If raised on a 3/4 pot bet, it's a pretty easy call. Plenty of hands you're ahead of can make that raise. Combine the likelihood of an overpair/TPTK with the drawout possibilities versus 2pr (which are decent), a set or better (which are not decent) and you can definitely have a look at this turn.

Yes, a 9 on the turn sucks and you're done. I believe any Q has you drawing dead there.
