Well kicks are very nice if you can use them effectively. Hence my 3 years of TKD. But anyway, in the situations I've been in usually a good shot to the solar plexes if he's not expecting it will end it if you know how to channel energy behind your blows. Also Noteable targets: Nose
Jaw
Side of the Neck (never in the adam's apple unless you want to kill him)
Floating Ribs



That should do ya.
