You can make a little progress with a simple move. Where in column 7 can you place a 9?

After that you probably want to use a naked pair, which will require filling in all of the pencil marks to locate. Once you figure out the naked pair, it is easy enough.

Yes, you will need to fill in all the possibles. I didn't find much except for a naked pair, which let me at least eliminate some possibles. This is not an easy puzzle by any means, or I was missing something. At this point, I looked for hidden singles. Usually they are made naked by finding pairs and triples, but sometimes not as in this case. Found one that was made a hidden single because of the pair I previously found. Won't tell you which so as not to spoil all your fun unless you ask.
