That sliced forehand can be a formidable weapon, and at pretty high levels, including 5.0.
I used to practice occasionally with an old feller by the name of TomBrown. He was so wrinkled and decrepit I was sure I could snuff him off the court. Guess what? Even winning 3 rounds in A/Open, I couldn't. His slices, angles, dink teasers and low level sliced lobs were confounding me, and most of the other A/Open players of the mid '70's. Not all, of course. The top 20 in NorCal would just hit winners against him. I was closer to bottom 200.
