The table is ripping you because you're not playing the weak-tight game. No raise without two pair or better! Call down on draws! Don't rock the boat!! [img]/images/graemlins/grin.gif[/img]

While I'd hate to drive out CO, and your free card (which you likely won't get anyway, but I'm sure you knew that) is officially no longer free as of that reraise, another bet for value is not the worst of ideas here. (Folding would be the worst of ideas.)

Edit: Fear of a board pair that hasn't yet come is irrational to the extreme. Worry about it if it happens.

And a flop check-raise, in my experience, is more likely to be hand protection for an overpair, draw, or TPTK. If it were the turn, a set might be the first thing on my mind, but not here.
