Turn: I think it's fine to put in the massive overbet. These opponents like to trap themselves into calling off their whole stack.
I don't bother putting it all in, as it can all go in next card.

River: Folding would be criminal. I'm pretty sure you're beat, but I'm also pretty sure that you'll do badly with 150 chips.
On average, although you'll certainly sometimes come back from 150 chips to win the tourney, you'll also certainly win this pot more often than you would imagine.
I think it's an easy crying call.
