Limping gives you a decent chance of three opponents if the SB completes and there is no reason why CO or the button won't limp in also. Your opponent seems to be tight, so raising is less attractive than it might be agaist someone who will limp in with any ace regardless of kicker. Against a tight opponent the chances are that you are either behind already to something like 99, 1010 or more likely will be facing two overcards, in which case you are little better than even money to win the hand. There is some discussion of this kind of hand on page 66 of SSHE. I agree that it is close in this particular hand though, and I doubt whether it will make a significant difference in the long run whether you raise or limp.
