Law knows he's just a rookie, in the big scheme of things. Strength alone won't bring him far so instead he's become a manipulative master tactician, Machiavelli model or not.

Of course it's risky. Going to save Luffy in Marineford was risky. Notice how Law doesn't intend on getting rid of Dofla yet, but what happens if Dofla hunts him down? Chess game.
