As you practice you should come up with a routine. Once you develop this routine you should always follow the same routine be it in practice or in a tournament. This way it becomes natural and reliable. Under the pressure of a tournament sometimes it is difficult to think but you can still draw some level of confidence knowing that if you go through your normal routine a ringer will be the result. When setting up a routine don't make it so long it becomes annoying and cumbersome. Under practice conditions you are not likely to follow it if it is too long, so it won't help you. Something simple but relevant is best.
