⏱️ Time Control & Pairings
The tournament uses a Swiss System, although the number of rounds and time control depend on the section.
The Open section plays three games at G/80; d10. Therefore, each player receives 80 minutes for the game with a 10-second delay per move.
The U1600, U1200, and U800 sections play four rounds at G/45; d5. Each player receives 45 minutes with a five-second delay per move.
All sections count for US Chess rating. In addition, the Open section counts for FIDE Classical rating, so Open players must have a FIDE ID.
| Section | Rounds | Time Control | Rating |
|---|---|---|---|
| Open | 3 | G/80; d10 | US Chess + FIDE Classical |
| U1600 | 4 | G/45; d5 | US Chess |
| U1200 | 4 | G/45; d5 | US Chess |
| U800 | 4 | G/45; d5 | US Chess |
💰 Prize Fund
The organizers advertise a $600 projected prize fund based on 80 paid entries. At least 50% of the advertised fund is guaranteed, so the total cash prizes will not fall below $300.
If participation differs from 80 paid entries, the organizers may adjust the prize fund proportionally. Moreover, cash prizes are divided equally among tied players.
| Section | 1st Place | 2nd Place | 3rd Place |
|---|---|---|---|
| Open | $125 | $85 | $60 |
| U1600 | $50 | $35 | $25 |
| U1200 | $50 | $35 | $25 |
| U800 | $50 | $35 | $25 |
In addition to the cash prizes, the top three players in every section receive trophies.

The tournament offers four sections.
| Section | Eligibility |

| U1200 | US Chess rating 700–1199 |
