I've been thinking about aggressive natural systems (where the trend is to be less aggressive, using 5 card majors, unbalanced diamonds and strong NT). In Sweden 4 card majors combined with strong NT is a very popular system (at least at club level). Do you think it would be possible to play 3 card majors (and still have constructive auctions), thus increasing the aggressiveness even more? I'm thinking something like this (probably only non-vul):

1C = Natural or 15--17 bal (may have a 5 card major). Some sort of transfer responses probably.
1D = (4)5+ diamonds, unbalanced
1M = 3+ major; 12--14 balanced or natural 5+
1N = 9--11
2C = 18--20 bal or any GF
2DHS = Probably weak, or perhaps multi and some constructive bids
2N = 21--23

Over 1M I'm thinking something like:

1H---
1S = Natural
1N = Non-forcing, but forcing if opener has a 5 card major
2C = GF relayish
2D = Limit raise+ with 3+ hearts
2H = Single raise, 4+ hearts
2S+ = ?

1S---
1N = As above
2C = As above
2D = Hearts
2H = Limit raise+ with 3+ spades
2S = Single raise, 4+ spades
2N+ = ?

There were some Dutch juniors that played "trios" long time ago. You might be able to find some info about that.
We had a discussion about a similar system: http://www.bridgebas...d-major-system/
But I have almost zero experience with it. Played a couple of session with csaba but it turned out that the follow ups to the major suit openings would require some work
The world would be such a happy place, if only everyone played Acol :) --- TramTicket

Untangle these 3xM in competition.
What besides ambiguity do you pin your hopes on?

It may be so that a canapé structure (with a forcing club) is wiser if one wants to try out an idea like this. Just like dake50 says the major openings will probably be a pain in competition (just like short minors when playing 5533 or 5542).

Thank you for the link. The system idea proposed is pretty similar to Turnip Diamond (but their 1M opening promises exactly four):

1C = 15+ unbal or 17+ bal
1D = 5+ major, 8-14 (but see 2M)
1M = Exactly 4 card major, 11-14 if balanced or 8-14 with longer side suit
1N = 13-16
2m = Natural 11-15 without a 4 card major
2M = 13-16, 5+M and 4+m
2N = 13-16, 5+ diamonds and 4+ clubs
3C = Major two-suiter, 3 or 5(6) losers
3D = 6+ diamonds, 10-12

glen:
Thanks! I do not quite understand how the second pair deal with no trumps under 14-16 though.

dake50:
The reasoning would be to remove as much of the 1-level as possible, but to still have some safety. It employs a mini NT and sort of a weak NT (but opens this 1M). The main inspiration was the interview with Bocchi about his Big Bang system (becoming warriors when non-vulnerable).

how about revolving around this philosophy:

1M opener = "I have a GF raise of your 5-card 1M opening, if you happen to have one."

or perhaps this one:

1m = 4+ in the linked major
1M = 3+ in the major bid
2m = 5+, at most 2 cards in a major

well, anyway.. just some loose ideas.
