Deck & Dealing
Number of Decks
Fewer decks = better for player. Single deck is best but often has worse other rules.
Dealer Hits Soft 17
H17 = dealer hits on A+6. Bad for you. S17 = dealer stands. Better for you.
H17
Penetration
How deep into the shoe before reshuffling. Deeper = better for counters.
Player Options
Double After Split (DAS)
Can you double down after splitting a pair? Most casinos allow this.
Double Down Restrictions
Some casinos only allow doubling on certain totals.
Surrender
Can you forfeit half your bet on bad hands? Early surrender is rare but valuable.
Resplit Aces
Can you split aces more than once if you get another ace?
Hit Split Aces
Can you take more cards after splitting aces? Usually no.
Payouts
Blackjack Payout
3:2 is standard. 6:5 adds ~1.4% to house edge - AVOID these tables!
Dealer Peeks for Blackjack
US style: dealer checks for BJ before you play. European: no peek (riskier doubles).
Rule Impact
Bad rules compound. A 6:5 game with H17 and no surrender can have 2%+ house edge - you cannot beat this with counting. Always scout tables before playing.
