NL 1/2 Two tough hands vs. maniac

[Burdzthewurd]

NL 1/2 3-handed

Villain's SN is IAmDanHarrington but is anything but a nit. First hand he sat, UTG raised to 6, I made it 21 with Kings and he made it 52 in the BB, with UTG folds and I smoothcalled. I check/called a donkbet on a KQ5 rainbow flop, then check/raised his donk turnbet to 40, he called, I shoved blank river and he tabled 55 naturally. Since then he has raised almost no hands on the button, just limp/calling when I raise in the BB, and hasn't reraised me pf since. He'd occasionally would overbet pot or just open-shove some flops/turns when I had nothing, and always c-bet when raising pf. Since that hand I chipped up to $300, he has $650.

Hand 1:

Villain limps, SB folds, Hero raises to $9 with Q[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/spade.gif[/img], Villain raises to $16, Hero calls.

Flop K[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/heart.gif[/img]

Hero checks, Villain checks.

Turn 7[img]/images/graemlins/diamond.gif[/img]

Hero checks, Villain bets $16, Hero calls.

River 8[img]/images/graemlins/diamond.gif[/img]

Hero checks, Villain bets $64, Hero?

Probably needed to 4-bet preflop to $65 or something right? I was puzzled by him checking back the flop. Do I have to call river if I'm calling turn?

Hand 2:

Same stacks as before

Villain limps, SB folds, Hero raises to $9 with K[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/diamond.gif[/img], Villain calls.

Flop 7[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/club.gif[/img] 2[img]/images/graemlins/spade.gif[/img]

Hero bets $14, Villain calls.

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

Hero bets $38, Villain calls.

River K[img]/images/graemlins/club.gif[/img]

Hero checks, Villain bets $116, Hero?

I haven't seen him fire pot on the river unless he bet pot on the flop/turn as well. Fist-pump?
