Agreed. If you can't slowplay a freakin' boat, what can you slowplay? You WANT him to hit his flush, it's just too bad it happened to be a Str8 flush. Once the Str8 flush is out there, maybe just call his river raise as Fnord suggested. The idea of slowplaying the full house, however, was just fine. It's one of the safer hands TO slowplay. I personally don't slowplay much else but these against any kind of flush/St8 draw possiblity.
