Suppose you are playing that 2m shows 11-15 HCP, an unbalanced hand, and no 4-card major. I.e. you are either 1-suited in a minor (6+ long; other suits shorter than 4) or 2-suited with both minors (5+/4+).

What responses do you recommend?

What do you do with 5-5 in the minors? Do you open 2C or 2D? Do you use 2NT for minimum hands and 2m with better than minimum?

Angelina-Sementa's WBF convention card gives this as their response scheme

Over 2C:
2D = Relay
2M = Not forcing
2N = limit raise of clubs
3C = weak
3D = 5+ hearts and 5+ spades. Invitational or better.
3M = weak
3N = To play

Over the 2D relay:
2M = Minimum with 3 cards in bid suit and 4 diamonds
2N = Maximum with 4 diamonds
3C = 6+ clubs
3D = 6 clubs, 4 diamonds, maximum


Over 2D:
2M = Not forcing
2N = Relay
3C = 5+ hearts and 5+ spades. Invitational or better.
3D/3H/3S = Weak
3N = To play

Over 2N:
3C = 4+, minimum
3D = 6+
3M = 3-cards in bid major, 4 clubs, maximum

It feels like better schemes must exist. Perhaps:
- Make 2M forcing one round?
- Over 2D, make 2H a relay and 2N = 5+ hearts, forcing one round?

But I don't have any experience to judge what's important and what's not.

Thanks for any help you can provide.

I like 2M response as 5-suit or stop. Opener rebids to show other oM-stop, 3-fit. Else rebids 6-suit quits.
Why effort to play 2M when the very reason to open 2m is get above opponent's Major? Counter-intent at best, often silly. "I don't have Major interest" "But, I do and I'm boss!"

I agree with awm that 2M should be forcing, since if opener has a small singleton they need to guess what to do - if CHO has 5 cards, it's probably a worse contract than 3m and if GOP has 6 cards, it's probably the best contract.

Hi, i play 2C-2D Relay, 2H/S 8-11 5+NF, 2NT nat INV, 3C PRE, 3DHS inv good suit
Over 2D rel: 2H 4diam->2S FG relay, 3C/D=INV, 3H/S=6+FG
2c-2d-2h-2s: 2NT=min->3C asks: 3d=6c/4d, 3H/S=3card, 3NT=5422, with max over 2s bid natural your shape
2C-2D-3C=min 6+clubs
2C-2D-2S=max 6+clubs with any singleton->2NT asks singleton
2C-2D-2NT=6+C balanced
Similar over 2D, but here we play 2H F1 Relay and 2NT as 8-11 5+H and with 55 minors we always open 2D and after 2H with min we bid 3C and with max 55 we bid 3H/S with spl, cheers:)
