The backhand punch in simple terms is an extended and more aggressive version of the backhand block, it is used when the ball is slightly higher over the net or the shot from your opponent is weaker with more topspin on it. This shot enables you to hit a stronger return instead of blocking the ball back and put your opponent under more pressure.
