Even if it's impossible to calculate, what is approximately the best sizing against a range with lots of straight draws and flush draws on the turn (who have approximately 20% equity) ? Between 1/3 and 1/2 pot ?
I'd just go one step further now and say this:
"In general, the weaker our opponent's range is relative to ours, the more frequently and bigger we should bet. The stronger our opponents range is to ours, the more frequently we should check and when we do bet we should bet smaller."
Equity distribution is more complicated than that, but that's it at a glance. Draws are usually pretty weak (especially on the turn) so the weaker villains range is, the more and the bigger you want to bet.
Also, it's less important to make a flush draw unable to profitably call so much as you just need to reduce it's expected value. So say I'm playing against you and you have a flush draw on the turn and the pot is $100. If I check, let's assume you'll check back and the EV of your flush draw will be $35 (I'm of course making numbers up). But if I bet $50, maybe the EV of calling will be +$5 and you'll always. So while I didn't bet big enough to make you indifferent to calling or folding, I did greatly reduce your EV by betting instead of checking. That's usually good enough, and frequently what I have to do as I can't justify a bigger bet or I'll lose to much to your strong hands.
