Attacking through the middle
Hitting down the middle of the other pair is a common, low-risk attacking pattern. It crosses the lowest part of the net and can leave both players unsure who should take it.
Étape 1
You are at the net and they are at the back.
Étape 2
You volley down the middle, between the two of them.
Étape 3
Both hesitate, and the reply comes back weak or not at all.
