Flem72 Posted June 29, 2014 Report Share Posted June 29, 2014 We're thinking of using a 2D opener as a weak 2 in H or a couple of strong options. Where does this land on ACBL convention charts?

Vampyr Posted June 29, 2014 Report Share Posted June 29, 2014 I can't get the link properly on my tablet, but it is a Midchart convention.which seems an odd choice, but it is an ACBL Convention Chart, so odd is probably the default! Quote Link to comment Share on other sites More sharing options...

steve2005 Posted June 30, 2014 Report Share Posted June 30, 2014 Midchart (and there isn't an approved defense to transfer preempts with a strong option)There is an approved defense to 2♣ as weak ♦ or strong. you would have to get approved. Easier to go multi with weak ♥ or ♠. maybe make spade either good or bad pre-empt as it sounds like you still have a natural ♠ preempt Quote Link to comment Share on other sites More sharing options...

Mbodell Posted June 30, 2014 Report Share Posted June 30, 2014 How do these approved defenses work? They don't. Essentially if the defense is already approved, you can use the convention, but often need to provide the opponents 2 copies of the approved defenses. If there is no approved defense and/or if the convention is not allowed in midchart (a revision to the midchart a few years ago changed from a bunch of rules of what was fine if there was a defense to instead explicitly listing only the approved conventions) then you need to petition the C&C folks to get it approved. And they've demonstrated they rarely approve anything and they've said they are not interested in approving additional preemtive/weak/multi-way bids.

paulg Posted June 30, 2014 Report Share Posted June 30, 2014 We're thinking of using a 2D opener as a weak 2 in H or a couple of strong options. Where does this land on ACBL convention charts?We used to play this at NABCs a few years ago. Before doing so we asked both the Competition & Conventions Committee and the Chief TD whether it was permitted at Mid-Chart. Naturally we never received a reply from the C&CC but the CTD said that it could be played so long as the Multi 2♦ defense was provided. This decision was upheld the few times that our opponents asked the TD about it, including both times when Steve Robinson asked them. When we played Meckstroth, who is on the C&CC, he did not dispute its legality but thought the transfer pre-empt defence was more appropriate. We now play a full Multi so it has not been an issue for the last couple of years. I recommend that you contact the C&CC (http://www.acbl.org/about-acbl/administration/competition-and-conventions-committee/) and ask them whether this is still seen as subset of the Multi 2♦.
