How to Play Your Hands Against a Dealer’s 10 Upcard
When a dealer shows a 10 upcard at online or live blackjack, she or he is in the driver’s seat because they have a 77% chance of getting to a final hand that totals 17 through 21 and only a 23% chance of busting. A ten, therefore, is a very strong dealer upcard. This means we have to be more aggressive when we are a dealt a stiff hand (hit rather than stand) and less aggressive when we are dealt a two-card soft hand (hit rather than double down).
