Have we entered Superman's Bizarro World? Is black now white?  Is up now down?  No....but Larry Cohen is now teaching Conventions!!!  In the 10th book in the popular and award winning "Larry Teaches" series Larry addresses all the conventions you should know, and those you should avoid. The book focuses on the "Big 4" Conventions (Negative Doubles, Stayman, Blackwood and Jacoby Transfers).  There are a few others that Larry explains and gives suggestions on whether or not to play them.
