Hello Captain,
Very interesting posts. But I do have a few comments about your tells. When a dealer is using a mirror peeking device to check for blackjack he can't see anything underneath if there is no blackjack. The way casino cards are set up you will notice that 10 valued cards are only marked on 2 corners but higher up than the other cards. Aces have there symbol in all 4 corners but only higher in 2 of them. When the dealer checks for blackjack with a 10 up they will put the card in the device straight in as they sit on the table. If there is anything other than an ace it will show white only. If there is an ace up they will spin the cards horizontal and put it into the peeker that way. If there is no ten than only white will show. The cards for casinos are designed for these peeking devices to take the human element out of it. All other cards other than 10 value and aces have there corner symbols printed much lower so they do not appear in the peeker window. As I'm sure you have seen there are even some peeking devices that are just push button with a red or green light to tell if there is blackjack or not. I do not refute there are ways to take advantages of weak dealers, especially if they are manually liting cards to check for blackjack. But to say you can catch tells on the peeking devices, without saying you're holecarding is something that is hard to fathom. I wish you continued luck, but I hope your tells reading also consists of other things based on seeing cards or capitilizing on certain shuffles, otherwise I think your info may be flawed.
Another very good post, and yet another very good argument.
And you are 100% correct about the cards, and the peeker window. I will assume you either are a dealer (past or present) or have access (now or in the recent past) to the standard BJ table.
Using this assumption, then I can conclude that you are also aware of the flaws of the peeker window:
As hard as casinos try to remove the human element...it will always exist under current conditions (machine-top-deal exception). Even the most veteran dealer...sometimes more-so than the rookie, will make mistakes...very simple mistakes, and undetectable to most. How many times have you watched a dealer have an ace-up , and then look to the peek window...only to have to shift the card, and look again? Same holds true for the Ten-up.
The reliablility of the "peek" window is contingent on card-placement....a human element.
Do this excerciseL Take a piece of chalk, and mark to lines on the end of your table.... then simulate a 2-deck shoe..... each time you get a T/A...place the hole-card over your PW (chalk-lines)...do it at normal speed...not too fast, not too slow. Then...count how many times you miss the mark.
Some casinos even have a small "guider"...but even that does not stop the inevitable.
As for the overall usage of tells...they are dependant on many factors. The dealer just happens to be the largest factor. My reasons for focusing on the dealer in this thread, is that is what was asked of me...... Had someone, for instance, asked me about the dealer cut, and that tell...then this thread would have went in a whole different dirrection.
Nice observation.
