Well my thinking about raising the turn was I didn't want the 4-flush card to fall but I realize now it's not that big of a deal since I have position and could just fold if he leads it on the river. I guess I wanted to get value from my hand (but now that I slow down and think about it value is thin if there is any). So check flop and check turn to hopefully induce a bluff on the river? Since he's either really strong or really weak if he's checking 2 streets after 3-betting.
