What this page used to say. An earlier version was a first-person confession: up $4,200 after three hours at an XTP Casino blackjack table, the narrator held 20 against the dealer’s 6, doubled on a stranger’s whisper, watched the dealer draw a 5 and a 10 to make 21 and lost $8,400 — “rent, car payment, savings”. Two months later he returned to “the same table, same dealer”, played basic strategy and became “the consistent winner”. XTP is an online casino, so the felt, the whispering neighbour and the same dealer were invented, and the hand itself does not add up. The story cannot be checked and has been removed.
The hand does not add up
When you double, you receive exactly one more card. On a hard 20, every card from 2 upwards busts you immediately; only an ace improves it, to 21, and an ace comes roughly once in 13 cards (about 7.7%). So in about 92% of cases the narrator would have lost before the dealer turned a card. In the remaining case he holds 21; the dealer’s 6 + 5 + 10 also makes 21, and the hand is a push, not a loss. Neither branch matches the story. Basic strategy never doubles a hard 20: you stand, and against a dealer 6 a 20 is one of the strongest positions in the game.
Basic strategy against a dealer 6
Basic strategy is the mathematically best play for each of your hands against each dealer upcard, worked out from the game’s rules. A dealer showing 6 busts more often than with most other upcards, so the strategy stands on stiff totals and doubles where one card helps most. Typical decisions for a multi-deck game in which the dealer stands on soft 17 (check the chart for your game’s exact rules):
| Your hand | Basic strategy vs dealer 6 | Why |
|---|---|---|
| Hard 20 (for example two tens) | Stand | almost any extra card busts you |
| Hard 12 to 16 | Stand | let the dealer carry the bust risk |
| Hard 9, 10 or 11 | Double | one card is likely to make a strong total |
| Soft 17 (ace + 6) | Double (hit if doubling is not allowed) | one card cannot bust a soft hand |
| Pair of 8s | Split | 16 is a poor total; two hands starting with 8 are better |
| Pair of 10s | Stand | 20 is already a strong hand |
What the strategy costs, and what guessing costs
With basic strategy the house edge is roughly 0.5–1%, depending on the rules: the number of decks, whether the dealer hits soft 17, and above all what a blackjack pays — 6:5 instead of 3:2 raises the edge noticeably. Playing on hunches and tips gives away several percent. Example at $25 a hand and 60 hands an hour, i.e. $1,500 staked per hour:
| Way of playing | House edge (approx.) | Expected loss per hour |
|---|---|---|
| Basic strategy, good rules | 0.5% | $7.50 |
| Basic strategy, weaker rules | 1% | $15 |
| Guessing and tips (example) | 3% | $45 |
Note what the table does not contain: a winner. Basic strategy lowers the cost of playing; it does not turn blackjack into income. The old page’s claim that the narrator became “the consistent winner” is not what the maths predicts, and its line that basic strategy cuts the edge “from 2% to 0.5%” depends entirely on the rules and on how badly someone played before.
The real mistake was the stake
The story’s worst decision was not the double but the money: rent, a car payment and savings on a single hand. Gambling money must be money you can lose. And the size of a bet is decided before the session, not raised after a winning streak when you feel “invincible”. At a crypto casino, remember that deposits are blockchain transfers that cannot be reversed, and that a balance held in a coin also moves with its price.
One fact the old page left out: according to XTP’s own list of accepted countries, players in Finland may sign up, while players in France, Poland and Greece may not.
A practical takeaway. Learn basic strategy for your game’s exact rules and keep the chart open while you play. Choose a fixed stake, never play with money meant for bills, never gamble on credit, and set deposit, loss and time limits in your account. If a loss makes you want to win it back at once, stop and contact your national gambling support service.
What anger after a loss does to the next bets is examined in a roulette session after a losing run, and a charm that was supposed to explain a big win in a toilet-paper “lucky charm” and its $12,000 claim.
Frequently Asked Questions
Should you ever double on 20?
No. Only an ace improves a hard 20, and every other card busts it. Basic strategy always stands.
What is the house edge in blackjack with basic strategy?
Roughly 0.5–1%, depending on the rules. Games that pay 6:5 for a blackjack are noticeably worse than games that pay 3:2.
Can basic strategy make me a winning player?
No. It is the cheapest way to play, but the house still keeps a small edge in the long run.
One bad hand is a lesson about the stake, not about luck: play the chart, play with money you can lose, and stop at the limit you set.
