Blackjack played by the chart under common 3:2 rules. Playing the way the dealer must (never doubling or splitting, hitting to 17) costs about ten times as much.

What is inside
- 01
Strategy drill
One hand at a time against the published basic-strategy chart. Instant right or wrong, the reason in plain words, a running score. Hard totals are free; soft hands, pairs and a mixed shoe come with the Pass.
- 02
House edge and evening cost
Twelve common bets with the odds and payout behind each edge, and a calculator: stake, rounds an hour and hours in, out comes the average cost and the range most evenings land in.
- 03
The chart, and a pocket card
The full chart to read for free, with why each zone says what it says. Pass holders get a printable pocket card.
