Stars $50 - 55 OOP, but flop checked

[JSampras1]

I should raise 55 utg? If i was in later position i definately raise, but I want to make sure if someone has a big pair that i don't get raised out of the pot, because i am very very likely to stack if i hit.

I wasn't stone bluffing here. I had a good feeling that everyone whiffed. If the raiser had anything he bets 100% of the time. The other guys are donks, but they had chances to bet into obvious weakness, and they checked.

If you change the turn card to a deuce, this would be a horrible bet? What if i bet half the pot? You're telling me that there isn't a 25% chance these guys fold here?
