Playing on some fake blackjack tables for our company's Christmas party, I started wondering about dealer systems. Do casinos have a simple set of rules that blackjack dealers are to follow? Say, if hitting one more time on your own hand, the dealer's, might be safe a lot of the time, but you've already beaten half the table, it would be better if you don't hit and pay out half the table rather than hitting, busting and paying out the whole table. I'd be astonished if there weren't several such simple systems for blackjack dealers to follow, all with their own names, special rules, advantages and disadvantages. Unfortunately but unsurprisingly, a quick web search shows up lots of results for player systems rather than dealer systems.
I also gained some respect for people who are able to count cards, even in a very simple system. Those cards come quickly on a busy table. If you're able to keep track of a deck score by registering each card, counting up or down and still keep track of your own hand, deciding whether to hit or stay based on the deck score, your cards and whether you still need to beat the dealer, and do it all quickly enough not to raise suspicion, my hat is off to you, sir.

PS - If systems exist for the dealer, they're buried under a lot of chaff.
PPS - It wouldn't need to be secret information for the casino, though. They'll win regardless.
