White to move is rather trivial, so must be black to move.

And this looks like ko.

What about just trying to connect back, seems like also ko?

But that means I'll have to go through other first moves to check for better results orz

In any case, I have a tax final tomorrow. Maybe I'll take another stab during the weekend.
