Worth Grand Prix 16th October 2021

This was the second tournament in our grand prix series since the return to over the board chess, and a qualifying event for the prestigious London Junior Chess Championships in December. As such it attracted a field of just over 100 players, many from travelling from London and other Home Counties. The Under 18 section was particularly strong featuring several players who have represented England at chess.
