Nicely made video.
Some observations:
1) These guys probably also do kung fu and MMA/grappling/San Da of some kind - you can tell from the dojo! They're training hard and seriously.
2) I quite like the emphasis on feeling - bang on.
3) The dude correctly identifies that push hands competitions are very very similar to Sumo. And if you're good at Sumo then you should be good at this.
4) Fascinating insight into teaching - the dude seems to do a few things that are "wrong" according to Tai Chi, but are working (i.e. sticking his butt out and leaning forward) however, he gets corrected by the instructor to stop doing that - I just find that interesting. The "Stop cheating, it makes you win!" mentality is rife all over the Tai Chi world. One of the reasons I avoid push hands with people unless the conditions are right (i.e they are the right sort of person). I much prefer the "Hey, if it works, then it works! - it's up to you to figure out what I'm doing and stop me" mentality of BJJ.
5) In the end, the better wrestler would win that exchange (where they are doing the 'foot outside the square' push hands). Learn some wrestling
6) I really like this coach - he's clearly skilled, but competitive push hands is the problem - even this coach gets super tense when under pressure because of the needs to win. I just think that it's better as a training exercise for learning TCC skills - when it gets competitive, it all goes out the window (unless you are very, very very very good).
