Also does it mean you automatically bid 2S with 3-5-(2-3) ?

Yes. The version I played used 2D as a 3-card spade raise so you could still get to 2H.

I always thought those are unplayable at matchpoints because you end up in 4-3 minor fit instead 1NT on many sequences. Am I missing something here ? Also does it mean you automatically bid 2S with 3-5-(2-3) ?

I don't often play matchpoints, but I was worried a little bit about not being able to stop in 1NT. This morning I dealt 50 hands starting with 1H - 1S to compare the auctions with standard auctions. 2D in a 4-3 didn't come up, but we got to 2H twice where a standard auction would stop in 1NT. It often isn't so clear whether 2H in a 5-2 is better or worse.

1H - 1S - 2S on a 3-5-(32) came up twice as well. I think that this is not so good.

I like how the methods avoid the dreadful 1H - 1S - 2D - 3C fourth suit, and how it deals with opener holding 6+ hearts. 1H - 1S - 2C as 11-15 is also quite nice if you are used to standard bidding.

I seem to remember 5H332 weak NTs are something like 10.5% of 1H openings. Many of those will reach the same game/2H/2S contract. Some of them will score better in 2M. I guess all edges are quite small, so just losing on a net 1% of hands on this start might well be significant; However, I don't think reserving the cheapest call for a relatively infrequent handtype is best.

If 10.5% is relatively infrequent, which handtype is relatively frequent?

[bluecalm]

It's more like 15.5% for just 5-3-3-2's and 19.5% if you include 3-5-(Hx-4)'s.

My view is that Gazilli does great job on most hands and it will be hard to make-up for loss of 1NT by improving on it, especially if that means you must raise to 2S with every 3-5-(2-3).

when we were comparing possible methods I also dealt a lot of hands and looked at possible auctions. We decided we didn't want to play a method where you had to raise a 4+ card 1S response to 2S on a 35(32)s, as that was often the wrong contract. Playing in 2M rather than 1NT we already knew we were comfortable with, because it's the same as playing a (semi-)forcing 1NT response.
