The "strong" side player usually, but not always, plays the left side. This is
only because more of you are right handed and will have your right hand inside
the court on that side. You can switch roles at any time. As you play with this
partner for a while, you will fine tune this practice. Eventually, it will
happen automatically, without talking about it. You will just see in your
partners approach if he is going for the strong role or letting you take
control. It is when it gets to this level of non-spoken communication, a GREAT
TEAM is created.
