I emailed the Observer's crossword editor to find out why the Everyman was so much harder, and she replied:
The Everyman has become slightly more difficult, but not impossibly so. What happened is that Allan Scott, who set the Everyman for many years, retired at the end of March and so we have a new setter (recommended by Allan). At first I found I could hardly get any answers, but as the weeks went on I got more and more and started to enjoy it.
I could solve Allan's crosswords in about half an hour, but now it takes longer and I'm finding I prefer the greater challenge.
I think it's really a question of persevering until you get the hang of it.
With best wishes,
