An idea I got a couple of days ago while responding to the 'Multi 2d' thread:

(...)
2♦ = weak-only Multi with either 6(+)M3-OM or 5S3-H4+m (will explain the absence of 3-S5H4+m hands below)
2♥ = weak, 3-S5H4+m (Muiderberg)
2♠ = ? (but not Muiderberg)
(...)


2♦-?:

(...)
2♥ = P/C, likely 1- M or (3)4+S2H
...P = 6(+) H
...2♠ = 6(+) S
...2N = non-MAX (or if you want: MIN), 5S4+m
......3♣ = P/C
......(...)
......3♠ = to play
......(...)
...3m = MAX, 5S4+m
2♠ = P/C, likely 2S2+H or 3S(2)3+H
(...)

Some explaination is in order. It occured to me that if

2♦ = weak-only Multi with either 6(+)M3-OM or 5M3-OM4+m,

then I could think of a good way to diagnose and avoid a 5-1 or 5-0 fit in spades, but not in hearts, so it made sense to remove the 3-S5H4+m hands from Multi 2♦ and play Muiderberg 2♥. But a Multi between the two above in inclusiveness,

2♦ = weak-only Multi with either 6(+)3-OM, 5S3-H4+m or 5H5+m,

where

2♦-2♥; 2♠ = 6(+) S or 5H5+m (!)

and everything else is as above, looked (and looks) quite playable, too.


Thoughts?

You just play you pass the multi with 4+ diamonds and 0-1 in a major and opener passes with 3 if doubled.
