Includes teacher-friendly features, such as the ability to print out a complete hand diagram for each deal. Based on the popular Bridge Buff software from BridgeWare Inc. When the Practice Your Slam Bidding software appeared in 2003, the American Bridge Teachers’ Association said ‘If you liked the books, you’re going to love the CDROM.'.
