If you had to design an opening structure for a system where non of the bids (except pass) at the one or two level could be "weak", what would the system look like? Let's say all opening bids below 3♣ has to show at least, I don't know, perhaps 10 hcp?

Fantunes

[NickRW]

1x 4 or 5 card majors according to choice
1NT weak or strong according to choice
2C Traditional
2M Acol 2
2NT 20-21bal
2D Strong only multi, say 22-23bal or Acol 2 in either minor

[spotlight7]

Churchill Natural

4 card majors. 12-14 1NT. No strong forcing opening.

1NT* reply to one of a suit HCP @4+HCP and often less with

a 6 card suit or 5 card support for the opening bid.

One over one bid was @8+HCP

Yes there's several existing (or former) systems having this approach. Strong two bids perhaps being the most well known. I was thinking more in the line of new system ideas, but old ideas are fine too Ken Rexford's MICS system doesn't include weak bids:

1C = Strong
1D = 4+D, canapé style, or 6+C single-suited.
1M = 4+M, canapé style, or 5M332.
1NT = 12-15
2C = Three-suited.
2D = Both minors, 13-15
2M = Roman (5+M and 4+C)
2NT = Both minors, 10-12

Or why not a "balanced diamond", to counter the modern trend of unbalanced diamond openings?

1C = Strong
1D = 11-13 NT
1M = 5+M
1NT = 14-16 NT
2m = 6+m or 5-4 minors.
2M = 4M and 5+m.
2NT = 5-5 minors.

Fantunes

I prefer to have 5 (predominantly) weak 2-level openings instead of 0, but instead of Fantunes, maybe

1♣ = "10+, NAT unBAL" or "11-13/17-19/26+ BAL" [what I (= nullve-nullve) play now]
1♦ = "10+, NAT unBAL" or "20-22 BAL" [what I play now]
1M = "13+, 5+ M, unBAL" [what I play now now, but with "13+" replacing "10-21"]
1N = "14-16 BAL" [what I play now]
2x = "10-12", Multilandy guaranteeing 5+ M
2N = "23-25 BAL" [the strong option in what I play now]
other = normal,

which avoids most of the problems Fantunes has on unBAL "10-12" hands.

It's a funny question for me because it's exactly about the system which I created some years ago and continue playing it now.

1♣ = 12-15 balanced (including any 5332) / 12-15 unbalanced with clubs / 12-15 3-suited without diamonds
1♦ = 12-15 4+♦ unbalanced without 5-card majors
1♥ = 16-21 4+♥
1♠ = 16-21 4+♠
1NT = 16-21 balanced without 4-card majors
2♣ = 16-21 unbalanced 4+♣ without 4-card majors
2♦ = 16-21 6+♦ without another 4-card suits / 22-24 balanced
2♥ = 10-15 5+♥ unbalanced
2♠ = 10-15 5+♠ unbalanced
2NT = GF (22+ unbalanced / 25+ balanced)

[Kungsgeten]

Strong diamond idea:

1C = Club canapé style or 11-13 NT. Not both minors.
1D = Strong.
1M = Canapé style.
1NT = 14-16
2C = Minors
2D = Natural single-suiter
2M = 5M and 4+D.
2NT = Strong?

[straube]

I’d just try to fit to what I presently like. Maybe...

2D-10-15 6D, not 4H
2M-natural (6-7cd) and 10-12/13
2N-10-15 6D/4H

You could be boring and do polish club with a 14-16 NT and a Mexican 2D and flannery. 2S is akward. Playing it as 10-12 with 6 spades probably makes life easier.

Now all your constructive auctions are super clean as you've taken all the balanced options except 11-13 out of 1C and you have great definition on your 1H opener.

Not sure which would bid Polish would benefit more from; Flannery or "Precision 2D".

1C = 12-14 NT or 15+ clubs or (17)18+ unbal or 22+ NT
1D = Nat unbal, 11-17
1M = 5+ major, 11-17
1NT = 15-17
2C = 6+C or 1-4-3-5 (if 2-4-2-5 is treated as balanced), 10-14.
2D = 18-19 NT
2H = 4-4-1-4 or 4-4-0-5, 11-16; or 3-4-1-5 11-14.
2S = 10-14, 4S and 5C.
2NT = 20-21
