Then catch the huck if you get it, or wait until the next throw happens. Turn around right as that throw goes, so you will be open running in towards the disc right when the person with the disc looks downfield for a receiver. This can also work in the reverse direction. If you don't get open cutting in, turn around and run deep. Again, with good timing you could be open deep just at the point when the next catch is made and the receiver is looking downfield.
Cuts can also be useful in distracting the defense to help other cuts get open.
I often make cuts against the force to give the marker something to worry about. This can make it easier for the thrower to get off a good throw with the force or up the middle. This is an advanced technique which is one of my favorites because you get to mess with your defender's head. As I mentioned above I usually get front guarded with my defender looking at me. This means that they don't always have firsthand information about where the disc is.
