Am I gun shy on the river

[dcarlc]

Been running a little poor last couple of days and was wondering if I missed a bet on river or if this is ok.
BB is loose and not very agg(52/10/1).

Party 5/10, 5 handed

fold, fold, I raise K [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/heart.gif[/img], SB folds, BB calls.

Flop:7 [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/club.gif[/img]9 [img]/images/graemlins/spade.gif[/img]

Check, Bet, Call

Turn: 5 [img]/images/graemlins/spade.gif[/img]

Bet, Raise, call

Check, I?

My thought when he led the turn, some draw with a pair possible? Was just wondering if this a standard value bet?
When your going bad you start to think, not check raised again or they just fold.

Thanks
