Check raised on the turn

[Dudd]

I've been making the move from 2/4 to 3/6 over the last few days, and while I played 3/6 a couple of months ago and did decently, I am finding myself very lost playing against agressive opponents. I find myself increasingly lost postflop, constantly getting checkraised it seems. So, I went through my database looking for hands to post, and this seems to be a fairly good example. While playing 2/4, I'd often take this same line, often getting a fold on the turn and usually at worst getting a free showdown should I miss my overcards on the river. That rarely seems to be happening now. Anyways, here's the hand in question. Villian in question appears to be tight and reasonably solid according to me stats, although this line is taken by more than just TAGs. Anyways, here's the hand in question, and what line should I be taking in similar situations?
