The Bicolors of the opener
Jean-Pierre Desmoulins
Are you sure you have mastered the use of economical, expensive or jump two-tone? This 8-page brochure takes stock of the two-color opener.
For each of the three bi-colors (economic, expensive and jump), this brochure teaches you how to recognize them and identify their characteristics (distribution, forcing or non-forcing, point area). In addition, it details the respondent's forcing auctions against these two-colors.
