Suggestion to Solve (re: Stuck) contributed by Lynne

The key square to look at is Gd. There seem to be only two possibilities 5 or 9.

But the 9 can not go there. In Ad only 3 and 9 are possible, but this also the case for Ed. This is an example of a 'naked' twin (see strategy page) so both 3 and 9 can not possibly go elsewhere in column d. So that means Gd must be a 5.

There is also the Sudoku stripe to look out for. In this puzzle it is located in row F in reverse order. That should certainly get the puzzle sorted.
