One of the most common offensive strategies is the vertical stack. In this strategy, a number of offensive players line up between the disc and the end zone they are attacking. From this position, players in the stack make cuts (sudden sprints, usually after throwing off the defender by a "fake" move the other way) into the space available, attempting to get open and receive the disc. The stack generally lines up in the middle of the field, thereby opening up two lanes along the sidelines for cuts, although a captain may occasionally call for the stack to line up closer to one sideline, leaving open just one larger cutting lane on the other side. Variations of the vertical stack include the Side Stack, where the stack is moved to a sideline and one player is isolated in the open space, and the Split Stack, where players are split between two stacks, one on either sideline. The Side Stack is most helpful in an end zone play where your players line up on one side of the end zone and the handler calls an "ISO" (isolation) using one of the player's names. This then signals for the rest of the players on your team to clear away from that one person in order for them to receive a pass. In vertical stack offenses, one player usually plays the role of 'dump', offering a reset option which sets up behind the player with the disc.
