2, 11 and 26 for the asks :)
2. Do you plan each chapter ahead or write as you go?
I don't have many multichapters that were conceived as such, but I do have a few fics that became multi-part/chapter after I'd written the first part, and... whether I've planned it in advanced or realized it's going to be a multichapter, what I try to do is come up with a big picture outline of the story - part 1 was this, so part 2 will be this, and part 3 that, and I add to that skeleton as I write. So mostly I write as I go, but I try to give myself some bones to work with.
11. Link your three favorite fics right now
I assume this means ongoing multichapters? I'm reading so little fic right now, and have always been terrible about reading mcs (spend too much time on my computer already, reading that much text from it feels uncomfortable, etc), but I am keeping up with @lajulie24's One half won't do and A girl in trouble, and Six nights from @hanxleia
26. Which of your fics would you call your wildest ride?
Proooobably Night at the Grand Regent Hotel, aka my one and only sex pollen fic 🙈
