Done it. Always been successful at it. But, it's impossible to do without being detected and during a two year period I was effectively banned from one of the major chains in Vegas. The ban was lifted, but by that time I wasn't as interested in blackjack as I was winning even more at Baccarat, a game from which the casino never bans anyone.

There is a lot of nonsense written by low end shysters who purport to be successful card counters, about deliberately misplaying or underplaying your game. I never played like that. It's hard enough to win such that if I ever saw an advantage I always went all the way - all the way to table limit - with it, and took all I could. I certainly never "took it easy" on the casinos when I had an advantage going.

If you ease off when you should be pouring it on, you'll probably find that whatever advantage you have is eaten up by the times when the advantage is not here, or worse - when the advantage is there but variance luck whatever you want to call it works against you.

But in the end, blackjack is not a game where you may win indefinitely. Eventually the casino will turn off the spigot if you take enough from them at what they view as a game of skill.
