Simple Gazzilli

Sure, now-a-days you can see version of Gazzilli on every site and about every expert's convention card. And there's a reason for it. It's made to handle some of the most awkward hands for the natural system. The focus is in getting to possibly worse partscores but never missing good games and having very accurate and good auctions on slam hands. This is partly my own, partly something I've read somewhere and in no way special version, but as I had to write it for system notes anyways, could as well write it here.

Three different sequences: 1H - 1S - 2C, 1H - 1NT - 2C and 1S - 1NT - 2C, last is similar to second so I'm not writing it out. 1S - 1NT - 2C - 2H = natural, weak.

1H - 1NT (SF)
->
2C = Gazzilli, 6+H, 10-14(15) or 14-16 balanced or various 17+ hands
2D = Nat, 10-16
2H = 5H, 4+C, 10-16
2S = 10-15, 5S6+H
2NT = 17-19 Bal
3C/D = 15-17, 55+
3H = 15-17, good suit
3S = Autosplinter
3NT = Solid suit, mildly slammish
4C/D = Autosplinter

1H - 1NT - 2C
->
2D = 8+, GF opposite any strong hand
2H = Weak preference, <8HCP, 1-3Hs
2S = <8HCP, 0-1H, long D
2NT = <8HCP, 0-1H, both minors
3C = <8HCP, 0-1H, long C

1H - 1NT - 2C - 2D
->
2H = 10-14, 6+H, NF
2S = Natural, GF
2NT = Natural, 14-16
3C/D = Natural, GF
3H = Natural, GF
3S = 56, GF
3NT = Solid hearts, strong slam interest
4C/D = Natural, at least 55, 3-4 losers

1H - 1NT - 2C - 2H
->
Note! With 14-16bal you are supposed to pass and hope for the best.
2S = Natural reverse, one round force with natural continuations (No leb applies)
2NT = Naturalish invite, typically some 5422 shape or 5431 with singleton honor.
3C/D = Natural invite, usually just 4 cards and hole in suit so no 2NT. Could be 64
3H = Natural invite
3S = Slammish Hs
3NT = To play, usually based on solid hearts
4C/D = 55+ GF

1H - 1S - 2C
->
 2D = 8+
2H = <8, pref 1-2H
2S = <8, 5044 or similar (We have 1H - 2S as weak, so can't be weak 6+)
2NT = <8, 6+D
3C = <8, 6+C

1H - 1S - 2C - 2D
->
2H = 10-14, 6+H
2S = GF with 3+S
2NT = 14-16 bal
3C/D = Nat, GF

3H = Natural, GF
3S = 3S, 6+H GF
3NT = Solid hearts, strong slam interest
4C/D = Natural, at least 55, 3-4 losers

1H - 1S - 2C - 2H
->
2S = Contract improvement, 3S
2NT = Naturalish inv
3C/D = Natural inv
3H = Natural inv
3S = Natural inv
3NT = To play
4C/D = 55+ GF

Easy, simple, effective. I think the gains easily cover the losses. I might later add here some continuations for 1H - 1S - 2C - 2D - 2H, as responder is unlimited and there might be reason to add some artificiality.
