I thought I would share with you one of my (current) favourite tournament entry techniques. The Flying Hook Kick.
Shoot out what appears to be a flying right side kick to the right of your opponent's head, approximately above his right shoulder. Whilst in mid-air, change the direction and snap in a hook kick to his head.
If it misses, because he is a "runner", add on a Dollyo Chagi to get him as he counters.
If it hits (and it usually does (either by scoring or was blocked)), use the rebound from the contact to put in either a left back kick, or a left spinning back kick.
It is a very intimidating kick when performed with speed, fluidity and without telegraphing.
Go on, try it and have fun.
