Questions people ask

What is basic strategy in blackjack?
The best move for every hand against every dealer up-card, worked out by maths. Following it exactly brings the house edge down to about half a percent with good rules.
Does basic strategy change with the rules?
A little. Whether the dealer hits soft 17, whether you can surrender and whether you can double after splitting change a handful of moves. The chart here updates for the rules you pick.
Should I ever take insurance?
No, not with basic strategy. Insurance pays 2 to 1 on something that happens about 4 times in 13, so it loses about 8% of what you put on it. Only card counters take it, when the count is high.
When should I split?
Always split aces and 8s. Never split 10s or 5s. Split 2s, 3s, 6s, 7s and 9s against weak dealer cards; the chart shows exactly which.
Is it cheating to use a strategy chart?
No. Many casinos even let you look at a card at the table, as long as it doesn't slow the game down.
