Cincinnati Chess Club periodically announces events run by other organizations. They will likely use differing methods from ours.

Swiss System Tournaments

These methods will be applied, in order, in Swiss System tournaments. In the event of multiple-way ties, at each step, if one or more participants would be eliminated, we will do so and take the remaining contenders into the next method.


If two (or more) players are tied, their head-to-head results will be the first tie break. If they drew or did not face each other, proceed to the next method. Ranking (plus or minus), not percentages, are used.

Solkoff System

The Solkoff system is the sum the final scores of each opponent a participant faced. All unplayed games are counted as half a point, regardless of the reason they weren't played, including zero- and full-point byes.
