I really don't like this cards when I am playing poker, because I lost lot of my money with AJ. However, it is not necessarily in this case.

I also think that you have to bet the turn. For my opinion your bet will have to be about 1/2 pot. If somebody make raise, then go fold.
About the river I agree with Ong ("I'd c/f diamond rivers, c/c Q K, and ideally b/f blanks jacks and aces but I might b/c jacks and aces."), depending on that how much players will be on the river.
