Kaplan Inversion + Gazzilli and relays

[Kungsgeten]

I've previously posted a topic on using relays after Kaplan Inversion, when also playing Flannery: http://bridgebase.com/forums/topic/64680-flannery-kaplan-inversion-combined-with-relay/

 

Now partner and I are thinking of dropping Flannery, so here's a structure I've come up with. We play limited openings (11-16) where 1H is 5+ hearts and 11-13 if balanced. The relays could probably be more effective, but I think they're pretty "natural" in terms of relays. You can not always relay the exact shape in this version. I'm including all of responder's initial options after the 1H opening.

 

1H--

1S = "Forcing NT". May be limit raise with 3 hearts, a weak heart raise, negative with 0-4 spades or (semi)balanced INV+ (or just a GF hand wishing to use relays)

1N = 5+ spades, F1. If 3+ hearts then GF.

2CD = GF, may have 3+ hearts.

2H = Constructive 3 card raise, 8-10

2S = Splinter in any suit, 4+ support, about 8-16 hcp

2N = GF, 4+ support. Usually balanced.

3C = 4 card limit raise or a minimum GF hand (may have 3 hearts)

3D = Mixed raise

3H = Preemptive

3S = Void

3N = "Pudding raise", 3 hearts and 4333 minimum GF

4CD = Void

4H = Preemptive

 

Now for the interesting part, 1H--1S:

 

1H--1S;

1N = 4 spades or any max (Gazzilli-like)

2CD = 3+ suit, minimum

2H = 6+ suit, minimum

2S = 6-5, some extras

2N = We play this as solid heart suit, if playing natural then this should probably be 18-19

3CD = At least 5-5, medium strength

3H = 7 card suit, medium strength

 

1H--1S; 1N---

2C = ART. GF vs strong hand

...2D = Strong with a 4+ minor

......2H = R.

.........2S = 4+ clubs + shortness

.........2N = No shortness, so 2-5-(42), relay to find out

.........3C = 4 diamonds + shortness

.........3D = 5+ diamonds

.........3H = 6 hearts, 4 diamonds

.........3S = 0-5-4-4, better diamonds

...2H = 4 spades, minimum

......2S = To play

......2N = R. (see below)

......3CD = INV

......3M = INV

...2S = 4 spades, strong

......2N = R.

.........3CD = Singleton

.........3H = 4-5-2-2

.........3S = 4-5-0-4

.........3N = 4-5-4-0

.........4CD = Void, 4-6-(30) or 4-7-(20)

...2N = 6+ hearts, no shortness, strong

...3CD = 6+ hearts, shortness, strong

...3H = 6+ hearts, spade shortness, strong

...3S = 1-7-1-4, strong

...3N = 1-7-4-1. strong

...4CD = 7+ hearts strong, void

...4H = 7+ hearts strong, void spades

2D = Weak, 4 spades (could perhaps also be used with invitational hands with 4 spades)

2H = Weak, 2+ hearts

2S = Weak, 3 spades, 0-1 hearts

2N = Weak, 5-5 minors, 0-1 hearts

3CD = Weak, 6+ minor, 0-1 hearts

3H = Limit raise

 

When opener doesn't rebid 1NT, 2S (or 3S if rebid at 3-level, or 2NT if opener rebids 2S) is used as the relay:

 

1H--1S; 2m--2S;

2N = No shortness, so 5422 or 5332. Relay to clarify.

3C = 4-c minor + shortness

3D = 5+ minor

3H = 6-4

3S = 5440

 

1H--1S; 2H--2S;

2N = No shortness

3CD = Shortness

3H = Short spades

3S = 1-7-1-4

3N = 1-7-4-1

4CD = 7+ hearts, void

4H = 7+ hearts, spade void
