发明名称 Bridge bidding aid
摘要 A bridge bidding aid is designed in the form of a booklet having an oversized cover and a plurality of instruction pages that correspond to various opening bids. The booklet is devised such that, when unfolded at the center of a bridge table, the four players can simultaneously and independently consult the notes to decide on their bids. Also, the information is programmed such that when the opening bidder's notes face the opening bidder, the notes pertaining only to responding bids will face the responder and, similarly, the notes for opponent overcalls and responses will be appropriately positioned in front of the opponents.
