Blackjack

Publié le par sdgadmin

compter les cartes

  • Blackjack : le but est d’avoir une main plus proche de 21 que le croupier sans dépasser 21.
  • Chaque carte a une valeur dans le comptage :
    • Cartes basses (2 à 6) = +1
    • Cartes neutres (7 à 9) = 0
    • Cartes hautes (10, figures, as) = -1

  • Si le reste du paquet est riche en cartes hautes (10, as), le joueur a plus de chances de faire blackjack et de gagner.
  • Si le reste est riche en cartes basses, le croupier a un avantage plus important.

L’astuce : augmenter les mises quand le paquet est favorable, et miser peu quand il ne l’est pas.
