dont know if its just me, but the L1 & R1 buttons seem to do jack- L1 is supposed to run you to the middle, and R1 is supposed to run you to the net...
they dont...
They do it's just not that instant. Hold down L1 and he moves to the most likely position, hold R1 and as you play shots he works his way to the net. This is not instant and happens as you play shots.
To be honest I think they are pony and you may as well use the analogue stick to position yourself.
Anyone got right stick serving nailed yet?
