I think I've finally found my game: 6 max NL turbo tourneys
But I'm stuck. I make a killing on the $6.50s, but every time I get my bankroll up high enough to try $13 games, I can't get anywhere. After a session with them either I've broken even or gone down a buy-in or two. Whereas with the $6.50s, in a month of sessions over 90% of them are positive.
It's very frustrating! What can I do to get unstuck?
Also, I've never read any books before, and I'm curious what would be most helpful for my game.
