I"m wondering how much different my play at 100BB vs 200BB would be in this position, if any, since I lack experience playing 200bb+. I don't think the hand is too interesting as I think this would be an easy fold at 100bb. Would the same apply at 200 or even 300bb deep?

V: Mid 30's, Caucasian male. Appears to be a reg. Has a baseball hat and hoodie jacket, but doesn't seem like the young internet type player. Passive pf in EP. I've seen him limp in EP w/ Aqo, limped/called UTG2 w/ 44, limps w/ Axs, Kxs, broads Post-flop, he is passive. I've seen him check call three streets with both TPTK and TP 2nd Kicker.

Hero: Mid 20's. Been very aggressive pre-flop, 3b very liberally, and have been c-betting a majority of my hands. Most hands do not go to showdown but when they do, I have won the pot.

SB: Typical weak tight. Does not play too much of a role in hand.

Eff: $400 9 handed
Folds to V in MP. V limps. I iso to 13 w/ KhTs. Sb calls. V calls.
-PF size varies from 7 to 15. Maybe I could have went a little larger pre?

($35 due to rake)
Flop
Ts8h6h. Checks to me. I bet $25 dollars for value. SB folds. V check raises to 65. Hero? I have Kh

I want weaker T's to call, 8's to call, flush draws to call (AhQh,AhJh,AhTh+ other Ax's). I know I will be beat by sets, AT. I think 6's fold. I discount J9/97 and two pairs. I think any 6's fold.

When V check raises, I narrow his range down to AT, T9s, sets, discount two pairs; heavily discounted 2overs+flush draw/ flush draw+gutters (A7, A9)/ J9/97.

As I said earlier, at 100bb, easy fold w/ reads. At 200bb, still an easy fold? With suited AT/KT, this would be a call @ 200bb?

limp or fold pre. i usually fold pre. KTo is trash.

you call villain passive who calls down with TPTK for three streets - and now he raises you? easy fold.

This.

Raise more pre for iso.

Limp or folding pre is standard for 1/2. I completely agree KTo is trash. 100%. Maybe I have a huge leak. I will generally come in for a raise, as well as Iso a limper, based on my position, as well as my image. If I can get it heads up between me and the average passive 1/2 player where we are at least 100bb deep, I have initiative and position, I am 100% playing this and overcoming their card advantage.

Edit: Also, I believe when a player limps Aqo UTG and check/ calls small bets ($5/$5/$10) in a multi-way pot on a dry board passive.
