Passive played AQ when I flopped trips.

It looks like your opponent has a big pair or AK. If he has a big pair, raising the turn is better, since he might not bet the river since he is weak or choose to check and hope to induce a bluff from a possible spade draw. There is also the remote chance that he three-bets the turn with his big pair. Finally, you will often be raising the turn light for a free showdown or even the occasional semibluff, so you should do it with your monsters as well.

If he has AK, then waiting to the river to raise is the better play, unless he has specifically AsKs, because AK would probably fold to your turn raise, but will likely check-call on the end (hoping for the spade draw) or bluff bet the river.

Overall, I think a turn raise is the better play.
