When your opponent roundhouse kicks below your knee, if you
- shift your weight on that leg,
- turn your shin bone to meet his shin bone,
- before he lands his kicking leg, you use your back leg to "hook" his standing leg from inside, and
- push his upper body.
Since both of his legs are off the ground, he will fall. The window may be small but the opportunity is there if your timing is right.

Why haven't we ever seen this move used in any cage fight? Your thought?
