as, half-back and first five-eighth respectively. The fly-half is crucial to a team's game plan, orchestrating the team's performance. They are usually the first to receive the ball from the scrum-half following a breakdown, lineout, or scrum, and need to be decisive with what actions to take and be effective at communicating with the outside backs. Many fly-halves are also their team's goal kickers. The scrum-half is the link between the forwards and the backs. They receive the ball from the lineout and remove the ball from the back of the scrum, usually passing it to the fly-half. They also feed the scrum and sometimes have to act as a fourth loose forward. Three-quarters There are four three quarter positions: two centres (inside and outside) and two wings (left and right), the inside centre is commonly referred to as the second five-eighth in the Southern Hemisphere. The centres will attempt to tackle attacking players; whilst in attack, they should employ speed and strength to breach opposition defences. The wings are generally positioned on the outside of the backline. Their primary function is to finish off moves and score tries. Wings are usually the fastest players in the team and are elusive runners who use their speed to avoid tackles. Full-back The full-back is normally positioned several metres behind the back line. They often field opposition kicks and are usually the last line of defence should an opponent break through the back line. Two of the most important attributes of a good full-back are dependable catching skills and a good kicking game. Laws and gameplay Scoring Rugby union is played between two teams – the one that scores more points wins the game. Points can be scored in several ways: a try, scored by grounding the ball in the in-goal area (between the goal line and the dead-ball line), is worth 5 points and a subsequent conversion kick scores 2 points; a successful penalty kick or a drop goal each score 3 points. The values of each of these scoring methods have been changed over the years. Playing field According to World Rugby's Laws of the Game, a typical rugby ground, formally known as the "playing enclosure", is formed by two major zones: The "playing area", which includes the "field of play" and the two "in-goals", and The "perimeter area", a clear space, free of obstructions such as fences and other
