I'm playing 1/2 with about $350 in the SB, villain has me covered. Four or five players limp and I complete with K5cc. BB raises to $10 and everybody calls so it's about $70 to the flop which is AAJ with two clubs. I check, BB bets out twenty and I call. BB is an old guy with a bit of gamble in him and definitely a calling station. I feel like he won't fold to a raise here so I just call, everyone else folds and It's about $110. The turn is the 7c and I lead out for $50, he shoves so I have about $260 to call to win just shy of $500. I feel like I pick up a bit of a read that he's confident but who knows. Thoughts?
