Personally so far I fold my SC's pre vs a raise. I only play this hand on a steal, possibly vs one limper. That is because 1) I am not good enough postflop to play my SC's profitably against a PF raiser 2) I think people don't fold enough at these stakes to make SC's easily profitable. I think it is commonly agreed that SC's are generally profitable only if you (successfully) bluff with them a fair bit.

As played, I agree with checking the turn against two opps.
