Pak Sao and Punch
The pak sao (I call it a press or smack) is an excellent technique for self defense. It can be used against a threat as in the above images, or against a straight punch (although techniques like the crash, which comes from the bong sao, are easier to apply). You can use a punch, palm, chop, hack, etc., with the pak sao.
The purpose of the pak sao is to smack or press your opponent's arm in and out of the way...jamming it...so that your opponent is unable to use it to hit you or defend against your attack.
Check out our Wing Chun trapping video for more tips on the pak sao.
