sounds like you gave the perp a reason to go back to school, as wel as educating him on how hard a book can feel. I also agree with everyone you were very lucky this guy was soloing and you caught him off guard..

I always have ot go for the 3 main points if I get into a fight and it not a knife deal, knees eyes and throat cause if they can't see you, chase you or breath then you can get away. I always like the refence in a comic book ( ghost rider cross over ) were blaze tells ketch that in a fight that last more than 30 seconds you done lost. and anything goes.
