Thin Value Bet?

[soah]

I started to check. Then I realized I will almost never get raised here and from the way he's played the hand, it looks likely mine is good. And there are some possible worse hands that can call. I wasn't sure how much to bet and after taking some time I ended up betting $90 (about half the size of the pot). He folded.

Still not sure about it. My line looks like a slowplay (flush) and that will make it hard to get paid off by kings on the river. My bet may be small relative to the pot, but it's still a lot to risk on a crying call (and it looks like a value bet). I may have been better off betting bigger and hoping it looks like a bluff (but I'd like to have a read that tells me my opponent will fall for it before trying it) or just betting so small that my opponent feels compelled to call with anything.
