Kas gali paaiskinti tiksliai, kodel kazino laimi ant BJ? Jeigu as visalaika stosiu ant 17 kaip ir dealeris, mano sansai bus lygus, o BJ'ko atveju as laimiu 3:2 o kazino ne, tai taip iseina kad mano sansai geresni.
The number of decks used has a major effect on the player's chance of winning, because it affects the house advantage. (See comparative statistics below.) All things being equal, fewer decks are always more favorable for the basic strategy player. One cause of this is that player blackjack is slightly more likely in single deck blackjack (because blackjack requires two different cards, by removing a card of one type (e.g., a Ten), getting one of a different type (e.g. an Ace) is more likely - and the effect is much bigger in a single deck game than in a multi-deck game), and if the player does have blackjack, the dealer is significantly less likely to have blackjack as well (which is a push), meaning that the player will get paid at 3:2 more often in the single deck game.
In reality, multi-deck games almost always have otherwise better rules than single-deck games. However, card counting is much more effective for single deck games. For illustrative purposes, the statistics below all use the same rules—double after split, no resplits, one card to split Aces, no surrender, double on any two cards, original bets only lost on dealer Blackjack, dealer hits soft 17. The single deck game is much better than double deck, which is significantly better than four decks, while from six decks and up there is very little difference.
