There are some of the bridge books that have been the most useful to me:
2 Over 1 Game Force by Audrey Grant and Eric Rodwell. This book explains a popular variation of Standard American bidding. Small modifications involving the use of 1 NT response as a forcing bid can make it easier for the partnership to get to the best game contract and explore the possibility of slam.
Bridge for Dummies by Eddie Kantar. I taught myself the game using this book. It covers the fundamentals of bidding and card play and provides a solid foundation on which to build.
“Contract Bridge Bidding Guide for Standard Bidding with 5-Card Majors” (Basic / Intermediate / Advanced) by Michael Furstner
“Hand and Suit Patterns” by Ken Monzingo (probabilities)
“High Card Points in a Random Bridge Hand” (probabilities)
To Bid or Not to Bid by Larry Cohen. This book teaches the correct use of the Law of Total Tricks.
