Yes ... and obviously at a $5 table I wasn't playing to make a living. It's an interesting way to pass the time when you're stuck there for a conference anyway (back then I went to Networld/InterOp every year). My main point was really that if you want to exploit any system, focus on the weakest link. Blackjack is played against the house so in the long term, the house will win a small percentage of the amount played.

Here's one bonus observation that I learned the first time I was in Vegas - the papers that are handed out inside the convention center doors are generally related to the conference you're attending. The papers that are handed out outside the doors are NOT.
