Is this a place to slowplay ? Set of Kings NL25

[TheBad]

Villain was like 25/8 after 20 hands, so no real reads. Didn´t notice him before.

Final Pot: $40.85

PF: Maybe a little bit big, but i really didn´t want some random Ace to limp/call.

Flop: Villain instachecks. I decide that my hand is strong enough to give him a free card. After my big preflop raise, he really can´t call a bet here without a set or AQ, right ?

Turn: That deuce probably didn´t help him, but he bets. I minraise not to loose a customer. Why chase him away ? I try to look as weak as possible.

River: Tricky. He obv has no King. If he has a set/boat, he will reraise anyway. So i try to get some value out of AQ or 2pair, right ?
