On the turn, most spades obviously makes the nuts. I also thought any A or 7 or K would be good enough here, given my opponents (very loose and passive). So I have FD + gutshot + 5 more outs (A and 7). Even if we discount that for the times we split with a straight, lose with trip A's to a straight, and are drawing thin against a made flush (which is not very often), I think it's a pretty decent value bet. Let's not forget that once in a blue moon we will show down sevens unimproved and win the pot vs. 2 busted draws.
When it comes to respecting my opponents, I have found that in general at nano-limits, it's better not to try to figure out what my opponents are thinking or doing. If I just play my hand and the board, I tend to profit more than when I try to put non-thinking opponents on a hand and end up seeing Monsters Under The Bed.
