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

<font color="blue">I'm totally lost in situations like these. Villain has just a wee more than a PSB left. I can't bet without committing myself to the pot. I figure the only two options i have are:
1.: Shove
2.: Give up

And I don't like either.

I need a general advice here for situations where, being the PFA, I face small to medium Stacks, miss the board completely and a standard C-bet would commit myself to the pot. How am I gonna play these Situations in general??</font>

Thanks for comments and/or discussions.
