I agree with most of the things others here pointed out that you should consider like stack sizes, opponent's tendencies, etc. But, I don't agree with the idea of raising. First, folks who say raise probably haven't thought through their strategy. Why raise in this situation? Are you trying to induce a fold? If so you will have to put in a large raise to try and push the other player off his hand. Even if he just calls you have so much in the pot already you are probably heading for an all in. Not a good plan with AJ off. And, what if the other player responds to your raise with a shove? With AJ you are going to fold. So, either way, raising is a bad play.
