most popular throws are backhand, and forehand/flick and less frequently, hammer and scoober, push-passes, and weak-handed throws (typically lefties). Part of the area of ultimate where skill and strategy meet is a player's capacity to plot and execute on throwing and passing to outrun another team, which is colloquially known as "being a deep threat". For example, multiple throwing techniques and the ability to pass the disc before the defense has had a chance to reset helps increase a player or team's threat level, and merging that with speed and coordinated plays can form a phalanx that is hard for competitors to overcome. When referencing the curve of a throw, the terms outside-in (OI) and inside-out (IO) are used. An OI throw is one that curves in towards the opposite side of the throwers body from which it is thrown. An IO throw is one that curves toward the same side of the throwers body from which it is thrown. With the rotation of the disc in mind, an IO throw has the side of the disc rotating toward the direction of the throw angled to the ground, whereas an OI throw has the side of the disc rotating toward the thrower angled to the ground. IO throws are generally the more difficult throw, and are very useful for breaking the mark. Apart from these formal strategies, there is also a freestyle practice, where players throw and catch with fewer limitations, in order to advance their ultimate handling skills. Strategy and tactics Offense Teams can employ many different offensive strategies, each with distinct goals. Most basic strategies are an attempt to create open space (e.g. lanes) on the field in which the thrower and receiver can complete a pass. Organized teams assign positions to the players based on their specific strengths. Designated throwers are called handlers and designated receivers are called cutters. The amount of autonomy or overlap between these positions depends on the make-up of the team. Many advanced teams develop variations on the basic offenses to take advantage of the strengths of specific players. Frequently, these offenses are meant to isolate a few key players in one-on-one situations, allowing them to take advantage of mismatches, while the others play a supporting role. Handlers and cutters In most settings, there are a few "handlers" which are the players positioned around the disc. Their task is to distribute the disc
