I've solved the puzzle at http://www.sudoku.org.uk/WeeklySudoku.asp but had to resort to trial-and-error after a certain point. Can anyone tell me what advance strategies are used to finish it?

Also, I haven't posted on here before so don't know how to create the puzzle display yet. Will study up on that...
