This brings us to statistical realization that over 2 thirds of your blackjack winnings at will come from these 2 hands (Ace 10 and 10 10). Further down chain, bulk of rest of your winnings will come from only 5 more hands - 11, 10 9, 10, Ace 9, and Ace 8. That's why you must burn in strategies for these hands because they are ones that will make you money. If we are talking multiple decks always double down on 11 if dealer is showing 10 or less. The general case - always double 10 if dealer is showing 9 or less. Always stand on hard and soft 19. Always stand on soft 18, except if dealer is showing a 3 through 6, where you should double down. Always hit when dealer is showing a 9, 10 or Ace but stand on 2, 7, and 8.

Now bad news - following hands are responsible for vast majority (almost 85%!) of your losses. Beware of hard 12, 13, 14, 15, 16, and 17. The hard 12 through 16 hands are long term loseing hands whatever strategy you adopt. The overall message? Gear basic playing strategy into your head so you can play it without thinking - know what to do when winning hands appear. Use money management to supplememnt this - bet more when deck is still heavy in tens and Aces (card counting per se is frowned on, of course, but you sould always have some grasp on what's already been played!). This is simplest way to turn blackjack odds in your favour, and ensure you leave casino with more money than you went in with! Good luck!
