Blackjack Basic Strategy: Your Most Important Tool
Basic strategy is a set of mathematically optimal decisions for every possible combination of your hand versus the dealer's upcard. It was first published in 1956 by Roger Baldwin, Wilbert Cantey, Herbert Maisel, and James McDermott in the Journal of the American Statistical Association. Every decision in basic strategy is derived from computer simulations of millions of hands.
Why Basic Strategy Matters
Without basic strategy, the average blackjack player faces a house edge of approximately 2% to 4%. With correct basic strategy, that edge drops to 0.28% to 0.5% depending on the specific rule set. Over a session of 500 hands at C$10 per hand (C$5,000 total wagered), the difference between using and ignoring basic strategy is roughly C$75 to C$175 in expected losses.
Basic strategy is not just for experts. A single printed chart covers all decisions for a standard 6-deck game. It is legal to use at online casinos, and even at most live tables. Memorising it completely takes a few hours of practice. Using it consistently is the single most impactful thing a blackjack player can do.
Core Basic Strategy Rules
The full basic strategy chart has dozens of entries, but these core principles cover the most common situations:
- Always stand on hard 17 or higher, regardless of the dealer's card.
- Always hit on hard 8 or lower.
- Double down on hard 11 against any dealer upcard from 2 through 10.
- Double down on hard 10 against dealer 2 through 9.
- Always split Aces and 8s. Never split 10s or 5s.
- Hit soft 17 (Ace + 6) unless doubling is available against dealer 3–6.
- Never take insurance — the house edge on insurance is approximately 7.4%.
- Surrender hard 16 against dealer 9, 10, or Ace if surrender is available.
Blackjack House Edge: Understanding the Numbers
The house edge in blackjack is not fixed — it varies significantly based on the specific rules of the game you are playing. Understanding which rules favour the player helps you choose the best tables.
| Rule | Effect on House Edge | Player-Friendly? |
|---|---|---|
| Blackjack pays 3:2 | Reduces edge by 1.39% | Yes — always seek 3:2 |
| Blackjack pays 6:5 | Increases edge by 1.39% | No — avoid these tables |
| Dealer stands on soft 17 (S17) | Reduces edge by 0.22% | Yes |
| Dealer hits soft 17 (H17) | Increases edge by 0.22% | No |
| Double after split allowed | Reduces edge by 0.14% | Yes |
| Late surrender allowed | Reduces edge by 0.07% | Yes |
| Re-split Aces allowed | Reduces edge by 0.07% | Yes |
| Number of decks (1 deck) | Reduces edge by 0.48% vs 8 decks | Yes — fewer decks = lower edge |
Casino Days and JackpotCity both offer games with 3:2 blackjack payouts and dealer stands on soft 17. These are the two most important rules to check before sitting down at any table. A 6:5 blackjack payout alone wipes out nearly all the benefit of using basic strategy.
Card Counting: The Myth and the Reality
Card counting is the practice of tracking the ratio of high to low cards remaining in the shoe to gain a statistical edge over the house. It was made famous by the MIT Blackjack Team and popularised by books like Bringing Down the House and the film 21. At physical casinos with shallow shoe penetration, skilled card counters can achieve an edge of 0.5% to 1.5%.
Why Card Counting Does Not Work Online
Card counting is ineffective at online blackjack for two reasons. First, RNG blackjack games shuffle the virtual deck after every single hand, meaning there is never any shoe penetration to exploit. Second, live blackjack tables either use continuous shuffling machines (CSMs) that shuffle discards back into the shoe continuously, or multi-deck shoes with frequent manual reshuffling at the cut card.
In a game with zero shoe penetration, card counting provides zero edge. The concept simply does not apply. Online blackjack is better approached as a game of skill through strategy optimisation, table selection, and bankroll management — not counting.
Blackjack Variants at Canadian Online Casinos
Beyond classic blackjack, Canadian online casinos offer a rich variety of rule modifications and game formats. Here are the most important variants to know.
Infinite Blackjack (Evolution Gaming)
Infinite Blackjack allows an unlimited number of players to join a single live dealer table simultaneously. Every player receives the same initial two-card hand from the dealer but makes independent decisions. Side bets include Any Two 3s (pays 100:1), Hot 3, and Bust It. The minimum bet is typically C$1, making it the most accessible live blackjack option for budget players. Casino Days and 888casino both carry Infinite Blackjack 24/7.
Lightning Blackjack (Evolution Gaming)
Lightning Blackjack applies a random multiplier of 2x, 3x, 5x, 10x, or 25x to winning hands. The multiplier is revealed before each round. To fund these multipliers, the player pays an additional fee on each winning bet. Lightning Blackjack suits players who accept slightly worse average odds in exchange for the chance to hit a big multiplied win on a single hand.
Free Bet Blackjack (Evolution Gaming)
Free Bet Blackjack gives the casino a free bet on all hard double-down opportunities (9, 10, and 11) and all pairs. You do not risk additional money on these splits and doubles — the casino funds them. In exchange, if the dealer busts with 22, all remaining hands push rather than winning. Free Bet Blackjack slightly favours players who frequently land double and split opportunities.
European Blackjack
In European Blackjack, the dealer does not take a hole card until all players have completed their hands. This means if the dealer has blackjack, you can lose doubled or split bets in addition to your original bet. The rule increases the house edge slightly compared to American Blackjack, where the dealer peeks for blackjack before players act.
Spanish 21
Spanish 21 removes all four 10-value cards (not face cards) from the deck and compensates with liberal rules: player blackjack always beats dealer blackjack, player 21 always wins, late surrender is allowed, and bonus payouts apply for specific 5, 6, and 7-card hands. Despite the removed 10s, the house edge with optimal strategy is comparable to standard blackjack at around 0.4%.
Frequently Asked Questions
With correct basic strategy, the house edge in online blackjack is typically 0.5% or less, making it one of the lowest house-edge games in the casino. Some blackjack variants have edges as low as 0.28% with optimal rules. Without strategy, the house edge rises to 2% to 4% for average players.
Yes. Basic strategy is a mathematically proven optimal decision for every possible hand combination against every dealer upcard. It does not guarantee wins on individual hands, but over thousands of hands it reduces the house edge to below 0.5%. Basic strategy charts are freely available and legal to use.
Card counting is not effective at online blackjack. RNG blackjack shuffles the deck after every hand, removing any shoe penetration. Live blackjack uses continuous shuffling machines or multi-deck shoes shuffled frequently, making card counting impractical. Online casinos also use 6 to 8 decks, which greatly reduces any counting edge.
Popular variants include Classic Blackjack, European Blackjack, Atlantic City Blackjack, Pontoon, Perfect Pairs, Double Exposure, Spanish 21, and live variants like Infinite Blackjack, Lightning Blackjack, and Free Bet Blackjack. Casino Days and 888casino carry the widest selection with 50+ variants.
Live blackjack uses a real human dealer streaming from a professional studio. Cards are physically dealt on a real table. RNG blackjack uses a computer to simulate the game. Live blackjack offers a more authentic experience, while RNG blackjack allows unlimited time per decision and is available in free play mode.
Infinite Blackjack by Evolution Gaming allows an unlimited number of players to join a single live dealer table simultaneously. Every player receives the same initial two-card hand but makes independent decisions. Side bets include Any Two 3s, Hot 3, and Bust It. It offers a lower minimum bet than most private live blackjack tables.
No. Insurance is a side bet that pays 2:1 if the dealer has blackjack when showing an Ace. However, the house edge on insurance is approximately 7.4% in a standard 6-deck game. Basic strategy always says to decline insurance, including when you hold a blackjack yourself (even-money). Over time, taking insurance costs you money.
Casino Days offers the widest overall blackjack selection with 50+ variants and the full Evolution live blackjack suite. JackpotCity is best for Microgaming RNG blackjack, while 888casino offers the most dedicated live blackjack lobby with private table options. For strategy players, always prioritise tables with 3:2 blackjack payouts and dealer stands on soft 17.
