1MA - 1N (semi-forcing)

[Schultz112]

We need some help and advice as how to continue after 1MA - 1N (semi-forcing).

We play a Club-system where 1MA openings are 5+crd and 10-14hcp.

 

For the moment, we think something as described below - but we are open for suggestions.

 

1♠ - 1N

?

P: bal/semi-bal, min.

2♣: 3+crd.

2♦: 3+crd.

2♥: 4+♥

2♠: 6+♠, min

2N:Transfer to 3♣ (with 5+♥ or 6+♦ responder bids his suit). After 3♣:

• 
   
  
• 3♦: 6-4, max
  
• 3♥: 6-4, max
  
• 3♠: 6♠+4♣, max
   
  

3♣/3♦/3♥: 5-5, max

3♠: 6+♠, max

 

 

 

1♥ - 1N

?

P: bal/semi-bal, min

2♣: 3+♣

2♦: 3+♦

2♥: 6+♥, min

2♠: 6-4, max

2N: Transfer to 3♣ (responder bids 3♦ with 6+♦). After 3♣:

• 
   
  
• 3♦: 6-4, max
  
• 3♥: 6♥+4♣, max
   
  

3♣/3♦: 5-5, max

3♥: 6+♥, max

Do you really want to play at the 3 level with 13-14 hcp and 6-4/5-5 with no guarantee of even a partial fit?

 

I would reserve 3-level for 6-5 max..

 

Then with 5-5 make a 2-level bid then if partner rebids 2 of your major, raises your 2nd suit or bids 2N then show that you have a side 5 and a max

[Schultz112]

Can anyone help with a link where I can see a full schema?

I think steve is right. Something like...

 

1S-1N...

 

P-bal min

2C-4+C (3C if very max)

2D-4D

2H-4H

2S-6S-should promise a point or 2 more than minimum

2N-6S/5m

.....2C-pass or correct

.....2D-asks minor

..........2H-clubs

..........2S-diamonds

3C-5S/6C

3D-5S/6D

3H-6S/5H

3S-7S max

 

If you are 5/5 max, you could agree that after a preference auction such as 1S-1N, 2C-2S, 2N shows this 5/5 max and this prevents you from insisting on

play in your suits at the 3-level. If you had a wider range (say 9-15) for your opening, you might not be able to promise a 5/5 with this 2N rebid (it being needed to serve various 5422 and 5431 maximums as well) but you still wouldn't rebid your lower 5-cd suit at the 3-level (you would rebid 2N). Instead

1S-1N, 2C-2S, 3C ought to show a non-maximum 5S/6C hand (assuming this hand type is possible in your method)

 

For 1H-1N

 

2C-4+C (3C if max bal)

.....2S-should be a light invitation of clubs or alternately a light invitation of clubs or with an independent diamond suit

..........2N-max 5H3C32

...............P-light invitation with 4C

...............3C-5C

...............3D-6D around 11-12 hcps (if allowed)

.....3C-a regular invitation with 4+ clubs

.....3D-6D and around 13-14 hcps

2D-4+D

.....similar to 2C

.....2S-forces 2N

..........2N-forced

...............3C-6C and around 11-12 hcps

...............3D-4D and around 11-12 hcps

2S-5S/6H arguably forcing for 1-rd

2N-6H/5m max

.....3C-p/c

.....3D-asks minor

3C-5H/6C max

3D-5H/6D max

3H-7H max

 

Some switch their 2N and 3m rebids such that 2N promises a 5M/6m max and 3m promises a 6M/5m max.

We use Oliver's Forcing NT responses over 1H or 1S and like it a lot once you understand and get comfortable with all the asking bids...the 1NT response is unlimited in strength....Hopefully the above link works
