Direction: 16 players participated in world Chess Championship. These 16 players are seeded from seed 1 to seed 16 with seed 1 as the best rank. These 16 players are divided in two groups such that all the odd numbered seed are in group A and all the even numbered seed are in group B.
In each group each team plays with each other exactly once and no match ended in a tie. For a win winner awarded 2 points while looser 0 points. From each group top two players based on the points scored are advanced to the next stage i.e semifinal stage. In semifinal stage top scorer of one group plays with 2nd best scorer of the other group. Winners of the semi-final play for the final while loosers play for the 3rd place.
An Upset is when a lower seeded player beat a higher seeded player.
In case of same number of points at the end of the 1st stage there is a complex tie breaker rule which is used to determine the rank.
