Puzzle #78: White to Play; White to Tinue

Hello, all!

I had a lot of windshield time at work this week and decided that I wanted to beat TakticianBot. I came close a few times with flats, but Tako would ultimately outwit me. I finally got this road win and thought it would make a good puzzle.

For the purpose of this puzzle, Tinue is defined as a board state in which no matter what the opposing player does during their turn (Black, in this instance), a road win will be awarded to the other player (White) on their next turn. If you are familiar with Chess, Tinue is very similar to Checkmate.

This can go a few different ways.  So, try to find the best and longest defensive line that you can for Black.

Please form your answer with PTN or a link to your solution via ptn.ninja. Also, be sure to use the spoiler tag so as not to ruin it for later puzzle solvers.

UPDATE:  The Reddit site has updated and the newer version does not recognize the older spoiler tag - " [spoiler text](/spoiler) ". The new version has it's own spoiler tag " >! spoiler text !< ". Unfortunately, the new spoiler tag does not work on the old Reddit. So, for the time being, since we have community members using both new and old Reddit, both tags need to be used. I found a way to nest these spoiler tags:

>! [spoiler text](/spoiler) !<

Ex:  >![35. a3> 3b2+](/spoiler)!<


I know it's a bit of a pain, but eventually, we should be able to switch over to the new tag only.

Enjoy!!

P.S. If you have suggestions for puzzle board states, please let me know. If you would like to post them yourself but don't know how, I can also help with the behind-the-scenes steps.
