Vikings: I am going to push back on that, because at the very least it seems misleading or confusing, if not just plain wrong.

S-B is a tiebreaker system. If you win four games and tie one game, then the tournament table will say that you have "4.5 points".

There is also a column labeled "S-B". If someone else also has 4.5 points, this method will decide which of you wins the tournament, or sometimes the tournament will be a tie if both of your S-B scores are the same.

Your S-B is decided by the number of games your collective opponents have won. If you play against players A,B,C,D, and E, and player A won 3 games, and players B and C won 2 games each, and players D and E won 1 point each, then your S-B score is 9. If the player you are tied with under the "points" column has a higher S-B than you, then s/he wins the tournament at BrainKing. If you have a higher S-B, then you win the tournament. If you have the same S-B, then you both win the tournament.

One can argue that this makes sense, or not, but it is how things work here. If nothing else, everyone plays under the same system.
