I went to a casino recently and sat down at a full table of a 6 deck blackjack game and saw something truly amazing. There was only 1 spot open, and I planned on playing 1 hand and use a bet spread of 7.5:1. Only a few hands in, the count went positive, and the character at first base jumped from 2 hands of $2 each to 2 hands of $100 each and eventually bet up to 2x$300. Furthermore, every time he had a decision to make that was affected by the count, like taking insurance, hitting hard 12 vs 2, and doubling 8 vs 6, he took about 15 seconds to make each decision and appeared at one point to count on his fingers while staring at the discard pile. I wanted to pull him aside and tell him that he was being way too obvious. Instead, I left as soon as the shoe was over and decided to never sit down at a table if I spot him again.
Question: With regard to this particular casino, should I be playing here and much as possible and using a 150:1 myself or will this game get a lot more scrutiny soon? If I wasn't in such a hurry to escape his potential heat, I could have stayed, flat bet, and seen what happened, but I really only have the 1 shoe worth of information. Do casinos really exist that a player can consistently, blatantly count cards and not get banned?
