What is a tie break?

Tie break scores are used in the event that two members finish in a tournament with the same score.
 

Below is an example of how the tie breaking system works:
 

Group # --    

1

2

3

Points      

Tie Break   

1. Bob

X        

0 1      

1 1     

3         

4.5

2. Mary

0 1

X

0 0.5

1.5

3.75

3. John

0 0

0.5 1

X

1.5

2.25


A player's tiebreak score is calculated by adding the sum of the player's points they have defeated to half the sum of the player's points they have drawn against.
 

Bob won one game against Mary and two games against John. So Bob gets 1x1.5 points from Mary and 2 x 1.5 points from John, which sums up to 4.5 tiebreak points.
 

Mary won one game against Bob and drew one game against John. So Mary gets 1x3.0 points from Bob and 0.5x1.5 points from John, which sums up to 3.75 tiebreak points.
 

John won one game and drew one game against Mary. So John gets 1.5x1.5 points from Mary, which sums up to 2.25 tiebreak points.
