Points to look for:
- The player has started to snap his wrist and forearm both forward and sideways, rotating around the elbow and snapping the wrist in the same direction to increase the speed of the bat even further. The heavy blurring of the bat and lesser blurring of the elbow and forearm are evidence of this fast motion.
- In comparison, the upper arm and shoulder have moved comparatively little, indicating that the stroke is mainly generating its effect from the forearm and wrist snap.
- The player is attempting to contact the ball near to the top of its bounce. Contacting the ball at this point reduces the amount of lift required to get the ball over the net, which allows the player to put more speed on the ball, and also increases the amount of angles that the player can achieve. It also gives the player a few more inches of backswing to get the bat moving fast before contact is made with the ball.
- Contact with the ball is made much more on the side of the ball than in the ordinary flick - as you can see from the comparative photo. This gives the return a curved flight path.
- Although not all of the racket speed is converted into topspin (there is a significant amount of sidespin put on the ball), the ball still retains a heavy amount of topspin due to the fact that the extra torquing of the wrist and forearm have increased the overall amount of spin that can be produced.
