I'm not very experienced, but I've noticed that the best strategy is to go big in one or two rolls or leave it.
The longer you try to play, the more likely it is for the possibilities to turn against you!
It makes sense you know, since the chances are usually around 51% you'll lose.
That's true with any game really, you can almost certainly beat the house in the short-run, but in the end, you will probably lose out.
The reason most people lose money is simply because they don't understand this simple fact. If you're in a profit, take your money and call it quits.
Otherwise, continuing to risk money may give you the chance of a bigger payout, but more often than not you'll lose.
