My doubles partner and I were having a misunderstanding in the following situation: We were in attack formation. I was the back player at our back hand corner, and he was the front player biased toward the left side. Both of us are right handed. So I hit a clear from our back hand corner to the opponents' back hand corner, and I moved forward, expecting my partner to retreat and defend the right side. But both times (yes, it happened twice) he retreated and collided with me on the left, expecting me to move across the court from left to right. Does it make sense? No, I don't think it makes any sense. Before I hit a clear, he should have known the birdie was on our left side, and I had to be on the left to reply. So when we switched from attack to defense, it's most efficient for him to cover the right. I've learned somewhere that the back player is supposed to read the front player's retreating direction, and move to cover the other side, because the front player can't see the back player, and therefore the front player gets to choose which side to cover. But I don't think it applies to our situation. What do you guys think?
