For those who play sound reverses

[nullve]

@DavidKok (minor thread hijack):

 

 

 

Compared to T-Walsh where 1NT always shows 17-19 BAL you get more definition in your strong versus weak long club hands, but you might end in a suboptimal spot if opener is weak and unbalanced (for example hand type b might present issues, responder has no way to give preference to diamonds on the 2-level).

I used to open 1N ("14-16 BAL") with hand type b), but that leads to insolvable problems after Crawling Stayman. Now I play

 

1♣-1R; 1N-2♣; 2♦ = 13-15, 22(54)

 

after which Responder can usually place the contract. (Worst case scenario is when Responder has 4423 opposite 2254.)

 

With hand type c and no second suit (so let's say 6 clubs) do you raise 2♣ to 3♣?

Over 1♣-1♥; 1N-2♣ I do.

 

Over 1♣-1♦; 1N-2♣ I can choose between

 

2♠ = "16-18", 3S1-H4-D5+C

2N = "15-17", 2-S2-H4+D6+C

3♣ = "16-18", 2-S2-H3-D7+C.

 

 

Do you run into any issues with responder having both majors on this sequence in your system, or a weak hand with a single major? When, if ever, does responder break the Gazzilli bid with 2♦ and up?

Responding 1♦ even with longer S (unless GF values) seems to work well enough constructively.

 

A few illustrative sequences:

 

1♣(1)-1♦(2)

1N(3)-2♣(4)

2♦(5)-2♠(6)

P

 

1♣(1)-1♦(2)

1N(3)-2♣(4)

2♥(7)-2♠(8)

P

 

1♣(1)-1♦(2)

1N(3)-2♣(4)

2♠(9)-P(10)

 

1♣(1)-1♦(2)

1N(3)-2♠(11)

P(12)

 

(1) as above

(2) "0+, 4+ H, may have longer S unless GF values"

(3) a) "10-12", 3-S2-H6+C b) 13-15, 22(54) c) "16-18, 3-S2-H5+C, unBAL" d) "17-19 BAL, 2-3 H"

(4) to play opposite a)

(5) 13-15, 22(54)

(6) 5+ S, to play

(7) "17-19 BAL"

(8) 5+ S, to play

(9) "16-18", 3S1-H4-D5+C

(10) 4+ S, weak

(11) (delayed) INV Reverse Flannery

(12) "10-12", S tolerance (as expected)

 

Do you run into any issues with responder having both majors on this sequence in your system, or a weak hand with a single major? When, if ever, does responder break the Gazzilli bid with 2♦ and up?

1♣-1♦; 1N-2♥ = "7-12, 6(+) H" ["8-12" might be a better range]

1♣-1♥; 1N-2♥ = "7-9, 6(+) S" ["8-10" might be a better range]

1♣-1♥; 1N-2♠ = "10-12, 6(+) S" ["11-12" might be a better range]

1♣-2♦ = Multi: "4-6", 6(+)M3-OM ["5-7" might be a better range]

1♣-2♥ = Major Flash: "0-3", 6(+)M3-OM ["0-4" might be a better range].

 

When, if ever, does responder break the Gazzilli bid with 2♦ and up?

1♣-[1M-1]; 1N-?:

 

(...)

2♦ = ART GF (and the "positive relay" in Gazzilli jargon)

2M/OM: as above

2N = "10-12", 4-5M1-OM

3♣ = "7-9", 4-5M1-OM

 

(The 2N and 3♣ responses are there just to complete the particular "NT system" I currently use after

 

1♣-[1M-1]

1N-2♣

2M.)
