I'd check/fold. It may not be right with your gutter & overcards, but if it's not, it's close. Maybe it's weak, but in general, I'm leery of CO open limpers at $2/$4 and up. It's sort of expected that the CO and/or button open raises (or folds) most (if not all) hands. With no read, we have no reason to believe he has us crushed, but I see it quite often & would tend to not fight for this one (unless I see a free turn & improve).

Feel free to show me why this hand in stronger than I think it is.
