I don't hate the river raise, but his sizing is pretty scary to me. Small donk on flop, and then turn and then whamm strong on river feels boatish to me. If he would have bet like $2.25-50ish I would feel more comfortable raising the river here.

If you're capable of raise/folding to a shove, then I still don't mind the raise. Unfortunately I feel like we often raise/call and lose in this spot out of stubbornness, which probably eats into the EV of the raise in the first place.
