The Mathematics Of Blackjack
Beginner players have no way of knowing if the dealer has a card worth ten points face-down under an ace. Card counters however have a better idea and can use their information to make money on this bet. You may even want to wait a few weeks until your bankroll has grown before playing real-money blackjack.
Of course, not everybody is going to fly to Vegas just to play the best blackjack games. But again, the key is that you learn the rules so you can spot favorable games in your area. Double down – You want to be able to double down on any total. This lowers the house edge by 0.25% in comparison to only doubling on 9 to 11. The downside to this low variance is that you also won’t win very big payouts in relation to your bet size.
Even if the dealer has a weak card like a five, don’t split tens. You already have a strong hand, 20, so why risk more money to potentially lose it all if the dealer goes on to get lucky? Chances are you already have the winning hand, so leave it at that. After the dealer finishes, scores are tallied and the round is over.
Even at the lowest blackjack stakes, you’ll need a massive bankroll to avoid risk of ruin in real money games. If the dealer is dealt a natural blackjack with their first two cards, the down card is turned face up, and all players that don’t also have a natural blackjack automatically lose. If the dealer either has to stand, all players that beat the dealer with a higher total win. A double down can only be applied if you’re dealt a total of nine, ten, or 11. Splitting pairs takes a paired hand and splits it into two separate hands, doubling your wager but allowing only one more card on each.
Shopping for the lowest house edge is easier in online blackjack, since you can quickly navigate from casino to casino. The Las Vegas casinos El Cortez, Treasure Island, and Boulder Station offer excellent blackjack tables. El Cortez is especially good because they have low-stakes blackjack tables with a 0.30% house edge. Most brick-and-mortar casinos feature some unfavorable rules that push the house edge towards 2%. But there are also casinos with good rules that cater to blackjack players. Your chances of winning a given blackjack hand are 46.36% when not including ties.
You have to be great at watching the cards as they’re shuffled and know card counting on top of this. Some advantage players also try to avoid making any play that’s obviously bad from a strategy perspective (e.g. doubling down on 7 against a dealer’s 10). Such plays make it easier for casinos to tell what’s going on and determine that one of their dealers is a flasher. These dealers also peak at their hole card whenever their upcard is an ace or 10 value. They do this to check for a natural blackjack, which would automatically end the round. The advantage to playing for progressive blackjack prizes is that you don’t need any skill to win.
