The same could be said for defence against roundhouse kicks, crescent kicks etc. We don’t train them, but can defend against them
You are speaking for yourself here. IMO If you never see a good roundhouse kick, axe kick or whatever, you never learn to deal with the dynamics of what they are really like. If all your classmates throw crap roundhouse kicks or hooks, you’ll get good at dealing with crap roundhouse kicks and hooks, but when someone really good at them comes along, you’ll get hammered by something you haven’t seen. If you really think your ability to handle the crappy haymaker your classmate throws is going to prepare you to deal with a proper hook thrown by a trained boxer (and I accept that some posters know boxing), I’d be making sure my medical insurance was at the top level.
My Sifu has a kicking arsenal better than 98% of the TKD BB’s out there. He also had over 100 pro and amateur kickboxing fights winning many with head kick KO’s. We train roundhouse, side, hook kicks day in day out, as well as hooks, shovels, uppercuts, knees, elbows, headbutts, etc. If we’re contending with a round kick from a classmate, we KNOW it’s got some real sting in it.
I’ve noticed a tendency amongst many WC guys to fight with the head up, exposing the chin, because they’re trying to watch both theirs and the opponent’s hands. People with a slack pak sao often tend to try and bat the lead elbow of the jab down to the blind side, which is a perfect setup for the opp to circle over the block and lead hook straight off the jab, which works even better if the pak sao guy also has his chin stuck out. Or even just follow up with a second jab to the outside of the pak sao.
Don’t even get me started on what happens if the WC guy gets taken off his feet.
It’s very dangerous to be complacent about Wing Chun because of the alleged mechanical efficiency. Straight line techs are faster than circular, but few boxers or circular kickers will lead with such a tech, they’ll try to set you up first. And your “fast” straight punch may be slower than his “slow” hook. Unless you train HARD.
The classic WC demo is a hapless straw man TKD BB throwing a single big roundhouse or spin hook kick at the WC hero’s head, the WC hero “easily” countering this with a low side or stomp kick to the knee, thus “proving” the superiority of WC.
BOOLSHEEIT. a good kicker is going to set up a big kick like that with his hands, and use deception and feints to set it up. The game is somewhat different then.
I still believe good WC will match it with anything else out there. But IMO ordinary or crap WC is much worse than ordinary or crap boxing or kickboxing.
Complacency in your training could be fatal.
