About the Players

Lynn Baker
{mosimage} Lynn is a law professor at the University of Texas, and frequently serves as a consultant to other attorneys on issues of legal ethics in mass tort settlements.  A graduate of Yale Law School and Yale College, she also holds a degree from Oxford University, which she attended as a Marshall Scholar.
A 14-time National Champion, Lynn’s work commitments largely limit her tournament play to National women’s team and pair events.  In 2009, Lynn was on the USA I team that won the silver medal in the World Championships (Venice Cup) in Sao Paulo, Brazil.  In 2001, Lynn was on the USA I team that finished 5th in the World Championships (Venice Cup) in Paris, France.
A lifelong athlete, Lynn rowed for the Yale Varsity Women’s Crew and was selected to one U.S. Olympic and three National Women’s Rowing Team training camps during college.  An avid downhill skier and runner in recent years, she has completed four marathons.  She lives in Austin, Texas with her husband, Sam Dinkin, their 14-year-old daughter, and a kitten, Reginald.
Karen McCallum
 {mosimage}A five-time world champion, Karen is perhaps best known for her aggressive and complex "light initial action" bidding system.  Although the five-card (non-vul) "McCallum weak 2-bids" (with no restrictions on suit quality or side holdings) are no longer an oddity among experts, Karen saw their promise in the 1970s.
Respected around the world as a bidding theorist as well as a player, Karen has served as a coach of several Turkish national bridge teams (open, women, and junior), and of the Australian open national bridge team.  She was the NPC for the Turkish juniors in the 2000 Junior World Championships in Antalya.  Karen has been an invited participant in bidding panels in numerous bridge publications in England, Australia, Turkey, New Zealand, France and the US.  She has also edited several bridge books, including the best-selling bridge book of all time, Larry Cohen's "To Bid or Not to Bid."
In addition to her great success in women's bridge, Karen has had some memorable experiences in open bridge.  She was invited (with her partner, Kerri Sanborn) to play in the 1990 Rosenblum Teams with Peter Pender, Ralph Cohen, Bob Jones, and Mike Smolen, and the team faced a formidable opponent in the round of 16: Bob Hamman, Bobby Wolff, Chip Martel, Lew Stansby, Jimmy Cayne, and Chuck Burger.  At the half, Pender's team was down 15 IMPs, and one team member suggested that perhaps "the four guys" should play the rest of the way.  But Pender sent in McCallum and Sanborn for the second half and won the match.  Pender's team eventually lost in the round of 8 to the German open team that won the event.

A woman of many talents and interests, Karen's primary work outside bridge is creating hand-crafted glass and beaded jewelry.  You can see examples of Karen's stunning work at  She is an insatiable reader of all genres, with a home library of more than 50,000 volumes.  She also enjoys gourmet cooking and playing the piano.  She lives in a 215-year-old farmhouse in Exeter, New Hampshire with her husband of 32 years, Alex.

Pamela Granovetter

Pamela Granovetter is best known for the partnership-bridge column she co-wrote with husband Matthew Granovetter, which was published in the ACBL Bulletin for 25 years. They also co-published Bridge Today Magazine for 20 years.

The Granovetters have also created a strong club system called "GUS" which they play with each other, Ron Rubin, Kevin Dwyer, and JoAnna Stansby.

The Granovetters have three sons, ages 28, 26, and almost-19. Pamela did not play bridge actively for 20 years, devoting herself to raising her sons -- and she loved every minute of it!

Since her re-entrance into serious bridge a few years ago, Pamela has had a great
deal of gratification playing in regionals, where she regularly competes against great players from North America, Poland, Australia, Britain, Holland, etc.

JoAnna Stansby


Bridge is by far my favorite endeavor.   Away from the table, I enjoy reading, hiking,  Wikipedia, puzzles, board games, and practice public speaking at my local Toastmasters club.   I don't read the newspaper or watch television - this occasionally puts me in some rather curious situations!   For my "day job" I work part-time as a pharmacist.  I live in Dublin, California with my husband Lew who is also my best friend and has been a great bridge coach for me. We have no pets except for Schroedinger's cat.
