The meaning of inverted minors is that the weaker raise is 3m and the stronger raise is 2m. I have to say that if you play inverted minors off by a passed hand or inverted minors off in competition, then the weaker bid is 2m and the stronger bid is 3m. The reason being if inverted minors are off, well then, the stronger bid is the jump raise by definition.

2m is 6-10/bad 11 where 6-8 promise 4 cards only.
3m is preemptive, extra length with 8 or fewer HCP.
Q-bid shows 11+ LR.
No, a simple raise of ♣ does not promise 5, just 4. 83% of the time partner has 4 or more, right?
Trust demands integrity, balance and collaboration.

Cue bid of what suit? This is an unopposed auction.

We play 'on' by a passed hand but 'off' in competition. We used to play them on in competition as well and used the cue bid as 11-12 HCP without a stopper but found it was much more useful just to be able to raise partner's suit (would you believe!) They should certainly be off after a double anyway.

From my experience, using 2NT as the raise after being a passed hand runs the risk of wrong-siding the strongly potential 3NT contract. So the 2nt response as a raise should be used only when a potential 3NT contract would most likely be "right-sided".

We play this by unpassed hands too so that our inverted raise is a game force.

Some people use it as 0-4 with 5 of the suit opened, unlikely you want to be in 3N and working better with a weak NT I think so partner either has extra values or extra shape.

Actually, crisscross would lose a lot for us. 2D/1C and 3C/1D are useful bids for many pairs as natural with the agreed strength, reverse flannery, or whatever.

Criss-cross: with some partners I play this as 8-10, and the inverted raise as 11+. With these partners is makes sense to have the criss-cross raise be on, and the inverted raise be off, by a passed hand. In this case my immediate single raise is 6-9 and usually exactly 4 cards.
1C-2D can certainly be a useful sequence. There are alternatives, like using 2S or 2NT to show the "1D-3C" hand, to free up 2D.

I should have had a better title... maybe:
Inverted Minor Raises : On or Off ?
EDIT: And, yes, I was particularly interested in the "passed hand" situation . Criss-cross "ON" certainly helps the situation: thus, it could go:
p - 1C
2C = constuctive
2D! = limit
3C = preemptive
My main concern is that 3m should remain preemtive.

I have never seen this construction. If we have a weak hand with a five card fit and both opponents have passed, it's short odds that partner is strong balanced. The chances of him having an unbalanced natural opener are very low indeed.

This is quite true. It is also an argument for responder as a passed hand to have as many bids to naturally describe his/her size and shape as possible. The patterns we give up in order to use crisscross become more costly and more frequent. There is no real need to make an inverted raise an absolute game force and/or include 4-card majors in the mix.

It's much more likely that pard has 3-4 clubs with enough strength to shut the opps up. But showing club length and range while denying a 4-card major (ALWAYS for us) can set pard up to do the right thing, especially over a simple raise where they can investigate notrump without committing. Maybe blast 3nt over 3 clubs with a source of tricks in sight.
Yeah you lose some things I haven't thought of but over 1♣ we try to recover them with a 1♦ bid instead of two and a 3♣ bid over 1♦ against silent opps looks like we are pre-empting ourselves.
So what are the benefits of using these bids to show something else?
What is baby oil made of?

Well, there is certainly no need to make an inverted raise an absolute game force by a passed hand. This would free up the "criss-cross" bids, if used, for fit showing or something else.

Many people (myself included) don't even make the inverted raise game forcing by unpassed hands. We play it as invitational or better, so it's a one-round force.
And by a passed hand, it's merely invitational, so it's not even forcing.
