First, if you are good, then you WILL get caught sooner or later. This is why I encourage new counters to do their homework on issues of surveillance and playing styles to protect their longevity.
THE WORST THING YOU CAN DO IS USE A PLAYERS CARD TO GET THE FREE SHIT. The comps will never be more than the cost of being banned at a casino. Big negative play. Longevity is king.
Being backed off, counter measures and trespassed are the bane of card counters. I have been dealt with by one or more of these in 10 casinos and am the un-proud member of the Oregon Surveillance Network website of card counters, cheats and miscreants used by most casinos to track low life's like me. LOL I am being sarcastic but accurate.
Casinos obsession with card counters is ignorant and is financially detrimental to their own well being. There are so few who have the ability and the bankroll to materially effect them and the cost of their counter measures is so high in lost revenue, that I am amazed that the bean counters have not figured it out!
