What happens when there is a tied score? And what is the Tie Break?

If two players in a group have the same score, both will advance.
 

Tournament Directors (and most do on Chess.com) can choose to use the Tie-Break method (we use the Neustadtl score method) which factors in the strength of the opponents.


Below is an example of a Group where the Tie-Break method is used.  You can see the top two players have the same Score; 8.5.  Using the Tie Break method now factors in the Tie Break points.  Player 1 has more Tie Break points so they have advanced.  Without the Tie Break, both players 1 and 2 would have advanced as they have the same Score.

If two players have the same score and the same Tie Break score, both will advance.


Here is an example from the same Tournament; both players 1 and 2 had the same Score and the same Tie Break; both advanced to the next Round:

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

Group # --     Bob Mary John 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.
