Worksop College staged the annual Prep Schools Chess Championships.
More than 50 pupils took part in the event held in the grand setting of Churchill Hall.
Young chess players faced tough competition as they put their mind skills to the test to win the silverware.
David Welch, chief arbiter of the English Chess Federation, was warmly welcomed to score and oversee the event.
Mr Welch has more than three decades of experience organising junior chess matches and continues to organise international events, which attract thousands.
The Elms (Trent College Junior School) took home the silverware in the U11 category and Kings Grantham were the U13 winners.
Ranby House were proud to have the only two girls in the competition.
Patricia Quinlan, teacher in charge of chess at Worksop College Preparatory School, Ranby House, said: “Playing chess develops a child’s thinking and analytical skills as they decide which move to make next.”
“It is a fun game which we are pleased to encourage at Ranby House..”
“The pupils thoroughly enjoyed themselves and it was great to see them put their skills into practice.”
