Is my line in this hand crooked?

No reads.

Flop: (7.33 SB) 2[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], 2[img]/images/graemlins/heart.gif[/img] <font color="blue">(2 players)</font>

River: (7.66 BB) A[img]/images/graemlins/club.gif[/img] <font color="blue">(2 players)</font>
Hero checks, MP1 checks.

I figured I would be 3-bet by an overpair on the flop more times than most, if that was the holding. I also believed that if called, a hand like AK or AQ would either fold to the turn bet or peak at the river (player dependent). Unfortunately, no reads were available on this player.

Final Pot: 7.66 BB
