Foxwoods $600 NLHE Tourney hand

[Toro]

Hand from todays tourney. Blinds are 50/100 no ante. I have about 5000 and villian 4000 at start of hand.

I have 8 [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/club.gif[/img] in mid position and make it 300 to go. Cutoff calls and everyone else folds.

Flop: K [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/spade.gif[/img]

I bet 500 and he calls quickly.

Turn: 9 [img]/images/graemlins/heart.gif[/img]

I bet 700 and he again quickly calls.

River 5 [img]/images/graemlins/heart.gif[/img]

I check and he fires out 1400.

Do you call or fold and any other comments on how I played the hand?
