I have a fairly decent forehand, which gives me a bunch of weak replies in matches. But I am not able to take much advantage of them and the rally becomes neutral after that. I need advice on hitting aggressive forehand under the following two scenarios: 1. A mid-court or deep ball which is loopy and not much pace and coming straight (meaning no inward or outward angle). I make contact near shoulder height, say in the range of 4 inches below shoulder to below head. Very rarely does it rise over the head. How to hit aggresive returns for these balls? Because I am not able to hit aggressively, I simply return them deep. But I would like to add aggression to my arsenal. I really admire how Djokovic can hit winners of these balls, esp against Nadal. 2. Similar situation as above but in this case, the ball has angle. It is going outside the court and pulling me wide. Normally, I loop them back cross court but would love to have an aggressive shot in my arsernal. For background, for both (1) and (2), if they are between knee to waist (+6 inches) high, I can hit them aggressively since I am able to use deep knee bend and core rotation much more effectively. But for high balls, knee bend does not seem natural and effective. Perhaps, my technique needs work. Thanks in advance!
