I've said this before, but I agree with Alan on the last post. Rob's Martingale schtick wasn't going to do anyone any good in and of itself, but the minute percentages he lost with his "special plays" versus optimal play were probably compensated for by increased comps due to the impulsive, erratic profile that his style of play would generate. His style of play may also have reduced seat time, which on negative games would be a positive. His rants about "doing the opposite of what the casino wants" were spot on, I thought. Plus he had the guts to call people out on tipping hand pays and other assorted nonsense.
Unfortunately, he wrapped these basic points with his flag of "I have a unique and special system," which was a tough sell to anyone who knew anything about video poker.
