Market Rasen man Lawrence Cook has faced the Mastermind black chair again - this time in the semi-final of the competition.
Lawrence won his heat of the top BBC quiz show last December to make his way through to the semi-final, which was aired last Friday.
Along with four other contestants, Lawrence faced 90 seconds on his specialist subject - the life and chess of Bobby Fischer - followed by two minutes on general knowledge.
After being the first to face quiz master John Humphrys in the specialist round, Lawrence lay in joint third spot at the end of the round, having scored seven points and no passes.
In the general knowledge round, Lawrence score 11 points and no passes to finish joint third on a very credible 18. The winning score was 21 and second place 20.
“I had one of the best experiences ever at Media City, Salford,” said Lawrence.
“I knew the competition would be very tough and so it proved, some of the nation’s quickest and brightest quizzers had got through.
“Coming third out of five was about par for the course and I was very pleased with my points total.
“I’m looking forward to seeing six contenders in the grand final this week.”
