Attack with long pimples

How can I improve the attack with long pimples? (Because, when I attack with long pimples, the ball fall)

Hi Juan,

Take a look at the tutorial on Long Pimple Attack Against Backspin.  If you are trying to attacking against a topspin ball you really have to open the angle of your racket.  This is a difficult shot because it comes off your bat with backspin so you have to get the stroke perfect to get the ball on the table.
