If the check-raise ends the hand, that's fine - maybe you got a PSB out of him you wouldn't have gotten if you hadn't checked. But not even donkeys stack off with mid-PP when a monochrome ace-high flop comes, even if you check the flop to them.

If the check-raise doesn't work, then I think you almost have to be up against a made flush, a set, or at least top two. You have crazy outs against all of those hands, but you're only ahead of his not-felting range. (If all the money goes in, you can expect to start out behind.)
