In The Phantom Menace, Qui-Gon senses a strong Force presence in Anakin Skywalker. He then arranges a deal with Watto whereby if Anakin wins the Boonta Classic pod race, Watto will grant Anakin his freedom.
It is well established that both Anakin Skywalker and Luke Skywalker both have a natural gift for flying, making them some of the best pilots in the Galaxy.
However, Qui-Gon has no way of knowing this, and seems to be operating under the assumption that Anakin's innate Force will assist him in winning, rather than any "natural" talent.
Yet in the original trilogy, it isn't until Luke consciously "lets go" that he can allow the Force to guide his shot to the ventilation shaft on the Death Star, implying that actually using the Force to assist in piloting requires some level of Force training.
Did Anakin actually use the Force in the Boonta Classic, or was it merely his natural piloting talent? If Anakin did win through his talent alone, why did Qui-Gon feel this would be a valid test to see if Anakin might be the Chosen One?
