I reckon there may be a few people who have not played serious competitive chess for a while and returning to the game can be daunting. I had a year off and I've written about my return:

Some issues that might affect ones level of play on a return to chess:

- age
- length of break
- expectations
- degree of seriousness of the return

I'm in my late 40's, struggling to calculate like I once did, but am giving myself 3 months to try to find form.

Can others suggest ways to help players to return to competitive chess after a lay off?
