What can I do here?

Should I fold this junk hand preflop? I figured I was getting pretty good odds to see a flop for only t25.

Not sure how many replies you'll get, as most of the traffic here is in NL SNGs, but let's see.

I think K2s is probably enough hand to complete the SB with behind 3 limpers when the blinds are this small, so that seems okay to me. (Disclaimer: most of my limit experience is in games other than hold'em, so I'm winging it here. But this can't be a huge error either way, I don't think.)

The only alternative plan of action I see is to three-bet the turn to try and drop some of the others, because I don't think you want wheel cards or Ax to be hanging around to see the river. Other than that, I think this played out pretty much according to form. Check-calling the river seems good to me.
