Do you know your off-loads from your collisions? What about the difference between a ruck and a maul?
How are you at understanding what makes a good three-quarter over a standout half-back? And that’s before we get on to discussing locks, props, flankers and finishers.
Whether you're a rugby nut or a casual fan, the ninth Rugby World Cup will soon become must-see breakfast and morning entertainment.
The tournament, held in Japan, promises to be one of the most open yet.
So here’s everything you need to know about who’s playing who, when, where and how you can get to see the action – all of which is live across ITV - and how to catch up if you're not a morning person.
When does it all kick-off?
The World Cup opening ceremony is on from 10.30am UK-time on Friday, 20 September, followed by the opening game kicking off at 11.45am, as hosts Japan take on Russia.

What are they playing for?
The Webb Ellis Cup is the prize they're all chasing.
It's named after William Webb Ellis, who is credited with 'picking up the ball and running with it' while at Rugby School in the 1820s and thus "invented" rugby.
The account has been questioned by historians since, but his name remains on the trophy, which measures 38cm tall, weighs 4.5kg and is gilded silver.
New Zealand are the most successful nation, having lifted the world crown on three occasions.
England's only triumph was in 2003.
