What were you and your opponent wearing? There were a lot of matches - 40+ - and I had to keep going over to the Grand Champion finals, push hands, Chin Woo, etc. in the other room, so I missed a lot. But I think I remember a fight that went akin to what you describe. You got to understand - I see fights through a camera lens now, so it makes them a little surreal to follow sometimes.
There was no video permitted in the Sanshou, only the official one from Taiji Legacy. They were pretty vigilant about shutting down videotapers.
