Please DavidKok,
- Would you explain how Gazilli works after 1♦ - 1M?
- Do you also play it after 1♣ - 1M?
I don't actually play Gazzilli after 1
♦-1M, on the grounds that my system is already more than sufficiently complicated. I'm convinced it is very good with an unbalanced diamond (which is what I play) though. My source is
Yuan Shen's article, where 1
♦-1M; 1NT* shows either 16+ any or 11-15 with 6(+) diamonds, and any other bid denies reverse strength (so 2
♣ is 11-15 with 5-4 minors, partnership preference if it shows exactly 5(+)=4(+) or also contains 4=5, and 2
♦ shows 11-15 with exactly 4 hearts!).
Of course this particular hand is still troublesome, my comment was slightly tongue-in-cheek. But since you can now systematically distinguish between 11-15 with exactly 4 hearts, by bidding 1
♦-1
♠; 2
♦, and 16+ ('sound reverse') with hearts by bidding 1
♦-1
♠; 1NT*-2
♣; 2
♥ you are in a much better spot than many other players would be. I would strongly consider downgrading this particular hand to 15 or so and rebidding 2
♦, showing the heart suit.
Something to keep in mind here is that since the 1
♦ in this system is 'unbalanced', the 1NT is not needed as a natural rebid. I currently play this rebid as 11-15, exactly 4=5 in the minors (which we do not open 1
♣ based on some probabilistic argument), and frankly it is far from ideal. We even considered leaving the sequence meaningless!
I don't see any reason to play something like this over 1
♣-1M. For starters both the 1NT and 2
♣ rebids are extremely useful as natural bids, and after partner 'accepts' the Gazzilli bid by making the cheapest call available it is too late to stop in your long suit. Also, I have no idea how it would work.

I rank
1. 2♦ = NAT underbid
2. 1N = NAT underbid. Might result in playing a 5-1 ♠ fit (not all that bad).
3. 2♥ = NAT but an exaggeration.
4. Open 1N. But partner is likely to transfer.
5. 2♣ = NAT but might lose a 4-4 ♥ fit -- Partner can introduce 2♥ over 1 or 2.
