At this particular table, you obviously need to raise more...50 cents isn't clearing the field.

Yeah, the CB on the flop in this particular situation seems to be a small leak...into four other players you are going to hit a person who has an ace probably 85%+ of the time who won't let go of it.

Also, if CO is a calling station, make him pay for his last card on that turn when you have second nuts! Probably a bet of $4-5 I like more. Get him committed on the river.

1) Agree with briachek..dont bet that flop
2) Agree with Dan, raise more preflop since obviously these guys like to call

Once you get to the turn...pound it. People who call raises with things like A8 will call you down when an A flops. Bet 3/4 pot on the turn.
