A Kantar Two Clubs


This convention assumes OPENER opens 1/1/1, RESPONDER responds 1 of a suit, and OPENER rebids 1NT to show a balanced hand with 12 to 14 HCP.

OPENER's 1N rebid denied 4 card support for RESPONDER's suit,
but may include 3 card support or 4 of the other major*.

 RESPONDER rebids 2 to ask about the MAJORS (&).
Opener LHO Responder RHO
1 Pass 1 Pass
1NT Pass 2?  

    

 


What kind of hand would RESPONDER have for a Kantar 2 bid?
RESPONDER should be looking for an 8 card major fit and have:
a)
5 of the first suit (spades in the example above) or
b) 4 of the unbid major (hearts in the example above) or
c)
both (4 hearts and 5 spades in the example above)

Responder must have at least an invitational (10+ points) to bid Kantar 2.
Here are some RESPONDER hands that respond 1 and then rebid 2, looking for an 8 card major fit:
AQT85 JT5 T43 A2 : looking for 3 card spade support
AQT85 JT54 T2 A2 : looking for either  3 card spade support or  4 card heart support

OPENER simply shows support, if any, by bidding the supporting suit. Otherwise OPENER bids 2:

Opener LHO Responder RHO
1 Pass 1 Pass
1NT Pass 2 Pass

2 denies 4 hearts & denies 3 spades
AK K43 K43 J8765

2 shows 4 hearts
AK K654 K43 J874

2 shows 3 spades
AK3 K32 K43 J654

     


 

 

 

 

 

 



After Responder's original 1 bid:

Opener LHO Responder RHO
1 Pass 1 Pass
1NT Pass 2 Pass

2 denies 3 hearts & denies 4 spades
AK3 K2 K43 J8765

2 shows 3 hearts
AK K43 K43 J8765

2 shows 4 spades*
AK54 K2 K43 J654

     


 

 

 

 

 

 

 

*Some partnerships may allow OPENER to rebid 1N with an undisclosed 4 card major(s).

Responders invitational (10-11) rebids:
With a fit, responder raises the suit to the 3 level .
Without a fit, responder rebids 2N.


Another Variation:

Many partnerships play
Opener LHO Responder RHO
1 Pass 1 Pass
1NT Pass 2, to play, 5 spades and 4/5 hearts


 

 

and opener, with 2 spades and 3 hearts wishes to play in:
2 if responder has only 4 hearts
2 if responder has 5 hearts

Consider the Kantar 2 auction:
Opener LHO Responder RHO
1 Pass 1 Pass
1NT Pass 2 Pass

2 denies 4hearts & denies 3 spades
K3 AK2 K43 J8765

Pass 2, 5 hearts:
forcing? invite?to play?

 

 

 

 

If Kantar 2 is at least invitational, 2 is at least invitational.
The choices are yours.
