Chess prodigy Samuel Sevian, 13, is America's youngest ever grandmaster
Aged just 13, prodigy shatters record to become country's youngest grandmaster
Not many people can claim to have shattered a major American record at a mere 13 years, 10 months and 27 days.
But chess prodigy Samuel Sevian can now do just that after being crowned the country's youngest-ever grandmaster, beating the previous record holder by more than a year.
Sevian won all four of his games to push his World Chess Federation rating past 2,500 points - enough to secure grandmaster status - at a tournament in St Louis.
"I feel really good and somewhat relieved. This was one of my best tournament performances," the teen said, noting he had beaten three grandmasters during the event in only 20-25 moves.
His father Armen - a scientist born and raised in Armenia who later emigrated to the United States - is bursting with pride.
"He really outplayed his opponents in three games. But the fourth, it was really back and forth, it wasn't clear," he said.
