CXR has rated well over 1000 tournaments and hundreds of thousands of games. Our players are your neighbors -- from Oklahoma, Missouri, Arkansas, and many other locations. We have been the official rating service of the Oklahoma Scholastic Chess Organization (OSCO) for more than ten years. Our "Alumni" include many GM's.

If you have been used to USCF service, prepare yourself for a giant step up. If you will take a few minutes to explore this website, you will see that CXR provides much, much, much more than any other rating authority. Plus, our ratings are recognized (for section placement) by, and closely track, USCF ratings.

If you run tournaments, CXR will save you a lot of time and drudge work. Plus, you don't need to run around asking people to pay for memberships or renewals. Let us show you how easy your life can be with CXR.

If you run a club, be aware that you'll be able to report non-tournament results for rating purposes, and there is no limit to the number of games you can report. There will be no fees, no cost. CXR is an international rating, and any out-of-state or Mexican players visiting your club can receive free CXR membership.

If your club or chess program serves players living in the area bounded by Route 35 on the west and Route 10 on the north, you are entitled to free service from CXR. This includes Brownsville (of course!), Laredo, San Antonio, Houston, Galveston, Beaumont, Orange, and Port Arthur. We will readily make exceptions outside of this area, if needed.
