Amazing range control. Really. Watch it again, and watch how he is almost always within range for the technique he is going to use, and almost always not in range at the time the other person throws their technique. (You should also watch the Sakuraba video on Wim's blog post, simply because he is a fun, fun fighter to watch.)
Next up---fast forward through about the first half of the first video shown below (the fight WILL eventually start), then watch the rest of it, and then the second video. Now, I am not a Muay Thai fighter, nor a ring fighter, so bear in mind I'm not saying I could beat the Japanese guy or anything---but what person put those two people in the ring together?! Seriously. Saenchai controls the fight almost completely. And watch how he does it---when he wants to kick, he does. When he is tired of that, he punches. When he wants a break, he takes one. In the entire fight, there are very, very few choices that are made by his opponent.
Saenchai vs Takemura Part 1
Saenchai vs Takemura Part 2
This isn't meant to be any sort of criticism of Takemura, by the way. He is just outclassed, and really, really got lucky that Saenchai doesn't seem to be the type of fighter who needs to destroy his opponents to prove anything.
Why am I talking about pro Muay Thai fighters on a Hapkido/Self-defense blog? Watch Saenchai's movement, timing, and structure---he is almost always where he needs to be for the technique he wants to perform at the time at which he can apply it.
That kind of timing/range control is worth watching.
