& the Carter County Open

May 11, 2024

Lake Murray Lodge

3323 Lodge Road in Ardmore, Oklahoma map

The Red River Shootout (RRSO) is an annual team match between Texas and Oklahoma. Players are matched with an opponent of similar rating for two games (one as black, one as white).  Read about the tournament's history and notable players here.

Format: two games (one as black, one as white)


Time control: G/80;+5

Eligibility: To be eligible for the RRSO, players must have

  • an established regular rating

  • a current US Chess membership

  • Texas or Oklahoma as their state affiliation

The Carter County Open welcomes any player with a current US Chess rating—new/provisional players may participate, and no particular state affiliation is required. Most Oklahoma/Texas players who aren't paired with an opponent in the RRSO choose to stick around and play in this event.


Format: Four rounds, Swiss, game/30 with a five-second delay.

After check-in, we will pair as many eligible players as we can with a similarly-rated (usually within 50 points) opponent from the other side of the Red River. We hope everyone who wants to play in the RRSO will be able to, but it all depends on who shows up to play. If you do not get an opponent in the RRSO, or if you're from a state other than Oklahoma or Texas, or if you're a new player, we'll put you in the Carter County Open.

Schedule for both events:

9:00–9:45 check in

10:00 team photos

10:30 round one

Lunch break after round one

2:30 round two

Carter County Open rounds 3 & 4 will begin ASAP following the last game of the previous round.

Players are encouraged to come early and stay late to enjoy a hike, rent a boat or jet ski, or just relax and enjoy the view of crystal clear, spring-fed Lake Murray. We'll post cabin and room rates here soon, so check back or just give the Lodge a call at (580) 223-6600.
