Book excerpt: This book covers basic and advanced features of the Two-Over-One (2/1) Game Force bidding system which include Bergen and Combined Bergen Raises, inverted minor suit raises with criss-cross and flip-flop, cue bidding, modified scroll bids, and many more methods not used in Standard American or Precision. This is not a book on conventions, it is a book about bridge which incorporates conventions which allow the partnership to reach game or slam. In this regard, I have incorporated modern methods for hand evaluation developed by Marty Bergen. New bidding conventions like SARS (Shape Asking Relays after Stayman), Quest transfers and an overview of "Bridge Rules and Laws" which will improve your approach to the bidding structure you may use today.
