1st post on this site, although I have been picking up some great info & tips. Thanks to all!

Partypoker 3/6 full table, no reads on anyone as it is early.

My questions are did I play it correctly preflop(no raise into 5 limpers), and should I have raised the river? My thought at the end is that he could have limped his AK in mid position or possibly slow played 89s after flopping the straight. He wound up having JQo, surprising me.
