I notice that my whole life as a tennis player I have developed a habit of closing my racquet on forehands and opening it on slice backhands. It took me a long time to figure it out, but basically when I slice sometimes, right at contact I roll my wrist back and the racquet head opens up too much. On forehands this results in closing the racquet face too much and sometimes framing the shot. I have always hit with a ton of spin and I wonder if this risky habit is what gives me so much spin. The best way to describe it is that if you put your right hand in the thumbs up position, then rotated your wrist so the thumb faced horizontal towards your left. I am working on keeping my wrist bent longer and firm on contact so I do not this, and focus more on wiping the ball across. I do this motion also, so that is why the whole thing is kind of complicated. It is almost like I am playing ping pong with tennis equipment. Is there any way to really focus on your wrist on contact to fix this? I am slowly fixing it on my slice backhand by trying to push the ball back a lot more with my shoulder instead of using my wrist but this is a tough habit to break. I also am not sure if some of this motion is actually good and helped me develop such heavy spin.
