Designed to supplement the Laws of Duplicate Bridge and Groner's Duplicate Bridge Direction, this book combines laws and movements in a handy reference guide for directors. The Laws, Tech Files, Ruling the Game, Duplicate Decisions, Duplicate Bridge Direction and ACBLscore (windows) are compiled in one streamlined book. Club directors rely on it to help them handle on-the-spot rulings and movement decisions during duplicate games. If you run social games, you'll find it useful there as well. Restructured to be "just the facts, ma'am," this updated and condensed edition phases out the DQRC. The format and 5.5" x 8.5" size make it easy to "take it to the table" and quickly find answers. Changes to the 6th edition: Smaller & spiral bound - easier to "take to the table." ACBLscore section updated to Windows/ Updated Alert Matrix/ Incorporation of Tech Files data/
