Q

How do you count Playing Trick Points?

A

playing tricks are defined as the number of tricks expected, with no help from partner, given that the longest suit is trumps. Thus for long suits the ace, king and queen are counted together with all cards in excess of 3 in the suit; for short suits only clear winner combinations are counted: A = 1, AK = 2, AKQ = 3 KQ = 1, KQJ = 2
