BB is a fishy reg who is tightish preflop but over aggro post flop mostly in terms of cbetting way to much and loving to semi bluff draws.
Once flop is checked through I think he would bet any pair 22+, plus any draw such as 7x and JT/maybe QJ.
He views Hero as to tight but winning reg.
Turn call is because I feel I have enough equity versus his betting range especially as a double paired board could counterfeit some of his small pairs and river bet is to rep AK and hopefully fold out some small pairs. Thoughts?
