MP checks,

villain is tag. checked flop to control pot size. turn call obv. river: im thinking that this is a good spot for villain to c/r with hands like aq or kk and i'm worried about that. i'm not positive about that though because i havent shown strength. if i bet, the only thing that calls that im ahead of is ak.

I would bet flop and I v-bet river.

The way you played it I think he calls with QQ here often.

BET FLOP!!!!!

value bet river ~40$ when he checks

the whole point of taking this line is to get value out of TPWK or 2nd pair. Definitely value bet this river. this is pretty elementary imo. Bet like 2/3rds of the pot.

bet flop for sure, even this deep.

i would Vbet the river 100%

Here is the narration that went thru my mind as I read this post:

Preflop: "Oh, yeah! This is gonna be sexxy!"
Flop: "Oh, NOOOOOO! 1000 puppies just died"
Turn:" "Oh, I get it, he's checking to induce value! Ok, 500 puppies revived..."
River: "LOL? Wait, he wasn't checking to induce???"
