hi!
this is a technique im a bit confused on - want to try and clarify the mechaniques before i spend to much time doing it wrong

as i understand it there are two versions of the side kick - yoko geri kekomi and yoko geri keage which can be preformed from kibba dachi
again as i understand it
yoko geri kekomi - this kick is a side thrust kick, the knew comes out and the leg is "pushed" in a straight line towards the oponent with the energi traveling straight from the hip down through the leg and out through the heel into your target - the leg does not come back but you go straight back into stance. is this understanding correct?
now the one im mainly confused on is the keage
is this kick
1) the same mechanics as kekomi - but the kick is more of a snap rather than a thrust - the leg snaps out with speed and then snaps back to the original position before loweing back to stance
2) more of a mawashi geri type of kick, but straight from the front leg and without the hips circling around - i.e. the leg comes up a little bit offset from the target and the leg then snaps out in a similar manner to mawashi geri
3) none of the above?
