I don't mind this, I assume he'd almost always bet the NF (and should b/f) and b/c FH's himself. In a vacuum I think you may get him to fold Jhi and lower flushes and weaker hands, Ahi gonna call, Khi I doubt he ever folds, Qhi is a sort of middle ground although strenght-wise isn't much different, but players often talk themselves into questionable calls because they think in terms of absolute strenght. Unfortunately the runout of the board means that he has less baby flushes, but I think this is still profitable. I like your bet sizing and your line is repping a strong range, while his is weaker, only downside of this play is that many players raise their turned flushes and flopped monsters ott in fear of a scary river, so he may pick up on that.
