in the SB w/ 55 (come and play)

[soweak.]

I think pre-flop your fine with a call. On the flop, your position makes it a raise/fold situation, with calling (in my opinion) being your worst option.

It really depends on your table image, and how likely the field will bite and fold to your C/R. I would probably muck seeing as this flop is most likely to have hit the field as opposed to a flop like 993r.
