In this vid:

we see the face being hit to "impede" the Right Punch/Attack. This seems to have some similarity to WC. The only problem I see is that there is no insurance on that Right Attack.

Personally, I wouldn't feel comfortable with this and would rather cover up or jam that Right Attack.

Thoughts from a WC perspective?
