Strong 4441s were one thing that could be included in a multi 2♦, we did that when we played it.

Roman 2♦ was strong 4441/5440 with mini roman being less strong.

A couple of pairs in my club put strong(ish) 4441 through Multi: I don't remember it reaching a better contract than the rest of the field. Mikeh was fairly scathing about this agreement IIRC.

You need to play it strong enough in the multi, playing it 16+ is bad, playing it 18+ is better but obviously much rarer. It goes well with a system where big 4441s are a hole in the rest of your system which we had (art 2N rebid which guaranteed 5 in the suit opened).

I prefer strong 4441 to strong 2 minor in a multi. I'm with Sally Horton (as she then was, now Brock), who said something to the effect that they played strong 2 in a minor, most of the time reached the wrong place without either her or Sandra Landy making a bad bid, so they switched it out for the 4441.

That was my though too, I've seen them play it with strong NT range hands where they are forcing the bidding dangerously high (and might well be ok opening 1NT anyway given that our regulations allow this).

I've never encountered strong 2 minor in a multi, and this in a country where multi is almost standard. Doesn't sound like a great idea.

The standard multi for a long time here was weak 2M, Acol 2 in a minor, strong balanced, played alongside Acol 2s in the majors.

A Multi 2♦ that includes GF hands with diamonds has been played at the top level for a long time.

Convention cards from this year's Bermuda Bowl:

Caspersen - Graversen (Denmark)
Hult - Bertheau (Sweden)
Wrang - Nyström (Sweden)

One thing I like about this Multi is that it allows the following symmetry:

2♣-2♦
2♥-2♠
3♣+ = GF with primary hearts, unbalanced

2♣-2♦
2♠-2N
3♣+ = GF with primary spades, unbalanced

2♣-2♦
3♣+ = GF with primary clubs, unbalanced

2♦-2♥
3♣+ = GF with primary diamonds, unbalanced
