The heartbeat of the side and arguably the most influential player on the pitch. Almost every attack will go through the fly half, who also has the responsibility of deciding when to pass the ball out to the centres and when to kick for position.
The fly half must orchestrate the team's back line, deciding what rehearsed moves to put into action and reacting to gaps in defence. He or she is also the main target for the defending team's open-side flanker and so must be strong in the tackle.
The fly half has to be able to relieve territorial pressure by kicking down the field into touch, and is often the team's designated place kicker for conversions, penalties and drop goal attempts.
In defence he or she will marshal the backs to ensure each opposition player is covered, and a strong-tackling fly half can snuff out opposition attacks before they start.
Tactical awareness, accurate passing, a good rugby brain, kicking accuracy, vision, leadership, resilience.
