Every year at about this time, I discover a deep love for tennis and/or James Blake. The problem is, for me, watching tennis is sort of like listening to Alizee: I love it, but I have no idea what's going on. Love, 15, 30, 40, game, right? And a match is all the games played, and a set is...somewhere in between there? Can anybody direct me to a good, simple guide to tennis for viewers? Thanks.
