Poker

Most poker books and training videos on tournaments and Sit 'n Go's are by professional poker players who play at the highest stakes. Whereas you can learn a lot from studying them, they won't always be as useful to you when you're mainly playing at the low stakes.

Now, go start crushing the game.
