It turns out that you can’t do better than a chance in ten of multiplying your bankroll by a factor of ten, even with the very best strategy. That’s a general rule for fair (or almost fair) games: the probability of achieving your objective before going broke is exactly the inverse of the amount by which you want to increase your fortune.
