Set up in a box.
The player on the right (4) cuts in and the player on the left (3) cuts out. Either player can be thrown to if open.
Player 4 cuts out and player 3 cuts in basically switching spots. If one of them is open like 3 in this case they get the disc.
If no one gets the disc you can run the cut a second time. If 3 gets the disc 4 should continue down field and hopefully get the disc.
