Natural or artificial

[mgoetze]

You know mycroft, maybe you do know a bunch of people who hold simultaneously all the beliefs you describe, but your posts have all the makings of a good strawman argument. ;)

 

I don't really care what's allowed in the ACBL but I certainly think transfers over 1♣ should be allowed everywhere. I don't mind opps playing whatever defense they like. For instance there is this pair that we play once a year that likes to play a defense including (1♣)-1♠ = 0-11 points, 2-4 spades, usually balanced, whenever they are allowed to play brown sticker defenses because the opening is considered artificial. Now the last time they did this against us I was a bit disappointed that we defended poorly and only got 1400 rather than 1700, but it still scored better than the nonvulnerable slam our way.

But my issue with this stupid new law is that while it is clear that 1♣=3+ is natural (old law), it is not at all clear what additional criteria a 1♣=1+ opening has to satisfy to be natural, since I don't believe that the intention is that a 1♣ opening on

is natural.

In the ACBL, opening 1♣ on 10=0=0=3 shape would be considered natural. But it would require a pre-alert because it's a canapé system.

Oh absolutely it's a strawman. But if you look at the 2007 thread that was quoted here, and the 'I'd like an aggressive defence to a "clubs or balanced" 2+ 1♣" [edit: post I started a while ago] or the suggested defence in Senior's booklet on transfer responses, or anywhere else for that matter, you'll see how the strawman is clothed. And if you look at some of those people, and the righteous indignity they show because they have to spend all this time and memory creating a perfect defence to <convention they don't play>, you'll see why I have my suspicions.

I don't understand the problem. Why does it matter if we call it "natural" or not, as long as it is disclosed accurately? Couldn't we call it a macguffin or anything else we want?

If it is a "strong artificial" opening, you can play anything against it. If it is "natural", you may run into brown sticker regulations...

In some jurisdictions, the system and disclosure regulations have dependencies on whether a call is natural or not.

And then, hopefully, the regulations include precise definitions on which calls are natural and which are not.

[billw55]

Ah, system regulations. No wonder it is incomprehensible.

Yep. This was the main result of the change.

 

You used to be able to play any defence to a short club. It was pretty common to play Multi Landy pre Bali, but now that is not allowed. I also used to play a 1♦ overcall as an overcall in either major and 1M as 3 or 4 cards with a longer minor. This used to wreak havoc against the overloaded club, but sadly it is no longer allowed.

Perhaps Vampyr is right that the ACBL tail is wagging the WBF dog, again. It seems wrong to ban previously legal counter-measures to conventions newly popular in America, while continuing to make it difficult or impossible to use conventions, long played in other countries (e.g. multi, strong pass)
