Now, I'd love to spend some of the time getting up to speed the next couple months really learning 2/1. I know this question is probably oft-asked, but I couldn't find a good thread via the search (sorry in advance if I'm just screwing up)... But, I'd love to know what the forum-ites think is the best 2/1 resource (book, etc) for something approaching 'expert standard' bidding these days. I have looked at the BBO Advanced card for starters and done some googling, but I'd love some informed input before I start down the path to destruction.

Thanks. And great to be back reading y'all's posts.
(Mods: If this is in the wrong sub, I apologize and ask that you'd move it)
