Turn betsizing, 50nl/100nl

My standard cbet size is 75% psb give or take.

When narrowing Villain's ranges relative to betsizing, and I come up on a situation where Villain likely has a TPMK type hand, flush draws, and some air/float hands on the turn, I tend to size my bet a little over half pot on the theory that Villains will call their fd's and TPMK hands. If I size the bet to 2/3psb, I think I get alot of TPMK hands to stick around but lose alot of the fd's.

I don't change my betsizing for position, but I do change it if I think Villain's a calling station (a little higher if I'm strong, a little lower if I'm not that strong, on the theory that I don't need to balance my betsizing much).

Is this reasonable, or am I missing value?

Jesus you're over-generalizing things here. For a topic that depends a lot on board texture & opponent type, you're really thing to thin things down to a "1 size fits all" solution that just isn't going to work.

Tailor your bet size to get the result you want.

Flush draws don't ever fold btw.

I think one of the biggest leaks of most micro/small stakes regs is they don't think about bet-sizing they let their script handle it for them or have a set size so they're hard to read.

First off against fish bet big when you have it bet smaller when you don't. They're not paying attention to bet sizing as long as it's not super-small or big. Even against regulars it's over-rated. How many regs do you know of and know what range they have when they bet a certain size? Generally it matters what you think they'll call vs. fold though. If you open CO blind calls and flop is A82r why not bet 1/3 pot? If villain has JTo how is he going to exploit you? Floating with J high? Bluff raising more when he reps nothing and has no equity? It's not like he's folding a pair to a 2/3 pot bet. I know the question was about the turn but you're trying to generalize. Use your brain and think about what each bet is supposed to accomplish. If you bet you should know why. Now after you decide you can bet use that why to figure out a good bet size. What hands do you expect to call? What hands do you expect to fold? Does that change based on bet size? Which is optimal given those answers?

Hopefully that made sense but that is just such a huge leak so many people have, not even considering bet sizing and just letting tableninja or something do all the work for them.
