I've been getting good results with a new system I developed. It's a variation of the D'Alembert System. The change I made was simply this, I subtract 2 units after the 2nd win in a winning streak. So, if you won 6 in a row you'd and you started at 10 units you'd bet like this 10-9-7-6-5-4. Subtracting 2 units after the 2nd win. The rest of the time it's just a D'Alembert add 1 unit after a loss and subtract 1 unit after a win, except after the 2nd win in a win streak where you subtract 2 units. Let me know what you think. I don't have a Blackjack simulator so I haven't put it through alot of simulations, but I have been getting good results playing.
