A former computer programmer and options trader, Larry Cohen was for many years a full-time bridge professional and part-time golfer. Now retired from serious competition, he travels from his home base in Boca Raton, Florida, to fulfil his numerous lecturing engagements, and he writes regularly for several magazines. He has twenty national championships to his name, as well as two world championship medals. He is perhaps best-known for his classic book, To Bid or not to Bid, which at the time was the best-selling book on the game since Charles Goren's heyday (it has since been surpassed by 25 Bridge Conventions You should Know).
