Let's say we're playing something similar to Precision, so we open 1M with perhaps 10-15 hcp and 5+ major, even when holding a longer minor.

Which methods do you use to show 5-5 or better, let's say after a negative NT response from partner?

To me, this seems like "standard":

1H-1NT;
2m = 4+ minor, minimum if 5.
2H = 6+ hearts. Single-suited?
2S = 6 hearts, 5 spades.
3m = At least 5-5 and extras, about 13-15. Could be 6-5 with unknown length.

Same principle after 1S-1NT, but perhaps 6 spades and 5 hearts can jump to 4H with max... Not sure.

AWM suggested using the 2NT rebid as 5M and 6m. Not sure what he uses 3m for, perhaps 5-5 and max (or perhaps 6M and 5m).

Transfer rebids are another approach that tend to work well for 5-5 hands.

Modified Gazzilli.
If 1♦/1♥/1♠ = NAT 10-15 HCP, then define

• MIN = 10-13 HCP.
• MAX = 14-15 HCP.

After 1♠ - 1N - ; ??

• Pass = NAT. BAL. MIN
• 2♣ = ART. Gazzilli. MAX or 6+ original suit.
• 2♦/♥ = NAT. MIN. 4+ Bid suit.
• 2♠ = NAT. MIN. 4+ ♣s.
• 2N = ART. MIN. 6+ ♠s 4+ other.
• 3♣/♦/♥ = NAT. MIN. 5+ bid suit..
• 3♠ = NAT. MIN. 7+ ♠s.

After 1♠ - 1N -; 2♣

• 2♦ = ART. MAX. 10+ HCP.
• 2N = ART. MIN. ms
• Other = NAT. MIN. 0-9 HCP.

After 1♠ - 1N -; 2♣ - 2♦; - ?

• 2♠ = NAT. MIN. 6+ ♠s.
• 2♥ = ART. MAX. GF.
• Other = NAT. MAX, GF.

We play Gazzilli wherever possible e.g.

1♦ (1♥) _X (_P); ??

• 2♣ = ART. 6+♦s or MAX.
• _P/1♠/1N/2♠ = NAT. MIN.
• 2♦ = NAT. MIN. ♣s and ♦s

It started out as Precision, however, not much stayed the same meaning.


1M-1N-3m is 6M and 5m. This makes it much easier for responder to bid now.

Bidding 1M-1N-3m with 5-5 gets you to the 3 level fairly often is without a fit.

Remember following the LAW is a very good idea.


Partner does not have a major fit in most bidding methods unless they have a 3 card limit raise.

You are jumping to 3m hoping that responder has a minor fit and game values.


Playing 3m or 3M in a 5-2 fit or even a 5-3 minor fit(if partner is weak) is no fun.


Good partners invite when they have invitational values after 1M-1N-2m

Trust partner to bid their own hand.


If really worried about missing game, Gazzilli provide a strong measure of safety.

It's only important to jump when we are likely to make game on hands where responder would not invite. Keep in mind that responder knows opener's point range and both the long suits (so he can upgrade with a great fit for the second suit).

You're not that likely to make 3NT on substantially less than 25 hcp just because opener is 5/5. So we're aiming for eleven tricks, and we don't think it's that likely to make on hands where responder won't find a raise (keep in mind we will raise pretty aggressively with FIVE-card support). Anyway, we prefer to reserve all jumps for 6-5 hands, and we use 2NT to distinguish which suit is longer.

[steve2005]

In standard you have the power to go to the 3-level on 5-5. Not so with Precision.
You can easily end up in a 5-2 fit at 3-level on 14 opposite 7.
I agree with spotlight you need 6-5 for the 3-level almost all the time.
This doesn't mean at your second bid you won't be bidding at 3-level on 5-5 but partner will have shown something then.

Personally I think Gazzilli is overkill with Precision. What you really need is partner to have values not distinguish between you having 11-13 and 14-15.

[Trick13]

1M - 1M+1 is an enquiry and we only go above 2M with a freak
1M - 2x is a transfer and we only break the transfer with a freak

For the freaks:

2NT is 5M-6m
3m is 6m-5M
3M is 7M
2S/3H is 6M-5OM

[Kungsgeten]

I've seen several Gazzilli/Häxan pairs who, after an "unlimited" 1M opening, jumps to 3m with 13-15 and 5-5. I think the Italians jump with a bit more, something like 15-17 and 5-5 (so 5-5 through Gazzilli is GF for them). I think this may be because several Italian pairs tend not to open 1NT with a five card major?

If playing limited 1M, I guess one of the upsides of bidding 3m with 5-5 and max is that responder might invite a bit less aggressively, as in passing the 2m rebid instead of bidding 3m or 2NT.

I'm considering something like the following, myself. Our 1M is 5+ suit with 11-16, 11-13 if balanced. Our 1NT response denies support and is non-forcing.

1M-1NT;
2C = 6+M. May have a 4+ side suit.
2D = 4+D.
2M = 4+C.
2oM = Natural (1H-1NT; 2S show 6-5).
2NT = 6m, 5M.
3CDH = 5-5, 14-16.
3M = 7+M, extras but not max.

The 2C rebid is mostly stolen from Ulf Nilsson.

1M-1NT; 2C---
2D = Positive relay, at least mild game interest. Doesn't promise a fit.
2M = To play. Can be void. Opener can bid 3m with 6-5.

1M-1NT; 2C-2D;
2M = Minimum.
2oM = 4+m, or 4oM.
...Relay = Asks
......3m = 4m.
......3H = 5C.
......3S = 5D.
......Other = 4oM.
2NT = Extras, scattered values. Non-forcing.
3new = Shortness, extras. 3M now is non-forcing.
3M = Extras, usually no shortness (can have short spades after heart opening). Non-forcing.
3NT = Too good for 2NT.
4H = 6S, 5H (after opening 1S).
4M = Too good for 3M. Probably 7222.

Maybe, with

MIN = "11-13 unBAL or 12-14 bAL"
MAX = "14-16, unBAL",

1♥-1N; ?:

P = MIN, 5H4-D4-C
2♣ = "6+ H" (=> 2♦ = INV+ relay (=> 2♥ = MIN; 2♠+ = GF))
2♦ = 5H5D OR MAX, 4+ D, not 5H6+D (=> 2♠ or 2N = relay (=> 3♦ = MIN, 5 D; other = GF))
2♥ = 5H5C OR MAX, 5H4B3-D (=> 2♠ = P/C; 2N = relay (=> 3♣ = MIN, 5 C; other = GF))
2♠ = MIN, 5S6+H
2N = MIN, 5H6+m (=> 3♣ = P/C; 3♦ = GF relay)
3♣ = MAX, 5H6+C
3♦ = MAX, 5H6+D

1♠-1N; ?:

P = MIN, 5S3-H4-D4-C
2♣ = "6+ S or 4+ H" (=> 2♦ = INV+ relay (=> 2♥ = MIN, 4+ H; 2♠ = MIN, 6+S3-H; 2N+ = MAX (GF)); 2M = WK, PREF opposite 5S4H)
2♦ = 5H5D OR MAX, 4+ D, not 5S6+D (=> 2N = relay (=> 3♦ = MIN, 5 D; other = GF))
2♥ = 5S2+H5C OR MAX, 5S2-3H4C (=> 2N = relay (=> 3♣ = MIN, 5 C; other = GF))
2♠ = 5S1-H5C OR MAX, 5S1-H3-D4C (=> 2N = relay (=> 3♣ = MIN, 5 C; other = GF))
2N = MIN, 5S6+m (=> 3♣ = P/C; 3♦ = GF relay)
3♣ = MAX, 5S6+C
3♦ = MAX, 5S6+D.

As usual, the goal has been to avoid 2N and unLawful 3-level contracts as much as possible.

After 1♠ - 1NT*

2♣ = min, not 4♥ or 6♠
2♦ = max, not 4♥ or 6♠
2♥ = 4♥
2♠ = 6♠

... freaks

After 1♥ - we use 1♠ as the enquiry so that we have enough steps. You can use the same scheme (bonus 1♥-1♠; 1NT-Pass) or something a little better (focus on majors)

1NT = 6♥ or 3♠

2♣ = further enquiry focussing on ♥
2♦ = further enquiry focussing on ♠

2♣ = not 6♥ or 3♠
2♦ = 4♠ min
2♥ = 4♠ max

... freaks

We don't do anything special with 5-5s. They generally disappoint. Maybe we could take some of the stronger 5-5s out of 1♣ to make 1M-1NT-3m more frequent?
