I read OP, didn't read the date, and typed in almost exactly what I posted last year....so I guess my thoughts on this have not changed much.

Let's say our opponent is going to play 100% straightfoward and we'll use set-mining b/c it's the easiest example of a "draw" . Like surviva said, if our opponent is going to play fit/fold then we either need to re-raise to an amount that makes it mathematically incorrect to do so or to play a range that

1. Has more equity against sets when the money goes in postflop
2. Gives us the ability to play aggressively postflop
3. Allows us to fold easily postflop when facing resistance

The problem becomes with playing against people who don't play fit/fold. Against those we'd adjust by either stacking off lighter or tightening/strengthening this range to avoid marginal situations.

(I may not be thinking 100% clearly so if anything doesn't make sense call me out and I'll revisit it when I'm not popping pain meds).
