Am a serious beginner using SAYC as system. I'm reading many books based on 5 card majors and SAYC. Each mentions calculating "quick tricks" (also called "defensive tricks") such as AK = 2 quick tricks, AQ = 1 1/2 quick tricks, etc. during bidding. This is not the same as counting "sure tricks" for play of hand planning. Besides using quick tricks to evaluate a preempt response these books also mention using this calculation when thinking of opening with a questionable hand and when thinking of doubling opponent. My questions are: 1. What is an minimum, average, and good number of quick tricks? 2? 2 1/2? How do I know a good number of quick tricks for a minimum opening hand? 2. What is a good number of quick tricks for doubling a contract? How do I incorporate this information with other facts such as singletons, or strength in opponent suit. Do I count on a minimum number of quick tricks from partner when making decisions? If so, how many? I guess, basically, I don't understand the concept of "quick tricks" and how to benefit from their use. Sue in Virginia
