Scenario: You're sitting at a NLHE table, you've been playing for a bit and you find you are involved in a hand against a villain who is playing 13/9 pre-flop.
Challenge: What does their pre-flop play tell you about their big-picture strategy? What are their motivating goals and fears? What is a good range to put this opponent on? How would you adjust your play to deal with this villain?

Objective: How much information do you glean from those 2 numbers when they're not your own?
