A weird AJ hand

[Spicymoose]

SB here is 30/24/28 after 300 hands, CO is 24/20/2.2 after 150.

Is preflop standard, or bad because the PRF was prety TAGgy? What hands do you think SB could cap the flop and then check the turn with? Should I bet here? I was afraid of a check raise. Is the river bet ok? I assume you are paying off a check raise if it happens, but will almost always lose.
