Questions:
1) PF: I usually think 1:7 is enough to call pre-flop with this hand. I would expect UTG+2 is call-reraising less than 10% of the time here. Comments?

2) FLOP: I couldn't decide to c/r to protect, or value bet to collect money from highly likely mp draws. Against two random opponents, pokerstove says my equity is 60%. However, on the turn that is going up or down significanlty. Given that I bet, should I three-bet for value or wait until a safe turn to bet again, as I did. Is it close?

3)How's the turn?
