Actually, I do all the time so I advise from bitter experience. The thing is, if your opponent is thinking, what hand that can stand calling a push checks that flop and then bets turn and river? A big queen with no spades and not much else as I see it. And what hand can he have that checks the flop but calls the turn? He seems made in some way because there aren't many one spade hands that aren't leading/raising, especially if he's loose. So I think he's going to be difficult to shift off the hand on the river.
