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.

I played unbalanced 11 to 22, or balanced 8 to 10, for a few years. It was very fun and worked rather well.

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.

American Forcing Minor used a 1♦ opener which was either a 15-17 NT, or 15-20 HCP and the beginning of a possible canape sequence.

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.

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)
