I dunno why everybody is focussing on the kicking and punching so much. The particular type of competition here allows (in fact as I understand the rules used, encourage) people to use clinching and throws to put their opponent down and/or off the mat whilst being careful not to have your balance taken so the other person can do it to you. I thought that was pretty Tai Chi ? (at least on the level that we can all see on a video). In my limited understanding, styles of Tai Chi other than Wudang teach striking methods. Now fair enough, these might involve palms or other ways of using the hand which you can't really do with a boxing glove on. But, these sorts of competitions formats allow you to try out so many things which are important, like your level of endurance, your speed, your ability to move in an evasive way into a good position, your ability to spot the moment when somebody's balance is vulnerable, smother strikes to 'clinch' and control the other persons movement all whilst they are helpfully doing their utmost to knock your block off, possibly using a style you have never encountered before etc.. I really don't see why they are seen as unhelpful to developing good Tai Chi. Now, the desire to practice the techniques which you can't do with boxing gloves on is fair enough, but if never using gloves meant that you didn't get to practice the above things at a high level of intensity, wouldn't that also be detrimental ? And if you can see the value of this type of thing, wouldn't it be unfair to judge people by the standards of the lighter practice done without gloves when they are in the much more frightening and intense situation of somebody (possibly somebody very well built from a completely different 'hard' style) trying to knock their block off ?
