Mixed Doubles Bonus Prizes

The mixed doubles bonus goes to the best male-female two-player team by combined score across all sections. The team must average under 2200, players may compete in different sections or schedules, and registration closes before both players begin Round 2. Unrated prize limits also apply: USD 150 in Under 1000, USD 250 in Under 1300, USD 350 in Under 1500, USD 500 in Under 1700, and USD 700 in Under 1900. Any remaining balance from a limited prize goes to the next eligible player.

⏱️ Time Control & Pairings

The tournament uses a 6-round Swiss system with two schedule choices. First, the regular 3-day schedule follows 40 moves in 80 minutes, then sudden death in 30 minutes, with a 30-second delay. That gives players a full long-play format with enough room for deeper calculation and more serious endgame play.

Meanwhile, the 2-day option accelerates the first half of the tournament. In that schedule, Rounds 1 through 3 use G/35 with a 10-second delay before the event merges into the standard timetable. In addition, players may take up to two half-point byes in any round, although they must commit before Round 3. August official ratings are used, and unofficial or Online Regular ratings are usually applied if a player would otherwise be unrated. The event also notes that players may not enter below USCF Online Regular Rating minus 100 points.
