I'm a fish every time I flop 99 w/gutshot HU

That is an interesting post and perhaps calling down is better here (definitely something to consider). In my experience though since I have started making this play at 3/6 (not really all that often, maybe once or twice a session), 50% of the time the opponent does fold. Perhaps I've always had the best hand, but I doubt it (there have been some looong pauses). Also keep in mind at 10/20 most players understand the free showdown play and turn semi-bluff raises where at 3/6 and below this is not necessarily the case so I think your folding equity is higher.
