Shot A. If you close your racket face, and swing violently upwards at the ball, you will hit a shot with high pace and heavy topspin that also flies very low over the net. It may bounce shorter due to the spin. Shot B. If you open the racket face and swing violently through the ball, you will hit a shot with lots of pace but little topspin. It will also fly low over the net. It may bounce deeper due to the lack of spin. Both of these shots are low trajectory shots that have lots of pace (i.e. they are not loopy). But what are the pros and cons of each? Would it be better to hit shot A or shot B in most situations?
