How to kick afl football on the run?

I need urgent help with kicking an afl football. i can kick fine while standing i.e accurately and directly. but under any sort of pressure and on the run, my kicks spin backwards too much and there isnt on them and they are up and under kicks. also, when i kick it on the run or under any sort of pressure, i notice that they hit the end of my boot. I desperatly need to know how to control the ball with you're hand on the run that is, how do u hold it? do u push down on the football?? what angle should the ball land on ur foot?? how to control the ball all the way to ur foot etc. Thanks.
