if you look at people like Tomaz Barada (my main example:P) the sidekick is his main weapon in both tkd and kickboxing! it is great to keep distance and to 'tease' but if done correct it can have a lot of power too.. that little guy 65kg's or so.. kicked me harder than most big guys ever did. And the sidekick is fast, when i trained tkd I did 67 hard sidekicks in 30 seconds (ofcourse, not HARDEST.. but pretty hard) and what i found to be one of the secrets is to throw the heel up first..

that may be stupid, but for me it worked.
