Stacks: BB $3800, me (UTG+1) $1800, HJ $2200.

My image is young TAG grinder, quite tight image, played very few hands compared to the table, the table is aware of that, the table saw
me raise a straddle with ATs in MP and c-bet it on a whiffed flop into 2 players so they know that although I'm tight, I do have some aggro
in me.

BB is a rather competent player, knows relative value of hands, knows to just call when worse won't call a raise, pot control, generally
tight but is capable of being aggro such as 3-barrelling air HU. Overall, like his play quite a bit. HJ is a recreational fish, 55ish businessman
looking dude. He loves to play hands and plays way way too many, so he's very loose preflop. He's capable of bluffing postflop and tried to blow me off KK
(unsuccessfully) with a turn and a river bet on AxxxA after I checked the flop. He's much tighter postflop then preflop although he is bit of a station postflop
and will easily peel two streets with middle pair or a gutshot.

I open to $50 in UTG+1 with AhAd. Why $50? Because HJ will call $50 just as well as $30 and I want to play with him and don't care for anyone
else to call. He calls, BB calls. BB is pretty wide here because he'll flat a ton of SCs, suited Aces, etc, especially now that the fish is in the pot.

Flop: Tc6s6c Pot ~ $160 BB checks, I bet $100, HJ calls, BB calls.
Turn: Ks Pot ~ $460 BB checks, I bet $300, HJ calls, BB calls.
River: 3h Pot ~ $1360

Action is on YOU. I have several specific questions:

1) Do you see any mistakes on earlier streets?
2) What's your plan for the river? Please be specific with bet sizing.
3) Are you ever folding river and if so what would it take for you to fold?
