Blackjack Strategy

The Quick Reference

A handful of rules cover most decisions. Internalize these and you'll already be ahead of the average player.

Reading the Game

The dealer's upcard is the single most important piece of information on the table. It tells you what kind of hand the dealer is likely to finish with, which dictates everything about your play.

When the dealer shows 2–6, they're in a weak position. These cards force the dealer to draw, and a draw against a weak start busts often. Your job is to not bust first. Stand on borderline totals (12–16) and let the dealer take the risk.

When the dealer shows 7 or higher, they're likely to make a strong total. A 17 is a real threat, and a 19 or 20 is common. Marginal hands like 13–16 will lose if you stand, so you have to take the risk of hitting and try to improve.

When the dealer shows an Ace, they have the best possible upcard. Casino tables offer insurance here; it's a losing bet over time because the implied odds don't match the true odds. This table doesn't offer it, so simply play the hand on its merits: hit anything below 17, stand on 17 and up.

This logic is what produces the chart. Memorize the chart and you have the logic by reflex.

Betting Systems

Betting systems govern how much you wager from one hand to the next. None of them changes the underlying odds — they're frameworks for managing variance and bankroll, not edges over the house.

Bankroll Management

A bankroll is the money you've decided in advance you can lose. Set it before you sit down, not while you're playing.

A common heuristic is to size your base bet at 1–2% of your session bankroll — enough room to absorb normal variance without going broke on a bad run. A $500 bankroll suggests a $5–$10 base bet, not $50.

Decide a stop-loss and a stop-win before the first hand. Walking away from a winning session is harder than walking away from a losing one; both require the same discipline.

Common Pitfalls

A Note on Card Counting

Card counting is the practice of tracking the ratio of high to low cards remaining in the shoe to time bigger bets to richer decks. It's legal, it works in physical games with deep deck penetration, and it's worth roughly 0.5–1.5% in expectation when done well.

This table uses a real six-deck shoe that reshuffles once about one deck remains, and it resets whenever you reload the page. So a count is technically possible here, but there is very little to do with it. Most of a counter's edge comes from doubling and splitting more aggressively when the shoe is rich in tens, and neither option exists at this table. Treat this as a basic-strategy game: play the chart, and let the count be a curiosity.

The Basic Strategy Chart

Find your hand's total down the left, the dealer's upcard across the top, and play the cell where they meet. This is the standard chart for a multi-deck game where the dealer stands on all 17s, doubling after a split is allowed, and surrender is not offered. It is the right chart to memorize for casino play. The section after it translates every Double and Split cell into the hit-or-stand choice you actually have here.

Cells assume double-after-split is permitted. Played correctly at a table with those options, basic strategy reduces the house edge to roughly half a percent over the long run.

Playing the Chart With Hit and Stand Only

Every cell in the chart collapses to one of two moves at this table. The conversion is mechanical:

• ·Dh (Double, else Hit) — hit. Every hard 9, 10, and 11 and every soft 13–17 is a hit here.
• ·Ds (Double, else Stand) — stand. That is soft 18 against a dealer 3–6; against a 2 the chart already says stand.
• ·P (Split) — play the pair as its plain total using the hard or soft table. The lookup below does that for you.

Giving up doubling and splitting costs the player. Against the same dealer rules, a hit-and-stand-only game carries a house edge somewhere around two percentage points higher than the full-options figure above. That is the honest price of a simpler table, and it is why the bankroll here is play money. The decisions themselves are still worth getting right — hitting a 16 against a 10, and standing a 13 against a 6, are the habits that carry over to any table.
