I played BJ in the casino on two evenings (night 1 and 3). Ended up getting a little back on the second night. All in all, not a high price paid for the entertainment. I asked at the cage when I cashed out and was told I had earned a little over 3,000 points. I'm not sure if that was a "real time" figure or not. I probably put in less than 6 hours of play total. I was playing at the $25 table, and I can't recall seeing quite this number of people (with several hundred or more "in hand") that didn't know how to play the game. Examples: Standing on your A-A-5 against an 8, and losing. Doubling (yes, you heard that right) your 7's against a 9.. and winning. Splitting 5's against a 5 (and losing). It just never stopped. Internally, my eyes rolled over and over. I was shocked to see that they offered surrender - I play two hands, averaging $50/hand. Upon getting a 16 and 17 against the dealer's A, I asked, and they said YES. I surrendered. I don't think anyone ever takes them up on it, but the pit boss explained it to them. I saved half my bet that hand. I would go on to surrender twice more (mostly with "better than it would have been" results). BTW, it would seem they don't have, or at least don't often use, purple chips. If they did - the fellow with a FULL TRAY of blacks could have used them last night at first base. Even he hesitated on many obvious basic strategy plays. I'm the only one who hits my 12 on the dealer 2 or 3. I'm the only one who hits my A-7 vs dealer 9-10-A (take a shot!), etc...
Noticed this also, was going to hop into the table with the big winner ( had 7-8 K in blacks in front of him). After watching for a few minutes a kept going as no at the table had even a basic clue as to what they were doing.
