Dont get me wrong im not a wiz when it came to this game but it was clear you were beat on turn idk bout flop but definitly turn and river was just a cooler
I would have folded earlier based on my experience with pocketpairs. Sometimes a seeming blessing is a most unfortunate event. Would have went all in after that river though for sure. Bad beat for sure.
Were flat calling two streets its pretty obvious what we have a straight draw one float is fine but we are clearly massively behind after the turn bet time to let go of 7's after the flop float..
Its a good board to rep a straight if you have a read on your opponent but given the board texture the only hands he could be betting is trips full house or a straight on the turn,
He would of 3-bet an overpair in most cases pre flop\
