the transfer:

it is the pricipal way of playing 3N rather than 4M.
