I think its best not to raise from the SB, playing... any hand out of position = hard, let alone AJ. Metagame speaking I think it sucks when you consistently raise with good hands, and have to fold to a raise/flop bet if you miss, especially out of position.

You should bet the flop, and you should probably bet the turn, but the river is a definite fold. It's pretty hard not to lose some chips when you're playing TPTK vs a sandbagging set.

My concern is giving free cards/having to call down pot sized bets if you decide to check/call the turn and river...
