A picture is worth a 1000 words. Here's the best player ever hitting a topspin forehand. Primary ingredients R:
1 - Racquet face is closed.
2 - Ball contact is on the top half of the ball.
Top = Topspin; it's a tangent line at approx 30deg above
the equator in the ball's N Hemisphere.
3 - Flight contact focus @ the Apex, i.e. at Level Flight. This becomes automatic in due course.
