Knights were battling bishops as kings and queens watched on at Scarborough Spa.
But this was no medieval battle, this was the 37th annual Scarborough Chess Congress.
Close to 350 players of all abilities turned up to pit their wits against each other in a true battle of skill and strategy.
The Spa Ocean room was packed and the sound of silent thought was deafening.
Andrew Butterworth, treasurer of Scarborough Chess Congress, said the tournament had been a success.
He said: “It went very well and there was some fierce competition.
“The Spa were very helpful as always and it meant that the congress was a great success again.”
This year’s top prize was shared between Danny Gormally and Laurence Webb, who finished level on points after the competition.
That means that they split £750 for the top prize.
