So far I've been very successful with the Martingale system... up about $10k in the past year and I play about once every other month. I don't count cards, I just play Martingale with perfect (well near-perfect) BS. I know Martingale is known to be a losing system in the long run. At times I have been down more than $5k and they definitely notice that. But of course I always make a comeback. Do Vegas and the California Indian casinos even care about someone like me winning?? Or will they just let me keep winning under the false hope that someday I'll go crazy and lose my entire bankroll?
