g'day Burt!
I'm also a U.S. Citizen, although I'm currently living out of the country. I feel your pain. I also play SSS.
I don't know you, or how well you're playing, how closely you follow the strats, where your mistakes are, etc, so I can't offer much in the way of guidance there. I would say if you played well enough to get your roll from 10 to 175.. and you did it while following a good Bankroll Management Plan, then you probably don't have too much to worry about.
Did you move up limits recently? If so and you've done badly, did you move back down? Do you use a tool to analyze, and replay your hands when you're done? (Like pokertracker, or holdem manager)?
What I like to do.. I play my session, and sometime later (often after dinner) I'll come back and sit down with my partner, and we'll look at the hands I played during the day. It doesn't take as long as it might sound. Since you're playing SSS you're only playing maybe 6% of all the hands you're dealt. So go back, look at every hand where you lost money, and where you won money. Replay them, step by step through each street, and see if you always made the right decisions on each street.
If you did... then it's just bad beats, variance.. nothing to worry about.
If you didn't.. take notes on what your mistake was, each time. You may find you're making the same mistakes over and over. Are you one of those who can't lay down KK when an ace hits the flop an opponent betting into you? Maybe you hit air with AK on the flop, and you're overvaluing your trash hand? Maybe you're trying to steal too much and you're not getting away with it... or.. whatever.. make notes, and learn from them
sorry, I had something else I had wanted to mention and I was interrupted while typing this, and now I can't remember. If I do, I'll come back later and edit the message.
But the most important thing, I think, is to be HONEST with yourself. You're hurting no one else, but yourself, if you're playing badly, but piling the fault onto "bad beats".
By reviewing my sessions with my partner, it helps keep me "honest". If I make a stupid mistake, I have witnesses. ♦ So, that helps me as well to make the right decisions, knowing that every hand will be reviewed by a committee of people who have no fear telling me how bad I sucked, if indeed I do. ♦ It's my own personal Tribal Council.
You don't have to have your own tribunal or anything, but it's important to be honest with yourself. Post hands in the forums for review, if you have any questions on them. don't give up.. just be honest with yourself.
By the way I play on PokerStars. I play SSS. I still manage to make a profit (although slower than I would on a rakeback site), So it is possible.
