Money management seems to be a required subject in any discussion of gambling.
All too often it is claimed that money management alone will make you a winner, even in a game with an unalterable house advantage. If you want to be a real winner, however, it is necessary to develop the skills to beat one or more positive expectation games, and to play only those games where you can achieve a true mathematical advantage. It has been proven by hundreds of mathematicians that no form of money management or betting system can give you the expectation of being a winner in the long run at a negative expectation game. Unfortunately, this hasn't stopped hapless millions of players from losing their bankroll by following such a system. Just send me 25 percent of your winnings the first time you use my system.
