Since Leia's corvette was overtaken and captured by Vader's Star Destroyer, she figured out that Kenobi was "her only hope" to get Death Star plans to her father on Alderaan.
Was linking up with Kenobi part of the original plan, or did that only come out because of her ship's capture?
If it wasn't part of the plan, how did it manage to happen that her ship was captured exactly over Tatooine, which is a random hole in the underbelly of the Galaxy?
