Is anyone aware of a strong club system in which 1 of a major may be opened on 3, 4, or 6+ of the opened major suit? The observed system uses 2d opener to show a 5 card major. 1nt openers are 8-11 Not Vully, 14-16 Vully, but Not Vully 7 hcp are often opened 1NT.

There is a pair playing on BBO using this system with totally remarkable success at IMP.

No, but it sounds not far from a canape system where 1M shows either 4 or 6, and with 5 you open at the two level.

Main reason I respond is to say "hi, welcome to the forum!".

There is a system I've read of called Mafia Club, which is similar.

This description is from Larssen's system summary:

The Mafia Club was invented by Kenneth L. Lindsay, 1981. Mafia stands
for Majors First Always, and the main idea of Mafia is to open
1H/S as often as possible. In principle, Mafia is a strong 1C
system, but since the openings 1H/S may be based on three cards
only, it was placed among the artificial systems. Information from
Rene Steiner, Dusseldorf, Germany.

Mafia Club Opening Bids
1C 16+ any shape, 16-19 if balanced
1D 11-15 different shapes
1H 10-15 3+ hearts, unbalanced
1S 10-15 3+ spades, unbalanced
1N 13-15 balanced
2C 16+ any 4441
20+ balanced
2D 11-14 solid 7-card minor
13-15 6M331, 6M4m21, or 6M4m30
2H 6-9 6+ hearts or
11-15 6 hearts 322 or
13-15 5 hearts 332
2S 6-9 6+ spades or
11-15 6 spades 322 or
13-15 5 spades 332
2N 6-9 6+ minor
3C 13-15 6-7 clubs, no major
3D 13-15 6-7 diamonds, no major
3N 11-14 solid 7-card major

If the openings 1H and 1S are made on 3 cards, the suit is at least as
strong as KTx.

You can find this summary on Dan Neill's website:

under "More Stuff" - it has a ton of summaries like the above.

There's also The Little Major, an old system based on 3-card majors with which Terence Reese won the 1955 Bermuda Bowl

Dunno where you can get notes of it, though. But should be quite fun to play.

re: Little Major
The following is from the book "Bridge Conventions, Finesses and Coups" by Terence Reese (pp. 98-99) 1965

Openings
1♣ = basically = hearts. Response 1♦ = usually negative, but may show some big hands. Response of 1NT = semi-positive, may be balanced, have a suit, or have hearts. 1♠, 2♣, &2♦ are positive responses.

1♦ = spades or strong, balanced hand. Response of 1♥ is negative, etc, etc.

1♥ = "either very strong or very weak. Responses based on controls."

1♠ = 12-15 with "some values in both minor suits, no biddable major"

1NT = 14-16

2♣ or 2♦ = 12-15 "one fair minor suit, no biddable major"

2♥ or 2♠ = "use major-minor 2-suiter."

2NT = "either minor suit pre-empt, or strong minor 2-suiter.


Hope this is of interest. Enjoy.
Sometimes these old books have some value.
