5/10 river against TAG

[mjkidd]

My opponent seems to be a reasonable tag, but I haven't really played with him very much.

Folded to villain, who raises on the button. SB folds, mjkidd 3bets 5[img]/images/graemlins/diamond.gif[/img],5[img]/images/graemlins/heart.gif[/img], villain caps.

(8sb) Flop: 3[img]/images/graemlins/heart.gif[/img],T[img]/images/graemlins/spade.gif[/img],7[img]/images/graemlins/heart.gif[/img]
mjkidd checks, villain bets, mjkidd calls.

(5 bb) Turn: K[img]/images/graemlins/heart.gif[/img]
mjkidd checks, villain bets, mjkidd calls

(7 bb) River: 3[img]/images/graemlins/spade.gif[/img]
what's my plan here?
