A discussion in another thread makes clear that at least some readers are playing inverted minors much weaker and much more preemptively than I now do. For ex, I think that after 1 - P, some of you would bid 3 with, say, xx, xxx, xx, Jxxxxxx. Is that about right?

If so, 2 questions. On the same auction, how do you handle something like Qx, xxx, Kx, Qxxxxx? I guess you bid 1nt? How does that work in practice?

2d question, what is the best hand you could hold for this very weak inverted raise?

thx, B)

Yep, those are the right questions which "super weak" style players have to answer. They must overload other bids, such as 1NT to gain the preemption. We stick with showing a minimum response for that reason (stopping short of a limit raise). And we lose some preemptive value. It is truly a choice --no right or wrong.

You should have 3 ways to raise, weak (defined as partner should pass with 18-19 bal), constructive (defined as partner should bid 3N with 18-19 bal), and limit+

If you are only using the direct raise and the jump raise as ways to raise the minor, then you have 2 bids to show 3 hand types. You can then choose to define 3m however you want, including wide ranging incorporating both weak and constructive, but at the end of the day whatever you choose will always be flawed because you have too many hand types to show in too few bids.

FWIW if playing this way, I like to play vul that the jump raise is constructive like 6-9, and 0-5 either passes or bids 1N. I like to play that NV the jump is weak like 0-5, and the constructive bids 1N. I think most people tend to just have a very wide range for 3m and hope for the best. Of course, I hate playing a system like this and would much rather dedicate a 3rd bid for sorting this out.

I have seen:

1m-2m: GF
1m-jump in om: inv.
1m-3m: preemptive.

I don't know how well this works in practice.

It works OK, except that the upper range of the non-invitational hand is still too high. So one winds up bidding 1NT with the constructive but not invitational hand, and reserves the double raise to those hands that are purely preemptive.

I play a 2NT response as weak, defined as a hand too weak to play 3NT opposite a strong balanced opener. That way it doesn't wrong-side. Then 3m is constuctive and 2m is limit+.

The problem comes in a 2/1 system of how to show a balanced 11-12 (if you can't respond 2C to 1D).

You can play a immediate jump raise as pure preemptive. a simple raise as gf.
1C 2D is inv. 1C 2S as constructive raise.

This is my usual style (very wide 3m range) when playing inverted minors. I'll admit that sometimes you get to a very bad 3n (partner basically always bids 3n with 18-19), but I hate the less preemptive and less descriptive 1n on 5 or 6 card support more.

How about 1C - 2H as a slam try :(

That is my agreement as well - 1 of a minor, 2 spades is a 5+ card raise of the minor, less than invitational values, but something that should have decent play for game opposite an 18-19 NT hand. 1 of a minor jump raised to 3 is purely preemptive and to play unless you have some sort of distributional monster.

Not sure which statement you think is silly.

Only a little over 1% of hands are 1 counts so to not bid on them is not so silly IMHO.

The frequencies are such that a 4-7 HCP range is more frequent than 0-6 HCP.

So you do not actually give up that much by omitting the very weak hands from your range.

I like...

1C-2C=simple raise (rarely with four good trump)
1C-2D=invitational+ raise
1C-3C=weak raise (not convertible to 3N opposite 18-19)

then

1C-1N is positional for NT

I use 1C-2M for Reverse Flannery but admit it isn't really necessary. One really has too much room over a natural 1C opening.

I like

1D-2C=not game-forcing
1D-2D=LR+
1D-2M=Reverse Flannery (think this is very necessary)
1D-3C=simple raise
1D-3D=weak

Like Justin said, you must have three ways to raise.
And like he said, your limits should focus on the fact what partner will do with the strong NT hand.
So if your 1 Club hand contains 18-19 NT hands, I would like:

1 Club 2 Club inf+
1 Club 2 Diamond 7-9
1 Club 3 Club ?-6

I would never bid 3 club with a 1 HCP 2335 hand- but a one point 2326 hand maybe be bid this way.
Kind Regards

If you play the jump raise as very weak, partner knows to pass with 18-19 balanced. If you play it constructive, partner can bid 3NT with those hands. If you use 4-7, partner has a problem. The fact that partner has a problem more frequently does not make it a better bid.
and the result can be plotted on a graph.

I play:
2m = 10+
2 = 6-9 (opener can ask with 2NT)
3m = 0-5 (opener should pass with 18-19 balanced)

Works very well imo.

If you mean 2 as a two way, weak or GF, response, looks to me like that's SuperChart.

Why bid 1C-2D with 7-9 and 1C-2C with inv+ ?

Why not 1C-2C with 7-9 and 1C-2D with inv+ ?

1C-2C lets you play 2C. Granted, the opponents are likely to balance, but it gives opener the option to defend or bid 3C.

1C-2D leaves lots of room for us and opponents while depriving us of playing 2C.

Gaining an extra step when you are inv+ can be quite useful (especially if you use the step well and don't just play some stopper showing bids), and playing 2C is a narrow target that is pretty rare.
