Using the pause trick. Run at a 90 degrees at them (not directly at them, or they'll kill you), and if they move out of their place while you're getting away, hit space to pause. Quicksave while paused. Prepare to move just an inch and pause again. If it happens successfully, pause and quicksave again. If not, restore the old game. You have the advantage of the paused game to try the same.
This way you can kite any map guard who is not in a really tight spot. The ones in tight spots... You can't, unless you get lucky, and to get lucky it takes a ton of attempts.
Oh, and it needs a lot of practice. So practice, guys
