Tournament forms are all about the details. Check out this video of Rika Usami (a world tournament forms champion). She’s doing Kosokun Dai. She does a few of the moves slightly differently than in our Seito Shito-ryu Karate version, but that’s not important for now.
What is important is to watch her presence in the ring and sense of timing. This is a form that is performed at a very high level, with 100% attention to detail. Nothing is out of place and there is no wasted motion. She is totally focused on her imaginary opponents, and you can tell that she’s winning the imaginary fight.
