response: Cool!  Have you seen card counters?  They try to reduce the casino house edge, and they do that by keeping count of all the high and low cards they see.
original_response: Cool!  My aunt was a dealer for a long time.  Ever catch anyone counting cards or anything like that?  I imagine it's pretty tough.
history: Hello there, are you familiar with any card games? Oh hello!  Well I know about blackjack, it's also called twenty one.  There's usually a dealer and several players.   The players compete against the dealer, one at a time.  The players don't compete against each other. Nice, I like blackjack as well because I'm a dealer, I'm still not a master though
knowledge: Card counters are a class of advantage players, who attempt to decrease the inherent casino house edge by keeping a running tally of all high and low valued cards seen by the player.
