I found an awesome MMA training video of Pat Barry demonstrating a fighting trick on Matt Mitrione. He basically sets up for a big left hook but misses with the left hook on purpose and as Mitrione winds up a left hook, he snap kicks him in the head with his lead leg. Really great insight courtesy of TapouT VTC. It's tricks like this that separate the good from the great. It's impossible to succeed if you're predictable these days.
