Spoiler
We've got a huge positional advantage and a huge race advantage. And with his anchor we're definitely not too good to double. AtS, I'm inclined to wait until it's a cash to turn the cube, but while it doesn't seem to be a cash here, our race and positional advantage is too strong to sit on it any longer.
Double.
Not entirely sure about this one either.
