Lynn Davis Deas (born June 16, 1952) is a professional American bridge player. Sometime prior to the 2014 European and World meets (summer and October), she ranked 22nd among 73 living Women World Grand Masters by world masterpoints (MP) and 3rd by placing points that do not decay over time.
Deas is a native of Newport News, Virginia, near Norfolk, where she was a student at Eastern Virginia Medical School when she suffered a bad automobile accident in 1980. Already an avid bridge player, she played "all the time" when broken bones and blurry vision forced her to take one-year leave from school, and subsequently decided to drop out in favor of the card game as a career.
At one time Deas ranked first among Women World Grand Masters. At one time she was on the road as a professional player for 30 weeks a year. She was diagnosed with muscular dystrophy in 1997 and reduced her travel. As of January 2012, she lived in Schenectady, New York. Online she advertises teaching and coaching services, as well as playing.
At the inaugural SportAccord World Mind Games in Beijing, December 2011, Deas and Beth Palmer won the "Pairs Women" gold medal. Not a world championship meet, the SportAccord WMG invited 24 women from Great Britain, France, China, and the U.S. to compete in three small tournaments as four national teams, twelve pairs, and 24 individuals. The six U.S. women also won the Teams gold medal. Beside the two gold medals Deas won $8000 in cash prizes.
