Good morning Zardoz - forget the scrabble tiles. There's a very good anagram facility on Chambers Word Wizards web site. It gave 1 ac at the start. Do try it.
Thank you AJH, AJT, & sudokulover for the tips. Tried the anagram links. Wow! That makes life easier, though it does feel a bit like cheating. Can usually do 8 letters in my head, but 14 -- ugh!
