VS Shortstack

[Mercman572]

The popular thing to do at PR seems to buy in with 1/10-1/5 a full buy-in. I'm finding it pretty annoying. How do I go about situations like this?

SB checks, <font color="#CC3333"> Hero?

Can I bet things like this without committing myself? Betting small encourages a push with whatever he has and checking is incorrect if he holds anything that isn't paired. If we're in opposite positions heads up, is the best move to C/R him all in if he's very likely to bet a checked flop?
