http://www.chess.com/tournaments/help.html#tiebreak
Multiply your individual score against each opponent by that opponent's total score. Add up all these for each opponent.
For the example in the help.
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 |
Bob vs Mary: 1 times 1.5 = 1.5
Bob vs John: 2 times 1.5 = 3.0
Bob's tiebreak = 1.5 + 3.0 = 4.5
