The serve return in doubles has been and continues to be the most worrisome part of my game. However, due to a committment over the last 6 months to lessons and practice, I have had flashes recently of what could be considered a respectable return of serve. I am a 4.0 mens adult player. Over the last 4 weeks I have been returning well (for me at least). I return almost always from the AD court. During this time, my opponents, which have been varied, frequently have gone to alternative formations such as the "I" and an Australian formation. This has happened so often I am wondering what is it about my return that make my opponents think this is a better option. So these are the questions ... 1) Can I take this as a sign of an effective return, or is this something that you do just to show different looks to an opponent? 2) Is it more common to line up in an Australian formation when serving from the AD side? I rarely find my opponents doing this on the Duece side. 3) Finally, aside from the obvious answer of "hit it down the line", is there other strategies I should employ to combat this look as a returner.
