Right or wrong, I'd open the club face and play it like a long greenside bunker shot. Not sure I'd beat myself up over the outcome regardless of how it turned out.
I had this lie a few years ago and hit it to 30 yds of the green 200yds out.The joys of the game!
I'd try a soft, open-faced, pitch and think about jarring it. I'd try to utilize the bounce by coming down on top of the bark. And I would arrange that suitable refreshment be provided, in due course, should success ensue.
