Since you asked nicely, the following is a well known case which got caught. This happened in 1999. Highly likely that somewhere out there, there have been groups that perfected the technique and never got caught.
Here´s basically how the team operated:
2 men worked as card counters. They began playing Mini-Baccarat, betting with low stakes and noting the cards played (this is a common enough practice in baccarat- nothing wrong in doing this as long as you can do it in your head).
When it was time to shuffle the deck, the Card Counters stopped betting and left the table. The dealer, also part of the team, set up a new shoe of cards, but shuffled in a pre ordained way, which gave other members of the team an edge against the house. Then 9 more players from the team sat down at the table. Because they knew the card order , they bet big on each hand – up to $3,000 on a hand and won more than $100,000.
