Judo, jiu-jitsu, gracie are good choices too

If you know kungfu, karate, kickboxing, full-contact or muay-thai, and a gracie-man is runing to catch you.

If you dont make a k.o. with one punch/kick he will throw you to the floor.
Then in the floor he will win.

The strategy of catch and throw, I think is the best strategy if you have only one opponent.

Well the vingtsun advantage is that whith less effort and less train you have too much efectiviness.
