(5$) 7 7 Should I push here?

[caretaker1]

At $5, I would fold. UTG limp is dangerous, I suspect that $5 players with mediocre overcard holdings don't know they should be contributing to your fold equity when you push. Do you really want a coinflip here? Also, there's always that outside chance the fellow is sandbagging the big pair as well.

I wouldn't for three reasons.
1) I'm not opening the pot
2) There are 4 people still to act on this round. In $5 you can expect a call here more often than not, and you'll be losing more often than not.
3) SB has me covered three times and can call with less than absolutely premium hands.
