1m-2m-2m+1 is weak NT. Has anyone played this? Is it any good? Gains/Losses?

It is very reasonable to play some kind of system over inverted minors. Having a bid for weak NT's is a good start.

nmf is not inverted minors

But agree with arend, anything helps. I play exactly the opposite, 2m+1 is whatever but weak NT. Actually whatever with 14+ (GF)

Justin has a nice inverted minors structure on his blog. Not as good as what we play of course .

I've played 2m+1 as ANY minimum, and it works out ok for most hands.

Justin's discussion of 1m-2m follow-ups, which includes a summary of advantages and disadvantages, is at http://squeezingthed...arch?q=inverted

Also, look up Fred's own suggestions for a 2/1 base. I'm a bit lazy at the moment to do the search, but I have it saved on my hard drive.

I play a slightly different variant with Phil and yet another slightly different variant with Jason.

If you play strong NT and inverted raises as INV+ values, I think it's important to play some form of methods. I really hate the 'standard' approach where 2M shows a stop and 2NT is a weak NT, because i) responder cannot invite opposite a weak NT and ii) opener has not had a chance to describe their hand with the first rebid, even to the extent of whether they have natural clubs or not.

In one partnership I play 1C - 2C - 2D and 1D - 2D - 2H as 12-14 or 18-19 balanced.

1C - 2C -
....2D = balanced
....2H/2S = 5 clubs, 4 cards in bid major any range (then 2NT/3m NF others GF)
....2NT = diamonds, reversing values
....3C = min NF (either 6+ clubs or 5/4 clubs & diamonds)
....3D/H/S splinter

1C - 2C - 2D -
....2H = FG relay
....2S/3D/3H = singleton, club slam try
....2NT = nat NF opposite 12-14
....3C = nat NF

In a different partnership I play similarly, but not quite the same:
1C - 2C
.....2D = 12-14 balanced or diamonds
.....2H = hearts, reversing values
.....2S = spades, reversing values
....2NT = 18-19 bal
....3C = min NF

etc

The difference is that the second partnership always responds 1major with a 4-card major, the first can make an inverted raise with a 4-card major on the side, although if so they have game forcing values.

We play a fair bit of system, much of it from Garozzo's Ambra system. All of our notrump hands are in the 1♣ opener, so 1♦ is always unbalanced and the continuations are fairly normal (in that context).

1♣ - 2♣
2♦ = 11-13 balanced, or clubs+diamonds, or minimum with clubs
2♥ = 4+ hearts, 5+ clubs, any range
2♠ = 4+ spades, 5+ clubs, any range
2NT = 17-19 balanced
3♣ = non-minimum clubs, no shortage, FG
3X = splinter

1♣ -2♣
2♦

2♥ = relay, slam interest
2♠ = relay, game interest
2NT = natural, invitational
3♣ = natural, invitational

1♣ -2♣
2♦ - 2♥
2♠ = clubs and diamonds, non-minimum
2NT = 11-13 balanced
3♣ = minimum with clubs
3♦ = clubs and diamonds, min

1♣ -2♣
2♦ - 2♠
2NT = 11-13 balanced
3♣ = minimum with clubs
3♦ = clubs and diamonds
