As a club player, I do not have a permanent doubles partner. I found about 40% percent of my random partners (mostly seniors like me-) do not move forward as you move back or vice a versa. Some of them waits until the opponent hits and then run forward if the opponent returns your smash with a stright block, but this leaves their side of the court vacant as I may also be trying to return the straight block. If this (your partner refuse to rotate) happens I will just play on my half of the court. Basically I will smash/ punch clear and move froward to defend any blocks/ drops. Please share if there is a better strategy other than the difficult task of teaching your unwilling partner the importance of TIMELY rotation.
