Pre Flop : I think raising from the BB is tough here because it's always going to leave us OOP throughout the entire hand if we get called.
Looking at the level you're playing on I think it's safe to say we're ahead here, villain most likely limp calling a raise PF with so many hands that we beat, low to mid PP being a massive part of their calling range, AQ villain is raising, AK villain is DEFIANTELY raising, so we can discount them.
Flop : You're bet on the flop is fine,
Turn : I'd be REALLY stuck in a hard spot here on the turn, I don't like the turn card at all! It puts us in a spot where if villain is limp calling a raise PF with a hand like AT then we're crushed, also villains at this limit WILL call over priced gutshot draws which they would have alternatively caught aswell Back to the turn, I would most likely fire a bet out here though. Far too many times have I seen villains calling down with raggedy aces. I'm not too sure who will agree with me on this but I think you're going to be getting your chips in the middle with the best hand.
