the whole hand was a bit odd for me, as i generally dont limp in much, i dont tend to play offsuit connectors and i dont go for gutshots but i thought i was getting the right pots odds to see the turn and river but also thought i had implied odds to see the turn. to be honest i'm not sure on any part of the hand.
