Versus vs. Versus

Note: This can be only achieved in the XBLA and ps3 versions,not in the Nintendo DS version (even though it also has Vs. mode).

Strategy
If your opponent is not here, just use your controller or his or her controller, then while you're using his or her controller, move to "Concede Match" and concede five times and your opponent will give you a win and you will get this achievement. Don't quit Versus Mode as you have a win, or your streaks will be reverted. If you are playing with someone, just persuade them to lose 5 times.
