Frank Maguire learned how to play chess when he was in 8th grade and didn't keep the game to himself. The 90-year-old taught his son, Mike, how to play when Mike was 10-years-old.
"When he taught me to play chess he just thought he was having fun with his son, sharing a challenging game," says Mike.
But that one game turned into much more. Mike grew up to become a chess coach. He has four teams in Indiana, teaching more than 2,000 children the rules of the game and it all started in his family's home in 1966.
"I thought 'wow, that is really something,'" says Frank, when he learned about how many children his son has taught. "It's a big contest between the two people."
A contest that this father and son duo still play.
"It means everything for dad and it's because we have this fun game that we play together," says Mike.
