What's the Qualify parameter , and how to set it ? A string such as "strong" or "natural" , or a HCP numeral such as "16+" or "15-17", even the length of openning suit as "2+","5+" ? Everyone knows that it's not same for the defensive bidding to nat 1c openning and strong club 1C openning, then how should we do that the system can distinguish the different ways according to opps openning ? Thanks a lots.
