Flop 2-pair, Turn a Boat

[J Chap]

[cen-[censored]-sored] pokerroom cant find hand histories.

NL 100.

i limp AJ on the button.

flop is JKA rainbow.

checks around to me, I bet pot ($5). one caller.

turn is another J. so i have a boat.

he checks. I wait a bit and then bet $12.

Is that okay? I'm trying to let him represent the trips or whatever...it definitely works at NL25 and NL50.

Or do people check this behind and hope he bets the river?

Thanks; trying to maximize value.
