1. Get a good aim while shooting and moving with the ship while dodging your enemies bullets. 2. Then learn about controlling your energy bar on top of screen (how much energy bullets take when they hit you and how much you loose for shooting). 3. Try your best, if you really want to win the duel, then focus and keep your guard to play as long until your opponent makes a mistake (overshoots a bit or gets hurt from a stream of bullets and tries to run away to recover [this is when you should chase him to finish him, if you have the chance from a distance]. 4. Just do well timed bullet streams to your opponent from being still and shooting to different directions at him closely, so he cant escape and when you finally get a few bullets hit to him you just push forward with your aim and bullets at him. 5. Use your thruster (shift button) to escape from narrow situations from being almost killed by your enemy in a duel. 6. Dueling is all about the movement and timing, this means that the more accurate you are in flying the ship and managing your energy and the less accurate your enemy is (than you) then you have a greater chance to win a duel. 7. Believe in that you will win and that your enemy is easy to defeat and that he isn't better than you are.
