I'm quite surprise to hear that
- to use your blocking arm (such as Tang Shou) to block your opponent's punch,
- re-direct his arm to be away from your attacking path,
- use his leading arm to jam his back arm (this is a very important MA strategy),
- you then attack him through his "side door",
are not part of the WC "bridge" strategy.
Well, look at your picture and tell me why that taan-sau is not simply a direct punch to the face rapidly followed by another from the right?
He's entering with the wrong leg, unnecessarily chasing an arm, and punching low when he could much more effectively finish the guy by just punching him in the face.
This is probably a commonly accepted WC technique, but it's bad, like most WC...
