Henri Schweizer the very intelligent and pleasant BBO yellow had some discussion several years ago in this Forum The basic was to use 2M openings to be twosuiters 5M+4-5C 12-15 hcp.This will avoid double meanings of Gazzilli 2C after 1M - 1NT.There is also a Swedish version using 1M -1NT > 2M to show the same and the 1M - 1NT > 2C -2M bid to show 14-16 and a sixcarder.This assumes a 10-13 two opening with 6 M´s.
Now my idea is very simple. Use the above "copy" of Riton2C, a 2M opening to be 5M+4-5D and a Multi 2D to be either major 10-13 and a sixcrder.This results in 1M - 1NT > 2D is a strong hand some 15-17 hcp depending on your Gazzilli limit.I think it would be great to have also a 2D rebid to be strong. That would simplfy the whole rebid structure. No need to jump with understrength hands for instance. Comments are welcome.

I am not sure I fully understand, but if 2M shows diamonds and 1M 1NT 2D shows a strong hand (while 1M 1NT 2C is weak), how is this better than Riton? It seems to me there is more room over a strong 2♣ to clarify hands than over a strong 2♦.

[Kungsgeten]

I'm not sure, but I think OP means:

2D = 10-13 with 6 card major
2M = 5 card major and 4-5 diamonds, 11--14

Then after a major opening:

1S--1NT;
2C = 14+ with 6+ spades or any 18+
2D = Any 15--17, except 6+ spades
2H = 11--14, natural
2S = 11--14, 4--5 clubs

I think it would work better if 15--17 was included in 2C though, so:

1S--1NT;
2C = 14--17 with 6+ spades or any 15--17
2D = Any unbalanced GF (so about 18+)
2HS = As above

I also think it would be better (or at least cooler) if the 2M opening showed 10--13 and 2D showed 4--5 diamonds and a 5 card major. This way responder can pass the 2D opening more often.

Look at Kungsgeten - he has nderstood. The point I try to make is 2M = 5-4 in M/D and 1M - 1NT > 2M shows 5-4 in M/C. Voila!You then need an opening 2D for 10-13 and six cards in spades or hearts. In the normal Gazzilli sequence 1M - 1NT > 2C the 2S bid now shows 14-16 and a sixcarder.Again this means that the sequence 1M - 1NT > 2D shows a GOOD hand - say 16+.

Nice proposal to let 2D show diamonds and a fivecard major! How to use 2D as any unbalanced is very interesting and a subject very well worth to discuss further.Any proposals? I´m not sure about integrating 15-17 balanced - seems to belong under normal opening bids first or second round.

[Kungsgeten]

Yes, the 15--17 should be 15--17 unbalanced. Perhaps something like this (where 2C is 15--17 and 2D is GF)?

1H--1S; 2D---
2H = Waiting
...2S = 3 card support
...2N = 4 card minor
...3m = 5-5
...3H = 6+ hearts
2S = Natural
2N = 4 spades and a longer minor
3m = 5-5
3H = Negative, does not have the normal values for a 1S call

1H--1NT; 2D---
2H = Waiting, the normal bid
...2S = Perhaps 6+ hearts (since opener could reverse over 1H--1NT)
...2N = 4 card minor
...3m = 5-5
2S = ??
2N = Minors
3m = Natural
3H = Negative

1S--1NT; 2D---
2H = Waiting
...2S = 6+ spades
...2N = 4 card side suit
...3m = 5-5
...3H = 5-5
2S = Negative
2N = Minors
3m = Natural
3H = Natural
3S = Hearts and clubs?
3N = Hearts and diamonds?

[snillrik13]

Yes Kungsgeten you seem to have understood the basic idea very well. I try to summarize to make it easier for new visitors to understand.

2D opening = weak 11-14 hcp, 4-5 diamonds and 5 spades or 5 hearts.
2H or 2S = 6-cards in the major, 10-13 hcp

1H or 1S - 1NT > 2C normal Gazzilli but if followed by 2D waiting > 2S = 14-16 hcp and six cards in spades.
1H or 1S - 1NT > 2S now is weak 11-14 and 5M4C

1H or 1S - 1NT > 2D is NEW, strong Gazzilli 18+ (or even 19-20+?) and almost GF if 1NT response was normal.

There are two Gazzilli ways to show the opener´s hand now ( but don´t forget direct bids after 1NT response).Surely this basic approach is superior and will make life easeier.This is especially valid if you play 1H or 1S oprning forcing one round.

After 1H - 1S it is more intricate as responder is unlimited. Maybe opener should use transfers instead of Gazzilli?

Also I miss 5332 balanced hands with a fivecard major. I am a beleiver of a natural opening and not a NT opening with these hands.

Your system might show a gain once in a while, but in the meantime you've lost a lot of swings when your opponents have sailed into the right contact whilst your teammates have been 'fixed' by a Weak Two opening bid.
