while watching videos on youtube I see loads where in doubles the player in the front covers his whole territory quite often by jumping. I mean, when the birdie comes high over the net I tend to leave it for the player behind me, but in these videos the front player jumps either upwards or backwards or sideways and smashes a return. Is there any special technique for doing so? When i'm standing and half crouching, i find it hard to take off, maybe my stance is wrong????? Am i making any sense??
