By the way, I think Kevin is referring to 1X - 2♣ being GF, not to 2♣ openers.
With respect to 2♣ openers, common N. America style is 2♦ waiting, then 2NT = NF, 2M/3m being natural F1. After 2♣-2♦-2M/3♣, often the cheaper ...
Yes, I was saying:
1) 2♣ opener is not 100% GF in American 2/1 (typically), but Argine follow-ups do not appear to allow a GF continuation (e.g., 2♣ - 2♦ - 2♠ - P is a possible Argine auction)

@Max, I think proper scouting is important. Usually the #1 seed in the GNT out of the Swiss just picks whoever did worst in the Swiss (and still qualified), even though it might have been a relatively good team that had a poor day. In 2016, a strong D21 team ...
That is strange -- I can't revert my system back to that stage, so I don't know. According to their FAQs, there is supposed to be a "Create an Account" button that you use, enter your name and email for verification, and that's it, but it seems like ...
