I was going to call it the cross court forehand, but an inside-out forehand is technically also a crosscourt forehand, so I will resort to using the term "outside-in" forehand, which is hitting a forehand from your forehand side of the court crosscourt. A player with an extreme forehand grip tend to have a more open stance: View from top -<> arm body To hit an outside-in forehand in the same stance, he needs to contact the ball further in front: View from top \<> arm body (this is too steep but you get the idea) However, this seems to allow the player little power as the contact point is further away from the body and his stance is even more open, allowing little "rotation into the ball". Of course, a player can always adjust by doing the split-step even more towards the location he wants to hit the ball to and execute the stroke as if he is hitting in a straightline, but that requires more time and is hard to execute when the player is moving laterally from side to side during a rally. Players with extreme grips like Nadal, Djokovic and Andreev all have spinnier outside-in forehands and more powerful inside-out forehands. I don't think it is a conincidence. I play with an extreme grip too and I feel that I hit the ball harder down the line than hitting it outside-in. Is my analysis right? Please correct me if I am wrong.
