Like most people, my most effective shot is my forehand. I can put a lot of pace into a shot, I can put a lot of spin, or I can do a measure of both (which is my standard rally shot). It is also the only shot in my arsenal where I can hit angles consistently. The lasso-follow through also allows me to mix it up, which I can't do with my backhand.
I am an unpredictable player. Even I surprise myself with some of the shots I make.
