Blackjack Wikipedia
Note that a ten-value card dealt on a break up ace (or vice versa) will not be counted as a blackjack but as a gentle 21. Most of the house’s edge comes from the fact that the player loses when both the player and dealer bust. Blackjack gamers using basic technique lose on common less than 1% of their action over the long run, giving blackjack one of the lowest edges within the casino. The house edge for games where blackjack pays 6 to 5 instead of three to 2 increases by about 1.4%. Player deviations from basic strategy additionally increase the house edge. If a player’s first two playing cards are of the identical denomination, corresponding to two jacks or two sixes, they might select to treat them as two separate arms when their turn comes round.
