2. Tournament Format:
• Tournament Format: Round-Robin
• Total Rounds: 3
• Round Times: 3:00 pm and Rounds 2 & 3 on a rolling schedule
• Time Control: G/30;d5 (Game in 30 minutes with a 5-second delay at each move.)
• Games will be US Chess regular and quick-rated (so-called dual-rated). Tournament results will be submitted immediately after the last round is finished.
• Players will be split into groups of four (quads) based on their ratings, from the highest-rated to the lowest-rated.
• If the last quad does not have four players, they will play a mini-Swiss tournament.
• Monthly supplemental OTB rating will be used. The Chief TD has the discretion to use a player's USCF online rating (ONL) or live rating for pairing purposes in extreme cases where fairness will be preserved by doing so.
3. Byes

4. Prize Fund -- $60 for each quad
| Quad | |
| 1st Place | $60 -- Winner takes it ALL! |
