That turn around and head on works great in ALL racing games. I remember when I used to play virtua racer on my 32X (sigh), and because there are computers, and they tend to never fall more than a few seconds behind, if you can head-on the other human player, you won\'t win, but he\'ll lose.
In fighting games, for instance MK2, you can learn to master a set of cheaps. So if I was playing and the other guy had me at 10%, I could sweep kick them, or use scorpion\'s harpoon/uppercut cheap over and over till they died. People tend to get really, really upset when you do that though.
