Rickson Gracie "on" dos Anjos v. Pettis

"The fundamentals of self-defense present in Jiu-Jitsu give you a clear notion of how to deal with your foe's specialty. I'm no great boxer, but I have a deep knowledge of how to clinch, how to avoid the right distance for punches. I'm no great kicker, either, but I know what a guy needs to kick me. Strikers must have a certain gentlemen's agreement to stay in that distance, for otherwise the referee stops the bout. That's evident, so my specialty is precisely not to give a striker whatever it is they need to strike me."

--Rickson Gracie, Rickson's Way, January 2006
