Hi, I have both the NBJ and WCB manuals. I have noted the WCB tripoint strategy which is based on the last 5 cards seen. I do not recall a tripoint strategy previous to WCB based on the last 3 cards. Could anyone give me an idea what part of the NBJ manual I should find a reference or is this a post WCB strategy ? Thanks in advance. Is my memory failing me ? Thanks in advance

I have the 1991 version of the NBJ manual and I am wondering if there is enough new/different information in the current NBJ manual to warrant buying the new NBJ manual if I am buying WCB ? or if I am planning to stay with NBJ ? for the time being . Thanks in Advance
