Daily Puzzle #40.5 (Hard)

Tinuë - Black to play - Hard:

Thank you all for supporting me as I reach my 200th puzzle. It's a big milestone. To celebrate, I'd like to invite you all to post your favorite puzzle that I've made. I will select a few (it really depends on how many requests I get) and digitally sign them and send them to you as a DM to your Reddit account or to an email account of your choice.

As always, post comments in the r/Tak subreddit, using PTN and spoiler tags.
