Easy river fold?

[Glurfle]

Party 2/4. No particular read on the player in question - he'd been there for a little bit, I hadn't noticed anything out of line.

3 limpers to me and I raise A[img]/images/graemlins/heart.gif[/img]K[img]/images/graemlins/club.gif[/img] somewhere in LP. BB and limpers call. 5 to the flop for 10 SB.

Flop: K[img]/images/graemlins/spade.gif[/img] J[img]/images/graemlins/club.gif[/img] 4[img]/images/graemlins/diamond.gif[/img]
Checked to me, I bet, everyone calls. 5 to the turn, 7.5 BB.

Turn: 2[img]/images/graemlins/spade.gif[/img]
Checked to me, I bet, BB and EP call. 3 to the river, 10.5 BB.

River: 9[img]/images/graemlins/spade.gif[/img]
Checked to me, I bet, BB calls, EP check-raises, I fold.

Good fold. I haven't played online $2/4 in a while, but I don't think there is much checkraising on the river with hands that lose to one pair.
