I agree i dont get it myself like you said how do you know
which technique 2 use and when all i can say is i wish i was that good.
Maybe practice one technique at a time. Get the hang of that and then practice the other technique.
As with everything, the more games you play the better you will get.... after awhile you will get to know which technique to use.
Very good tips and the pics and video make it better to understand than actually writing the whole process down in a post.
