The higher ground
In Revenge of The Sith, Obi Wan takes “the higher ground”. Anakin is unable to force jump out of range and Obi Wan cuts off his legs. But....
Phantom menace has a similar situation. Obi Wan is hanging on for dear life several feet below Darth Maul with Darth Maul hovering over him. How come Obi Wan can leap over Darth Maul without Maul cutting him in two?
