I partnered with someone yesterday, and we had the following case. Opponent lifted to my right corner. I smashed (straight) along the tramlines, and my partner was dutifully in the front. The right opponent blocked (dropped) straight on the tramlines, and the partner couldn't make it. He told me that I wasn't doing him any favors with such a shot, and unless I can cover the tramlines (I couldn't, I was too far back), I should hit more to the left (instead of a "key" shot?). I told him that I'm always smashing straight so he can bias and stand a bit more to my side. He told me that still it's better to go for the 1/5-1/4 of the court (horizontally). What do you think? Whether the partner should have made it to the shot or not, in terms of optional angles for the opponent, is it good to push him to his backhand corner, or should I go for about the middle (horizontally) of the right opponent's half? What's better for my partner?
