Blackjack has the best odds of any game on the casino floor — and the shortest distance between playing it well and playing it badly. Everything here is worked out rather than asserted: the right play for every hand, what a set of table rules actually costs you, and where the game is worth playing.
Three ways in. Pick the one that sounds like you.
Played correctly, a normal six-deck game costs about 0.46% — better than any other game in the building. Two rules can take that to over 2% without changing anything you can see happening at the table.
You act first. Bust, and your bet is gone before the dealer turns a card — that single ordering is where the entire house edge comes from, and it is why every decision you make is really a question about the card the dealer is showing.
A dealer showing a five or a six busts more than four times in ten. Showing an ace, fewer than two times in ten. Same deck, same rules, wildly different hands to be sitting across from.
Dealer bust rates by upcard, six decks, dealer standing on soft 17: 2 35.4% · 3 37.4% · 4 39.4% · 5 41.6% · 6 42.3% · 7 26.2% · 8 24.5% · 9 22.8% · 10 23.0% · A 16.7%.
Table rules are not decoration. The payout on a natural is the one that matters: a table paying 6 to 5 instead of 3 to 2 costs 1.36% on its own — roughly three times the entire house edge of the game you were about to play, and nothing you do with the cards gets it back.
Against a six-deck game where the dealer stands on soft 17: blackjack paying 6 to 5 costs 1.36%, a dealer who hits soft 17 costs 0.22%, no double after split costs 0.12%, doubling restricted to 9–11 costs 0.10%, and late surrender gives back 0.07%.
