Correct to fold here?

[Roy6]

First orbit, no reads.

Poster checks, I raise on the button with AQo.

SB and poster call

Flop is QK8, 2 [img]/images/graemlins/diamond.gif[/img], I have no diamond

check-check, I bet, only SB calls

Turn is 9 [img]/images/graemlins/diamond.gif[/img]

SB checks, I bet, SB raises, I fold

Is this standard? I have 2nd pair, and I'm drawing dead to a staright or a flush. The pot is not so big. Even if I hit, I cannot C/R.

The question is how often do they play something like Q [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/diamond.gif[/img] this way?
(I've been shown very cheesy things lately, like opponent C/R-ed then capped the turn with A2 no pair. I held AA).
