Default a partial sudoku puzzle

Hi MersenneForum,

I picked up a Sudoku book today and tried again at a puzzle that had stumped me before. I was able to put in the number 8 near the center and then I was again stumped.

I know there are some advanced Sudoku techniques out there, on the internet. Can anyone tell me a next step ( with logic) for the attached puzzle?

Also the possibility of a machine solver has been considered. This is from the "New York Post Bloom Sudoku Book" (fiendish puzzles c 2013). I am stuck on page 31.

I do not want to 'reverse engineer' the puzzle by looking in the answer section.

Regards,
Matt
