I'd likely raise the turn, call if 3-bet, call a river bet U/I, raise if improved (obviously).

Given that hero called the turn, is there anything wrong with simply calling the river, rather than raising? If 3-bet, it looks to me hero almost has to fold (is sb seriously 3-betting anything we beat?), but I'd likely call (though I'm not sure I raise the river U/I so the situation wouldn't even come up if I take my call down line).
