Part of working out the kinks was the MOST excellent suggestion that the problem hands be posted in individual threads so that users can discuss the hands in threads dedicated to that hand. So here goes, we shall jump the gun by posting the first problem hand today, and then subsequent problem hands later.
The discussion of this hand is now open. In a day or two, I will post what the experts thought about this hand. Did you vote for PASS, 1♦ 1♥ 2♦ 3♦ or something completely different?
