Double elimination format:
Double elimination is a modern staple in computer game tournaments - including Starcraft, DotA2, LoL, and CS:GO.
The concept relies on the idea that every player must lose two matches to be eliminated.
In the Grand Final this extends to the player the upper bracket who is yet unbeaten. If they are beaten once it opens up a second match in the grand final.
This format ensures no flukes, and also gives players that are flying across the world a second chance to prove themselves.
