Rules 3 and 4 

Rule 3: Establish board control at the start of each game-even if you have to clobber some guy to do so-the first six minutes of each game is the time we establish ownership of the boards at each end of the courts. 
Rule 4: The first six minutes of the second half are equally important for 2 reasons.  That’s when you go back on the court and do your thing. That is when you go back on the court and take away the other guy’s thing.
