Since I brought up Bergen's law of 20, I would like to add something here. First of all, Bergen's law of 20 is just a reference, I don't follow it strictly. For the hand Roland gave (SQxxxx, HKxxxx, QJ,Q), I would not bother to count the points: the quacks in the minors don't count at all. I also use Zar points as a reference for opening, but don't follow it strictly either. I wouldn't open a slightly better hand like SKxxxx, HKxxxx, DQJ, CK, which has 12 hcp, 22 of bergen's count, and 27 of Zar points.
