Tolong jelaskan mengenai Hobby Bermain Catur dari Ray Charles

Charles enjoyed playing chess. A part of his therapy when he quit heroin, he met with psychiatrist Dr. Friedrich Hacker (de), who taught him how to play chess, three times a week. He used a special board with raised squares and holes for the pieces. When questioned if people try to cheat against a blind man, he joked in reply, "You can't cheat in Chess... I'm gonna see that!" In a 1991 concert, he referred to Willie Nelson as "my chess partner". In 2002, he played and lost to the American grandmaster and former U.S. champion Larry Evans.
