Thanks sjs - I've tried filthy and flitch everywhere on the board I can think of but unable to get 54. Just wondered if anyone had managed to do it - don't particularly want the answer as I won it 2 weeks ago so am probably on a list of people who shouldn't win for at least a year!
Thanks RobO. I'm almost at the point of giving up and putting my Scrabble set away, but I'll try HEFTILY around the board before I do. I have tried across to the RH triple, starting with I to make IVIED, but ITCHY doesn't make enough.
