I would play the hand a little different.

Flop check is good.

I like leading the turn but I would only bet 1/2 the pot. That should be enough to take it down if neither opponent has anything and if only one opponent with a single spade calls he's only getting 3:1 to make his flush draw. If either opponent raises I would fold. If both opponents call I'm not putting in any more chips on the river regardless of what comes.

I would then check/call this river provided the river bet is less than pot size.

As played you have a difficult decision on the river because your pot odds are so good. Against most opponents I would fold.
