Biography & Pedagogy
Travis Carney is a chess educator and the founder of Control The Center. With over two decades of competitive play and online coaching, Travis specializes in translating dry, encyclopedic chess theory into digestible, interactive, and visually engaging lessons.
His pedagogical philosophy focuses on conceptual understanding rather than rote memorization. Through Control The Center, he aims to build a modern encyclopedia that helps beginners develop intuition, understand the "why" behind moves, and learn the game interactively.
"Chess is often taught as a series of coordinates and dry lines," Travis says. "But beginners learn best when they can see the ideas flow on the board. My goal is to combine the aesthetic beauty of the game with interactive clarity so that anyone can learn to control the center."
