Like many 8-year-olds, Ashwath Kaushik likes bike riding, LEGO, and hanging out with his friends. He also likes chess—and he’s really good at it. On February 18, Ashwath became the youngest person ever to defeat a chess grandmaster.

In the game of chess, grandmasters are considered the very best. It’s not easy to defeat one. Ashwath’s victory opposite grandmaster Jacek Stopa, 37, took place at a chess tournament in Switzerland. Only one other 8-year-old had defeated a grandmaster before, and he was five months older than Ashwath.

“I feel proud of my game and how I played. I felt amazing, just unbelievable,” Ashwath told CNN.

Ashwath started playing chess when he was 4 years old. He learned the game with help from a website called ChessKid. Before long, he was playing on a chess board against family members and winning. Today, Ashwath has a chess coach and some big dreams. What’s his goal?

“[I want to be] a world champion,” he told CNN. “That will be a bit of time. It won’t come quickly.”

“I practice a lot each day,” Ashwath said. “A lot of children have a natural talent, so I think I’ve got a natural talent at chess.”
