Bubble Trainer
"The Bubble Trainer is a tool designed to help you develop perfect late game skills in a poker tournament. It’s all about math, but there’s no way you could do all that math in your head. There’s no reason to either, if you can just make it instinct. Practice makes perfect.
Not only will you learn what the correct play is, but you’ll learn why. You will learn exactly how much money you win with every push. You’ll learn when to pass up close decisions in a real game."
