Modified Wilkosz Both majors or minors, or spades+minor

- ♥+m twice as frequent as ♣+♦
- with hearts you are less likely to want to play notrump so wrong-siding is less of an issue
- opps get only one cuebid (and that's 3♥ which is less versatile than 3m)
- 3♦ is available as a forcing relay
However, Wilkosz with natural 2M openings is more preemptive than Multi. So I thought, maybe we could combine the two. So 2♦ shows both majors, or both minors, or ♠+m.
Advantages:
- with 32(62), responder can bid 2♠ without having to fear a ♥+m hand. So the right fit is found when opener has both majors.
- one less hand type to untangle after the 2NT forcing relay to 2♦
- if opps double 2♦, responder passes to say "pass if you have diamonds". Maybe redouble is also nonforcing. This puts a bit more pressure on opps as the chance that opener has diamonds is now 50% instead of the 40% in normal Wilkosz.
Of course, it is a disadvantage that we can't play 2♥ when opener has ♥+m while we still have to be at the 3-level when opener has minors (although we don't prevent opps from bidding 2M when we have both minors).
Any thoughts?

He can only further the 2D preempt holding both spades and one or both minors. Particularly for 2D, you may seldom be able to jack the bidding up very high.

2♦ = Wilkosz
2M = Weak 2M
is more preemptive than
2♦ = Multi (incl. all Weak 2M type hands)
2M = 5+M5+O (= all Wilkosz type hands),
Yes that's what I mean.

Yes, it might be better to play 2♦ as spades+other. And forget about the both minors hands.

For original wilcosz, if opponents fit in a major, you'll know that partner holds the other major which is not the case here.
e.g. 2D-(3H)-?

2♦ shows both majors, ♠+m or single suited clubs.
Then you can untangle with 2D-2H as pass or correct. Correcting to 2S is spades + minor and 3C is clubs. Full Opening Structure
2C: Weak Clubs hands
2D: 2♦ shows both majors, ♠+m or single suited clubs.
2H: Hearts
2S: Spades
2NT: Hearts plus minor
3C: Both clubs
2NT relay would be:
3C: Clubs
3D: Diamonds and spades
3H: Both majors
3S: Spades and Clubs
Not sure this is good, you lose a bunch of pre-emptive action from your 3C openers. I don't love Wilkosz

sfi and I have been playing "normal" Wilkosz for three years and our experience is as awm suggests: it's hard for responder to preempt effectively unless he has both majors or a three-suited hand. The ambiguity about which two suits opener holds also affects us in constructive and competitive auctions. However, our assessment is that it is harder for the opponents to deal with Wilkosz and weak twos than a Multi 2♦ and 2♥ and 2♠ showing that major and a minor, or (as is surprisingly frequent in Australia) 2♥ showing hearts and another. We think that's true even though opponents are used to dealing with multi-meaning openings, so it's a not (at least not substantially) a lack of familiarity.

Since you're not restricted by the WBF systems policy, how about
2♦ = 5M5+m
2♥ = Major Flash
amd either
2♠ = 5+S5+H (=> 2N = INV+ relay)
2N = 5+D5+C (=> 3♥ = GF relay)
or
2♠ = 5+D5+C (=> 2N = INV+ relay)
2N = 5+S5+H (=> 3♣ = INV+ relay))
?

I feel like Wilkosz is 'obviously' good because it's a very well defined opening for hands that are well suited to pre-emption (and the auction + your holding usually removes all ambiguity about what hands people hold where it is nessecary for the partner of the Wilkosz guy to do something at a high level), so it's going to rake it in when it comes up IMP wise.
My only concern is that the frequency isn't high enough, but checking the frequency tables says it's 2%, which is higher than I thought it was going to be!
