Circlestrafing.
In video games, particularly in first-person shooters, circlestrafing is the technique of moving around a target in a circle while facing it. It allows a player to fire continuously at a target while simultaneously dodging attacks.
In this diagram, the blue player circlestrafes around his red adversary, firing continually as he does so. Red, unable to keep track of the moving blue, misses with most shots. Blue will prevail.Photo credit: Fredrik
