Let's face it; the problem comes down to lack of interest NOT by the children, but by adult chess players. A junior chess club in a town the size of Ipswich is perfectly viable. It just needs someone with that spark of enthusiasm to get it going.
One of Ipswich's best juniors, currently, is 11-year old Alex Sheerin (graded 121). And where does he come to play chess every Friday evening? All the way to the Bury Knights. It's crazy: he should be able to go to a junior club in his home town, rather than have to make a weekly 50-mile round trip.
So here's a challenge to Ipswich-based adult chess players. If you want chess to survive in your town, get the Junior Club up and running again. Don't leave it to others; stand up and do something about it!
By the way, the club's website is still active, although the information there is way out of date.
