OFC Tournaments: How They Work
You can think of it like a game of H/L games. You might be able to win the high pot, but if that is a split pot and you then go on to lose the low pot, you end up a lot worse than when you began the hand.
This pattern follows through to the end of the tournament and although it may seem strange at first, it is very easy and almost natural once you get into the swing of it. My advice to any poker player who has plenty of experience in standard poker tournaments is just to get a brief of the rules and structure and then jump in. There is no better way to learn the game than to play it, and providing you understand the game itself then the rest should be simple.
