1/2 table
Villian is a 20something white male, no particular reads on him. He sat down while I was getting food and I had seen only 2 or 3 rotations since I came back. He seemed pretty decent, not a station. Not sure what his preflop raising range is, haven't really noticed him (wasn't very actively involved, might have forgotten some hands where he was active) in any hands post flop.

Villian has about $300 in front of him, I have over double his stack.

I am SB with KQ. Villian raised to 7 UTG (I think this was his standard raise size). 2 callers in middle position. I flat. I probably should have folded pre, but I didn't want to fold KQ. Kinda fishy, I know. BB calls.

Flop: QT8
Pot: $35

I check, BB checks, Villian bets $30. 2 folds and I flat. My thoughts here are that he has a made hand or maybe drawing with the A. I don't think he would have cbet in a 5 handed pot that is draw heavy. A raise probably folds out everything but made flushes and hands that have me beat. BB folds.

Turn: 7
Pot: $95

I check again and villian bets $75. What could he be raising here that I would have equity against? If he has a made flush, I'm drawing thin. Seeing as how the QT8 are all on the board and I hold the K, there are very few spades hands he raises that doesn't include the As (if any) and I'm basically drawing dead. His bet sizing to me sort of felt like aces and he wanted to protect his hand against flush draws. I'm not so sure if he would have bet so big there if he had the nuts, but I'm not sure enough to factor it in my decision. Something I notice from experience where players overbet or have large bet sizes because they are scared of draws calling and cracking their aces. If he did have Aces, I'm still drawing dead if he has the As which is half the combinations of aces he could have.

How would you guys have played it differently on each street? I'm not sure what the best flop action is for me there. I didn't think a raise was a good move at all, but even calling might not have been great. What would his flop bet range be in that situation? The more I think about it, maybe I could fold even on the flop. What made hands does he bet that I would have equity against? AQ without the spade or QT maybe?

Should have just folded pre, but what are your thoughts on flop?

C/r flop to an amount that sets up a shove.

Preflop, normally that deep I'm calling with KQo. However, against an EP raise that we have no read on at all. I might not. Too often hero will get in this situation, having TPGK and playing guess work because hero has no idea what villain's range is.

Depending on villain just about anything could be right on this flop. Against a nitty villain he will usually have the As or a hand better then yours when he bets, giving you marginal odds and no idea if you want your flush to come in or not. If villain is loose and will c-bet most of the time then your ahead of his range with your pair and your flush draw is often good when your not already ahead.

As played, give up on turn. It's more likely you need your flush to come in to win, but it isn't clear if you can get paid and he bet enough to kill your odds.

Fold PF, bet the flop. Not sure why you think you have to check.

Edit: Just read the responses but I think one reason you're in a tough spot on the turn is you underrepresented your hand. Also against this type of villain he probably isn't messing around and I think you should fold the turn.

I'm fine with this line so long as you folded on the turn.

Preflop, I'm rarely folding KQo from the sb when I'm this deep. It's a trouble hand, but it also dominates a lot of hands that call the $7 raise at 1/2 (KJ, K10, QJ, Q10).

Flop is decent for you, but also dangerous. So sure, proceed with caution. If villain is willing to fire two bullets at this board, he usually has you crushed. There's nothing wrong with calling the flop and evaluating the turn.

I didn't have to check. Honestly, I didn't think it through much outside of I'm out of position, let's see what everyone else does.

Is $7 a normal raise in your games? In mine, it's a pot sweetener raise made with mediocre hands. I've had great success coming over the top of these raises and either taking the dead money down preflop or getting it heads up with a nice overlay. I think a re-raise is preferable to a call unless villain can have QQ+ in his range.

If it's a standard raise, I'm likely folding preflop since the raise came from UTG.

V is leading close to PSB on the flop. If you didn't fold flop, fold now.

Lead the flop. Turn is close, probably fold against an unknown.

Preflop: I am folding this unless I think I can take it down now [or on the flop if I hit] with a healthy raise. That means my opponents need to have a propensity to be 'fit or fold' players.
I have to have built some respect at the table & not been caught bluffing. They have to believe I raise with damn good goods.
If so, I'd raise to $35/37.

I watched this be a successful play some months ago by a semi-pro tourney player on my immediate left. He took off work early & was dressed to the 9's in a suit with cufflinks etc. Talked to players close to him about having just come back from Japan where he played in a tourney. Showed some pics. Very personable guy, who projected the image of a serious student of the game & a TAG style player.
He mentioned early upon his arrival that he was there for a few hrs to play before meeting his girlfriend for dinner. Sure enough, after 3-4hrs play max, he said goodbye and walked off with his 500+ profit.

It seemed like every other orbit he was either on the button, SB, or BB he was doing this after an EP open for $6 & 3/4 callers. Maybe it was every 2/3 orbits. He was called a few times early on, but he showed down stuff like AJs, AQo, KQs or PP. I don't remember which, just that they were premium enough for the frequency of calls preflop to diminish as the session wore on. That's a nice play when you only get called PF 30% of the time or so.

I should mention that he did not win every time. Sometimes he folded on the flop, but I don't remember him paying to see the turn and not winning.
He mentioned that he enjoys playing 1/2 to practice his style of play in the early stages of a tournament.

Maybe he was just running good, but it's been working for me enough to continue. I just have to be cognizant of who my opponents are. I've got to know them. I would much rather take down the pot preflop with KQs/AJs OOP vs. 3 opponents.

However, he was doing this when the tight player, 3 seats to his left folded pre & the opener was a looser player. This invited callers with all kinds of suited cards, etc.

Postflop I agree with QuadJ & GrinningBuddha. I believe Buddha is recommending folding PF when UTG's raise is standard because UTG opens with premium holdings - top 12% or so.
