Unlimited nebulous diamond


Recommended Posts

Can you explain what you mean by "short diamond" in this context where you also say 4+?

I play that a 1 open is defined as having a singleton or void outside diamonds, or 6+ diamonds, 11/12 to 22, no 5 card major. It is always 3+, most usually 4+. A 3-suiter will have max 20.

Yes I should have been clearer. I was thinking about a 1D bid which shows one of these:

 

a) Any 12--14 NT, so could have 2 diamonds

b) Unbalanced 4+ diamonds, 11--20

 

I'm curious about this in a big club context, and in that case 1D would show:

 

a) Any 12--14 NT

b) 12--14 4-4-1-4 (so 1D may have only one diamond if 12--14)

c) Unbalanced 4+ diamonds, 11--20

d) 5 clubs and 4 diamonds, 11--14

If 1D is nebulous and limited, responder can easily preempt opposite without interfering with a strong hand.

 

If 1D is natural and limited, responder may raise or easily preempt opposite it.

 

If 1D is natural and wide-ranging (12-20?), responder may raise and there is less pressure on the strong club

 

With this 1D, there is less pressure on the strong club.

 

I don't think there's that much advantage to this opening.

That's hardly nebulous, it's just a 2-way .

 

I know a few pairs playing something similar (also with 1 being 2-way) in a natural system, and this works ok for them because it solves their NT ladder when playing 1NT as 9-11. So I was expecting this to be in a natural system. In a Polish type of system it's useful to make the 1 range bigger because the 1 opening is overloaded (and 2 rebid is used for all sorts of strong hands), but in a strong context I don't see much upside.

Google "The Diamond Major" by Peter Oakley. I play a version of his creation in two Precision Partnerships. 1 is 10-14 hcp and promises at least one 4-card major. It may be as short as zero diamonds. Open 2 with 6 or 5 and 4. Use 2NT opening as 10-14 hcp and 5-5 in the minors. Full notes available via e-mail.

Have you thought about or seen a "short diamond" opening, similar to precision, but with a wide range? Let's say something like 12-14 NT or 11-20 with 4+ diamonds.
The Nottingham version that Liz McGowan and I played featured a "loose ", which we defined as...

  • Flattish 10-12 OR
  • 3-suiter (any 4441/5440) 10-34 HCP

(In Nottingham , you open 2 of a suit with good shapely hand)
