3/6 facing flop donk on dry board

[Surf]

3/6 6h, game is a bit passive preflop, but aggressive postflop, players full potting TP on bad boards, etc...generally poor hand reading / relative hand strength observation. No reads on villain here, he's only been at the table an orbit or so.

$600 eff stacks.

Fishy limper in MP, i raise to $27 w/ K[img]/images/graemlins/diamond.gif[/img] K[img]/images/graemlins/club.gif[/img], villain calls in BB, limper folds.

Flop: 3[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/spade.gif[/img] ($63)

BB donks $63, I call(?)

Turn: A[img]/images/graemlins/heart.gif[/img] ($189)

BB bets $75, I call(?)


What's my plan for the river? if he bets $85 or so? if he pushes?(i can't call obv, but what do we think his hand range is and what's our minimum calling hand?)
