  Are you recovering from Sinq Cup withdrawal? If so, we have just the remedy. Grandmaster Pal Benko, who recently celebrated his own 87th birthday, composed a set of problems for Chess Club founder and president Rex Sinquefield’s 71st birthday on September 7, 2015. The series includes mates in three in Rex's initials, and his age. See how quickly you can solve all 8! Rex and his wife Dr. Jeanne Sinquefield were recognized by 2015 Sinquefield Cup Champion Levon Aronian in a heartwarming speech, who said: "In (the) history of chess, I don't know anyone that has had so much love for chess."
