What these guys are saying Harley is that by raising PF you took the initiative in the hand. By check/raising the flop you might scare him off some of the hands you beat, and only get called by better (not always true obviously, but I think it's reasonable to assume that.)

Obviously what Spenda, galop, and myself are saying is that you should have just led out on flop probly around a 3/4 to pot sized bet or somewhere in that area to make him drawing to the flush/straight incorrect.

Next time you'll know.

Hope it worked out!
