I am a relative newcomer to counting, and have no previous experience with MindPlay. This weekend at Grand Casino Coushatta in Louisianna, they used an under-the-table sensor to track each wager. The dealer would hit a button next to the shoe before the start of each hand, which she said registered the chips in each betting square. I felt under the table, and there was a wired sensor under each betting position. Is this the MindPlay system I've seen mentioned in other posts? If so, I don't see any way in which this system could detect the unused cards in the shoe (as some seemed to suggest). Of course the system could be used to correlate betting swings with observations from the eye-in-the-sky, but to actually detect the cards in or coming from the shoe...I don't see how that would happen. Is my undertanding correct, or am I missing something?
