[Sciolist]

#1: Fold - we need to win too much on average on the river if we hit, and we only have seven clean outs. Too much of his range folds to our ~$45 bet on the river if we do hit a clean out, and if we hit a board pairing club, we could end up losing instead.

#2: Check Fold - We don't know if our A or Q is good if we hit, and we certainly don't have odds to draw to the K. The 3 didn't change anything so I don't like a second barrel here.

#3: Fold - We are assuming BB is an OK player? If so, BB only called flop because he wanted the bad player along. He didn't get it and now he wants to stop us getting a free card. This is because he has a set or small overpair. If we call the turn and hit, even if we stack him every time we lose money with this play.
