The only explanation I've ever received about this convention is 2C relays to 2D, and 2D is a GF. So I guess the question is, how is this played? What is 1m - 1M 1N - 3M 1m - 1M 1N - 2C 2D - 3M 1m - 1S 1N - 2D 2H - 3S 1m - 1M 1N - 3m I assume 1m - 1M 1N - 3(om/oM) is 55 GF. Also, with 2C -> 2D, then 2N showing a balanced invite, a direct 2N relays to clubs, which allows us to get out in clubs, but otherwise is this relay used in some way? I'm sure there are dozens of sequences I'm still missing. If anyone could shed some light on this, I would be very appreciative.
