How to beat a black person in basketball?

Whenever I play pickup games with black people they always dominate me on the court. They break my ankles, shoot jump shots in my face. If i try playing tight defense they will do a crossover dribble, drive to the rim and dunk on me. If I give them space they will take a jump shot and drain it.They are also quick as a hiccup. Strong as f u c k ! What can I do?
