The four-color deck makes me nauseous.

More information would be good, but I think I can piece most of this together. The pot is too small. You should probably have raised on third and definitely have bet double on fourth. Give them a chance to fold. Anyway, I bet fifth. If he's a good player, he has you beaten, but there aren't a lot of good players playing $.50/1.00. If he raises, be inclined to call it down.

I have posted this on many occasions, but apparently not enough. I am very much in the habit of calling down open four-flushes with two pair. This is probably a loose player--it's certainly a loose game--there are lots of things he could have. Now if he does make a fourth heart on sixth street, I'd go into chicken-call mode unless I filled. If not, I probably bet sixth. Whether I bet the river unimproved depends on who all's left and what they're showing, but I would be somewhat inclined to bet anyway.
