For the pot/stack ratio on the turn, I go allin. Get him to put his money in when drawing or dead. How can a check-raise make you sick when your bet is allin? There's over 60 in pot and you have about 20 left.

I'm sure there's a depth of money where I generally check turn, and your reasoning for it is a good one, but this isn't it if I read your post right.

There is also situations where I consider not raising the flop, but that is more dynamics specific.
