In addition, Suffolk-born twins Nick and Richard Pert are 7th and 26th respectively (2564 / 2443). And the other pair of identical twins, Tom and Adam Eckersley-Waites (94th and 95th) were members of the Bury Knights Junior Chess Club for a couple of years between 1994 and 1996.
Justin Tan (2361) is of course Australian, so doesn't feature in the English list. If he did, he would be in 50th place.
Adam Hunt's 'replacement' at Woodbridge School a couple of years ago, Stephen Gordon, is 13th at 2497.
So that's a total of ten players with close links to Suffolk.
