GCC compliant Suction

[biggerclub]

For a discussion on whether Suction is GCC compliant or not see here.

 

GCC states:

. . .

 

b) natural no trump opening bids and overcalls, except that direct calls,

other than the following, must have at least one known suit.

- Double

- Two Clubs

- Two Diamonds showing a one suited hand in hearts or spades

 

So (1NT) and then:

 

x = transfer to ♣ but if then ♦ = red suits, or ♥ = ♥ + ♣ or ♠ = ♠ + ♣ (weakish)

2♣ = transfer to ♦ but if then ♥ = MAJs or ♠ = ♠ + ♦ (weakish)

2♦ = one suited ♥s or ♠s

2♥ = ♥ + minor (INV)

2♠ = ♠ + minor (INV)

2NT = minors

 

Over strong ♣ bids (1 or 2):

 

x = transfer to ♦ but if then ♥ = MAJs or ♠ = ♠ + minor (weakish)

♦ = transfer to ♥ but if then ♠ = ♠ + minor (stronger)

♥ = transfer to ♠ but if then NT or ♣ = minors (strong/weak)

♠ = transfer to ♣ but if then ♦ = red suits

NT = relay to better minor with 6-5 or better distribution in any two suits

I don't think you have interpreted the regulatory guidelines of the GCC properly. As I read it, any conventional defensive bid after a strong (15+ HCP), artificial, and forcing opening bid (e.g., Precision 1C) is allowed.

 

Numbered paragraphs 7 and 8 under the COMPETITIVE section say this is so.

 

Number 7 says that (all) defenses to conventional calls (with some exceptions) are allowed. A strong, artificial, and forcing 1C opening is a conventional call and it is not an exception specified by the referenced other regulations.

 

Furthermore, Number 8 says that numbered paragraphs 4 through 10 under RESPONSES AND REBIDS apply to both pairs. You will note that numbered paragraph 7 under RESPONSES AND REBIDS specifically allows all artificial and conventional calls after a Precision-like 1C opening.

 

Under the GCC, you can play ANYTHING you want after a strong, artificial, and forcing 1C opening.

The OP was asking about bidding over a 1NT opening as well. I assume that the regulation you quoted does not apply there.

 

Is it possible to avoid the problem by not playing in GCC games?

Probably, but 99% (at least) of duplicate games in North America are GCC.

If it's a club game, you could apply to the management to allow a method. I think that most clubs would be amenable; they may require a write-up posted in advance. This is how eg forcing pass is played in clubs around here.

 

At tournaments I think that there are always non-GCC events available?

Good that such little things amuse Hrothgar :)

At Nationals, yes. At lower levels, depends on the District. In District 4 (Central NY, Eastern PA, MD, DE), no. at least not in my part of it.

You could probably improve this by having X->2♠ show 4♠,5+♣ and 2♣->2♠ show 4♠,5+♦. This allows the 2♠ overcall to promise a 5 card spade suit. You could of course do the same with X->2♥, making it 4♥,5+m (and the 2♥ overcall in turn promise 5 hearts) with another possibility having both X->2♥ and 2♣->2♥ show the majors with one showing better hearts and the other showing better spades.
