Chasing
Chasing can be defined as traveling quickly to overtake or tag a fleeing person. In many game situations, the fleeing player is given a head start-he or she is allowed a time period to run away before the chaser can begin traveling. The fleeing player tries to avoid being caught or tagged. Thus, the chaser needs to able to run at full speed and to react quickly to changes in the direction of the travel of the fleeing player.
