"Jacoby 2NT" and Precision

[keylime]

We don't even use 2NT as a GF raise - we use that as a natural, forcing bid promising a balanced hand. What we do instead is cheapest jump shift into a suit as GF with the following as responses:

 

1H-2S:

 

2NT - balanced, 5-3-3-2

3C - any minimum

3D - maximum hand with shortage

3H - maximum, balanced, five trumps

3S - unused

3NT - 6-3-2-2 or 7-2-2-2

4C/D - 4 card suit with A/K

4H - drop dead signoff

 

1S-3C:

 

3D - any minimum (including 5-3-3-2 hands)

3H - max hand with shortage

3S - max hand, balanced, five trumps

3NT - 6-3-2-2 or 7-2-2-2

4C/D/H - 4 card suit with A/K

4S - drop dead signoff

 

This has worked wonders - lot easier to cope with than Romex Raises due to the ease of use.

There is a lot of redundacy in these responses, Dawyne. I am sure you can optimise them to greater effect.

 

Just one example:

1H-2S:

 

2NT - balanced, 5-3-3-2

3H - maximum, balanced, five trumps

 

These 2 responses are similar and can easliy be multi plexed.

Yes there is, realize it's only 6 weeks old and is getting more refinements, but we liked Fred's concept so much, but didn't want to part with the Martel-Stansby notions....call it a prototype. It'll get better - it's KLP, it HAS to be better!

This is a common 2NT-structure in Sweden:

 

3♣ minimum (no void)

3♦ max, no shortness

3♥ max, singleton/void ♣

3♠ max, singleton/void ♦

3NT max, singleton/void other major

4X void X with min or supermax

 

1M - 2NT; 3♣ - 3♦ slaminterest, asking for shortness

3M no shortness but and some interest

3OM singleton

3NT no shortness, interest of playing 3NT

4m singleton m

4M bad cards

 

1M - 2NT; 3♦ -

3M start cuebidding pd

3OM singleton in OM

3NT interest of playing 3NT

4m singleton m

4M bad cards
