TPTK on paired board vs Drooler - River decision

[Emmet]

River line here had me kind of stumped. Its probably very basic, but I've had a dreadful session and I'm not sure if I played this right.

Villain is playing 53/0 over 80 hands, fold to cbet is 44 and aggression is 1.4.

What is the right river line?
B/C?
B/F?
Check?
C/C?

What bet amount either

No-Limit Hold'em, $0.20 BB (4 handed) - Hold'em Manager Converter Tool from FlopTurnRiver.com

BB ($20)

Preflop: Hero is UTG with K, A
Hero bets $0.70, Button calls $0.70, 2 folds

Id bet about 6.90.
Wouldnt expect to get shoved on much.

Hes calling down any Ace.

[Bubbleking]

depending on how bad he is I might shove

If you bet less than a shove then I'd fold if he raises. He's not raising worse here ever.

That said, shovings best as he'll call a lot of the time with worse and not shoving is losing value.

[Starvin Marvin]

Shoving what will be a 2x pot size bet looks strong even to the biggest droolers.

I think it will let him get away from some hands that would call a 3/4 to pot sized pot.

[RoadSweeper]

Shove seems a bit much, but he does seem a bit special. I prob bet $10 or so

[handofgod]

bet around 9

[Moneymaker]

I like a shove. Or i'd bet $7 or something.

[Emmet]

If you bet less than a shove then I'd fold if he raises. He's not raising worse here ever.

Yeah this. I think I went with the majority here when thinking that he would call a big river bet.

Led out for 8.20 and he shoved.

I tanked, but figured that I'm good here sometimes, his A7 had me crushed. Cooler I guess.
