b/f flop vs an unknown, same with turn. If river blanks I might c/c to indiuce in this spot because it's really realy hard for him to have a hand he can bet for value without raising at any point in the hand and he may often just have a missed fd if he's bad (suggested by his limp).

If he's a total station though I'd b/f river because there'll be a ton of worse kings in his range that will call a bet.

I don't like continuing on the flop If I'm raised often at all in this spot unless I know the villain is really aggro/spewy.
