Hi Cec,
In response to your posts, since ngalbraith had not posted the grid he was stuck on between your first post and my first post in this thread, (a difference of 2 days). So I thought it a good idea to help him with new techniques that might solve this mystery puzzle, so he could post the puzzle and know what we mean when we say 'naked pair' or 'hidden triple'
Didn't mean to cause any confusion, only curious as to what tricks need to be used to solve puzzle 85367.
ngalbraith, could you post the puzzle please.
