I'm going to go on a bit of a tangent here, but I feel the need to address this sentence here:

Do you ever think that anyone is folding a flush draw on the turn for 1/2 pot? Even a nit or thinking reg won't fold for that price, and here's why:
When you bet 1/2 pot on the turn, you're giving the villain 3:1 pot odds
on a call. That is: if there's x dollars in the pot, then they would be calling x/2 more dollars to win a total pot of 2x dollars. Now, flush draws on the turn require 4:1 pot odds to make them break-even calls, so it appears that they're not getting the odds to call, however, you need to factor in implied odds.
The reason for calling a 1/2 pot bet on the turn is that they believe they can extract more value from you on the river if their draw hits. And I don't think that this is an unreasonable assumption to make, most of the time. Let's say you have TPTK and that third spade hits on the river. You're probably not going to want to stack off completely, however, you're probably willing to call about another 1/2 pot bet, especially if there were multiple draws out there and only one of them hit. So if there's now 2x dollars in the pot and they bet x dollars, you'll call and they'll win a 4x dollar pot. So all in all, by putting x/2 dollars at risk on the turn, they were able to get back 3x dollars, which gave them 5:1 implied odds, despite only getting 3:1 direct pot odds.
Long story short, you have to think about the implied odds you're giving them, not just the pot odds. Even a nit isn't folding a flush draw on the turn to a 1/2 pot bet, provided you have some stack depth behind. I'll typically bet around 80-90% of the pot on the turn if it's a 2-tone board and I have top pair. Many people (I'd even go so far as to say that the majority of micro stakes players) will overestimate their implied odds and call this.
