Sections 

The tournament has one section.

Swiss System

The tournament uses the Swiss System. This system is similar to a bracket system, but a player is never eliminated - they keep moving on to new brackets. Someone who wins and then loses is in the same bracket as someone who loses and then wiins. So, like a standard bracket, divide the "point group" into two, and the upper half plays the lower half.

One difference between the Swiss System and brackets that many people are used to, is that the lower half of a group is not inverted.

For example, in the first round of a ten-player Swiss System, player #1 plays player #6, not player #10 

Players are seeded based on their US Chess ratings. Unrated players are placed in alphabetical order following the rated players.

Number of Rounds

Four. Each player is guaranteed four games (unless they receive a bye.) We will work to provide a "house game" for any bye rounds.

Time Controls & Schedule

Time Control

G/30; d5

Round Schedule

Round 1 at 1:30. Rounds played as soon as possible. Based on the actual registrations, this is close to one hour between game start times. We anticipate conclusion around 5:30

 

It is possible to skip some of the games if you have a conflict during the day. However, there are some rules around this procedure. Remember for the following context, wins equal 1-point, draws (ties) equal ½-point, and a loss is 0-points.

A bye is a scheduled, unplayed game.  If a player receives a bye due to an odd number of players, they will get a free point. However, in many events, including this one, a player can schedule an unplayed game and receive a ½-point bye.

In this tournament, a player may schedule up to two ½-point byes. Although byes may be scheduled for any round, for fairness, the timing of this schedule must happen while the tournament outcome is still unpredictable. So they must schedule the bye before the end of round 2. Once round 2 is completed, no byes may be added or rescinded. Note that since there isn't a precise round schedule, any half-point byes must be carefully scheduled. To schedule byes, you'll just have to make your best guess. If you guess wrong, you may still have a 0-point bye for any missed rounds.

Byes may be scheduled online during registration or at the tournament site before the end of round 2 by going to Chess Central.

Tournament Check-in

No tournament check-in at the site is needed. Just verify your registration online before the tournament. If there are issues with a chess membership, please use the change/correction procedure (below) to make changes.
