I built a quick simulator in Cocoa that dealt cards from a shuffled six-deck shoe. As each card was flipped over, slowly at first, the background of the application flashed either red, for -1, or green for +1. At random intervals, the application would stop and ask me whether I should bet low or high. If I was wrong, it flashed and beeped like a expensive car in a hail storm. If I was right, it kept going. Over time it randomized its speed, so I’d never fall into an easy rhythm.
Now that’s a way to train yourself on something. Big Contrarian → Putting it all on black.
