Call or reraise?

I find situations like these some of the most difficult to play in poker; when you have a fairly good, but not excellent hand and someone is playing back at you. In general, do you guys think you should call or reraise in these situations, and why?

I play tourneys mostly but when I get in this spot I definitely re-raise him to see if he likes his hand enough to re-re-raise. In a cash game though I probably wouldn't because I'm scared money in ring.

his turn check makes me suspicous of the FD.. he was blatently looking for a free card. These situations are tricky, at my min stakes i normally continue the aggression at the turn even though they c/r me at the flop. if they re raise the turn its time to slow down or even get out depending - but at my stakes they quite often have TPGK.
