About
If you sit at a Blackjack table and your play deviates significantly from basic strategy, you are giving the house a bigger edge and other players at the table will probably make fun of you. Practice this until you can respond to 100 hands in under 1 minute with zero mistakes. It helps to have this memorized perfectly, because there will be many distractions at the table.
