You have to think about what cards make sense for the opponents to take these lines with, and then figure in a small possibility for some type of bluff or just terrible play.

What kind of hand would you need on this flop to reraise a pot-sized bet? How about to call one? How many of those hands are ahead of what hero has, and how many are behind?

I know for me, if I see a pot-sized raise on this board, I'm probably gonna fold if I don't at least have AQ or AJ, and in either of those cases I would probably reraise.

If I am on a draw, I certainly wouldn't raise a pot-sized bet here. I would fold most draws, unless I had a ridiculous amount of outs, or for some reason thought that my implied odds were very large. If this was limit then sure, raise a draw, but it isn't, so things are different.

Edit - what makes you think the opponent is unreliable? I didn't see a read in the original post. I generally assume people are decent players until I see them do something dumb, but its very possible this is incorrect. If the board were suited, I think putting opponent on a draw when they call a pot-sized bet makes more sense, but not on a board like this. There is a straight draw possibility, but would KT call that preflop raise? Maybe if it was suited?
