I know that there has to be some critical trick to hitting the "tweener shot" (a.k.a., the "Sabatweenie") (between the legs with back facing the net). Please don't direct me to that British tennis website which I've already seen from other posters. I already know that you should hit the ball when it is very close to the ground and that you should start the swing with the racket face up high. I also know that you should use a backhand grip and flick it up with the edge of the racket below the ball. These tips don't do it for me. Not even close. There has to be something else to it. Who can tell me?
