You are indeed in the wrong. I will try to explain why.

Imagine I was your partner: here is what I see – my partner plays a lovely block and moves forwards aggressively to attack the net. As my partner moves, I move as well, covering the empty space at the rear of the court, trusting my partner to cover the midcourt and front court (but maybe not a fast straight drive – tough to cover the whole midcourt by yourself!).

Then, my opponent does exactly what we wanted, he lifts it over my partner… who apparently doesn’t trust me and so is coming to barge me out of the way. We are both now at the back of the court, and my partner has left a glaring great gap at the front of the court. Cheers partner. Good game.

As your partner, the question I ask is… if you wanted to cover the back, why did you move forwards? If you were wanted to attack the net, why aren’t you letting me do something? You are not really working with me, you are not setting me up, you are playing singles.

I suggest that you need to shift your thinking into one that is more aggressive – working with your partner. I can tell you now – you do not need to defend my backhand – I can hit a backhand clear, and my round the head smash is more powerful than my regular smash. Instead, why not just be really aggressive at the net – then you turn from an annoying partner into an awesome one!

But thats just my view

No worries. I play with a guy who does exactly as you described – he goes to the front to play net, and then comes to the back and smashes. Its “annoying” when you first play with him, but then you realise he is an exceptionally fast singles player with a smash like a thunderstrike – it actually works quite well and we win a lot of points (he will come forwards after the smash to attack the net). However, it is NOT good doubles, and will confuse many players and worst of all, against an opponent who has excellent defence, we will not win points because we are not working together. So, it can “work”, but its not doubles!
