I play a two handed forehand and a two handed backhand, but my backhand slice is one handed. Last Sunday I was watching the ladies finals in Indian Wells (Bartoli/Wozniacki) on tv, and I realized that Marion Bartoli (also two hands on both sides) was playing drop shots and backhand slices with two hands. I just wonder what are the advantages of a two handed backhand slice, and if it's worth learning it as an additional stroke. Or is it a stroke one should better not play? What do you think?
