* Positive progression betting systems: You increase the bet when you win. Kind of 'let-it-ride'. Require less capital and usually employed to take advantage of winning streaks. (No sweat, easy ride. My favorite.)
* Negative progression betting systems: You increase the bet when you lose. Require more capital and usually employed to force a winning outcome following a losing streak. (Nerve-wracking, very painful when you lose. Avoid these systems if you can.)
* Insurance betting systems: You decrease the amount of your bet when you win, usually following a high initial bet or following short 'let-it-ride' progressive wins. (Play it safe. A good compromise.)
