i had no reads, so min raising pre flop was pretty bad (not used to party's software and had to act quick)...but what about post flop? would you take a different line on this dry of a board?

my 1/2 pot bets were supposed to get called by a worse pair or raised on the turn by something better. The flat calls meant probably a boat or KJ/AJ to me or else a stubborn pair thinking i have AQ/AK, so I blocked-bet the river.
