My first reply here will be a story of how you should proceed with caution when actually using this system... I used this system at an online poker site before online gambling became illegal in almost all of the United States. I invested only 50 dollars of my money initially and my first investment was doubled to one hundred dollars. I took a timid approach at first and started my first 5 dollar bet after 4 blacks in a row and was betting red. Not much time had passed and I broke 500 dollars. I then started betting my initial 5 dollars after a win, after two losing blacks like you mention in your example. My original 100 dollar bank roll eventually turned in to over 1800...... then I was astonished when I lost over 9 bets in a row. Proceed with caution. I will reply again in a while about some overlooked math. And go into some theory behind why this doesn't work. Unless as you say you have a crap ton of money.
