It'll be a donkfest from the first hand. Be a smart donk that goes nuts trying to build a stack, just don't be a total idiot about it. I would expect about 1/3 of the field to be gone after the first hour so to be ahead of the curve you've got to have at least doubled up by then. You'll need some padding since the 20 minute rounds will just get more and more difficult to play.
