So Carly Rae Jepsen is around musicians all day long and can't find chess competition? She needs to hang out with better musicians: Philidor and Ray Charles are dead, but Flea, Sting, Bono, and RZA come to mind. As the previous examples suggest, having a talent and an ego big enough to assume one's name seems to help: Madonna has been known to push wood.
Both music and chess produce prodigies. Hmm.
