It would depend on the opponent, but against a non-scientific fighter* my most effective tech is to draw his meaty right hand before using an open hand strike to the collarbone. *a guy who just tries to punch you in the face, ie most guys. If the guy had a knife i would use the most effective leg technique there is, the Run Like the Wind strategy. Next time you are sparring, get your partner to use a marker pen (soft felt tip please!)as a 'knife'. After a minute or two of sparring see how many ink marks you have on you and then think about how bad the injuries would have been. Just something to think about guys.
