The 6 is the weakest upcard in the deck, and the strategy chart treats it accordingly. Against a 6 the chart becomes the most permissive version of itself: stiffs that would hit against stronger upcards stand, soft hands that would hit elsewhere double, and pairs that a stronger upcard would not justify come apart into two.

The number behind all of it: per the final total distribution tables computed by Wizard of Odds for six decks, a dealer showing a 6 busts 42.3 percent of the time when the dealer stands on soft 17, and 43.9 percent when the dealer hits it, the highest bust rate of any upcard in their tables. Our piece on the [dealer's final total distribution](https://21trainer.app/articles/dealer-final-total-distribution/) lays out the full tables; this article walks the 6 column cell by cell, the mirror image of our walk through [the 2 column](https://21trainer.app/articles/basic-strategy-vs-dealer-two/), where the chart turns stingy.

Table conditions throughout, matching the app's standard shoe chart: dealer peeks, blackjack pays 3:2, double on any two cards, late surrender where offered, four to eight decks, dealer stands on soft 17 unless stated.

| Hard 9 | Double if allowed, otherwise hit |
| Hard 10 | Double if allowed, otherwise hit |
| Hard 11 | Double if allowed, otherwise hit |
| Hard 12 through 16 | Stand |
| Hard 17 and up | Stand |
| Soft 13 through 17 (A,2 through A,6) | Double if allowed, otherwise hit |
| Soft 18 (A,7) | Double if allowed, otherwise stand |
| Soft 19 | Stand |
| Soft 20 | Stand |
| 2,2 | Split |
| 3,3 | Split |
| 4,4 | Split if double after split is allowed, otherwise hit |

| 9,9 | Split |
| 10,10 | Stand |
| A,A | Split |

One note first. Nothing surrenders against a 6 in any chart, at any deck count, under either soft 17 rule. Surrender exists for hopeless hands against strong upcards, and this column contains none.

## Why every stiff stands

A stiff is a hard 12 through 16, and against a 6 all of them stand. Standing wins exactly when the dealer busts, which happens 42.3 percent of the time per the stands on soft 17 table. Hitting gives up part of that at once, because a player who busts loses no matter what the dealer does, and the player's own bust chances are steep: a hard 12 busts on only four of thirteen ranks, the ten values, about 31 percent, while a hard 13 busts on five ranks and a hard 16 on eight, about 62 percent.

And the draw usually fails to buy a new way to win: on any stiff from 12 through 16, 8 of the 13 ranks either bust the hand or leave it a stiff that still needs the dealer to break. Standing on a stiff loses on average too, because the dealer makes a hand 57.7 percent of the time, but it loses less than hitting. The contrast with the 2 is instructive: a dealer 2 busts only 35.4 percent of the time, the lowest of the low upcards, which is why hard 12 hits against a 2 and stands against a 6. Our [dealer upcard guide](https://21trainer.app/articles/dealer-upcard-guide/) covers the pattern across all ten upcards.

## Why so many soft hands double

The soft block is where the column turns aggressive. Soft 13 through soft 17, five totals, all double against a 6, and soft 18 joins them as a double if allowed, otherwise a stand. Against a 2 the same five totals all hit and soft 18 stands; the difference is entirely the dealer's bust rate.

The reasoning runs through what a soft hand is. An ace counted as 11 means the hand cannot bust on the next card, so doubling costs nothing in safety; what it costs is the option to keep drawing after the one card. That option is worth giving up only when the dealer is weak enough, and a dealer who busts 42.3 percent of the time and finishes on 17 or 18 a further 27.2 percent (16.6 plus 10.6 per the table) is exactly that weak. The mechanics are in our [soft hands guide](https://21trainer.app/articles/soft-hands-blackjack/); soft 18 has its own piece on [why it looks finished and is not](https://21trainer.app/articles/soft-eighteen-blackjack/), and the logic of committing to one card is the subject of [when to double down](https://21trainer.app/articles/when-to-double-down/).

Soft 19 and soft 20 stand in this game. They are already made hands: soft 19 wins or pushes against everything but 20 and 21, and soft 20 against everything but 21. One more card is more likely to weaken a soft 19 than improve it, since only an ace or a 2 helps, so under these rules the extra bet does not pay for the worse hand. The margin on soft 19 is thin, and the rules section below shows where it flips.

## The pairs: eight of ten rows split

Eight of the ten pair rows end in a split against a 6, and several are splits a stronger upcard would not justify. Twos, threes, sixes and sevens split unconditionally here; in the shoe game's 2 column, the 2s, 3s and 6s split only when double after split is allowed. The 6 column even splits 4,4, but only with double after split available; without it, the pair plays as a hard 8 and hits, a condition our piece on [splitting 4s and 6s](https://21trainer.app/articles/splitting-fours-and-sixes/) explains in detail.

The logic is the bust rate working through a second channel. Splitting puts a second bet on the table, which the chart does sparingly against a strong upcard. Against a dealer who busts 42.3 percent of the time, starting two hands instead of one is a good trade even from a mediocre pair, since each new hand plays against that same fragile upcard. For the low pairs, much of the split value comes from hands that develop into doubles afterward, which is why the DAS rule moves these cells at all; the details are in our pieces on [splitting 2s and 3s](https://21trainer.app/articles/splitting-twos-and-threes/) and on [double after split](https://21trainer.app/articles/das-double-after-split/).

Two rows stay out. Fives never split: 5,5 is a hard 10 and plays that exactly. Tens never split either, which deserves its own section.

## Why 10,10 still stands

A pair of tens is a hard 20, and against a 6 the dealer finishes on 21 just 9.7 percent of the time per the stands on soft 17 table. A made 20 loses only to that 21 and pushes against a dealer 20, so per the same table it wins about 80 percent of the time. Splitting would trade it for two hands that each start from a single ten, and two good bets are collectively worth less here than one heavy favorite. Even in this, the most aggressive column, the chart refuses. The fuller argument is in [never split 10s](https://21trainer.app/articles/never-split-tens-blackjack/).

## How the column moves with the rules

In shoe and two deck games the 6 column is stable, with one soft exception. When the dealer hits soft 17, soft 19 against a 6 becomes a double if allowed, otherwise a stand. Everything else in the column stays put. The reason tracks the distribution tables: hitting soft 17 lifts the dealer's bust rate against a 6 from 42.3 to 43.9 percent, and turns some of the dealer's soft 17s into 19, 20 and 21, totals that tie or beat a standing 19, so the thin margin for standing tips toward the double. Our [S17 versus H17](https://21trainer.app/articles/s17-vs-h17/) comparison prices the rule and covers the other cells it moves.

The two deck charts are otherwise identical to the shoe chart in this column. The single deck charts are not: with one deck, hard 8 doubles against a 6, soft 19 is a double if allowed otherwise a stand under either soft 17 rule, and 4,4 splits if double after split is allowed, otherwise doubles the hard 8. Short decks shift borderline cells because each card already dealt, the dealer's 6 included, changes the makeup of the remaining cards far more than it would in a shoe. The practical lesson is ordinary: play from the chart computed for your game. In 21 Trainer you set the deck count, the soft 17 rule and double after split, and the chart redraws to match.

## Frequently asked questions

### Do you hit 12 against a dealer 6?

No. Basic strategy stands on hard 12 against a 6, and on every stiff total from 12 through 16. Standing is a bet that the dealer breaks, and a 6 is the most likely upcard to break, 42.3 percent of the time per the commonly published six deck tables where the dealer stands on soft 17. Hitting a 12 busts on any ten value card and often leaves another stiff, so standing loses less even though both plays lose on average.

### Should you double soft hands against a dealer 6?

Most of them, yes, in a shoe game where the dealer stands on soft 17. Soft 13 through soft 17 all double if allowed, otherwise hit, and soft 18 doubles if allowed, otherwise stands. Soft 19 and soft 20 stand, because they are already strong made hands. The logic is that a soft hand cannot bust on the next card, and a dealer who breaks 42.3 percent of the time makes the one card commitment of a double worth it.

### Do you split 4s against a dealer 6?

In the standard four to eight deck game, yes, but only when doubling after a split is allowed; otherwise hit. The value of splitting 4s against a weak upcard comes mostly from the hands that develop into doubles afterward, so without that rule the pair plays as a plain hard 8. In single deck games the cell is more aggressive still: split if double after split is allowed, otherwise double the hard 8.

### How often does the dealer bust with a 6 showing?

More often than with any other upcard. Per the six deck tables computed by Wizard of Odds, a dealer with a 6 up busts 42.3 percent of the time when standing on soft 17 and 43.9 percent when hitting it, the highest figure in both tables. The bust rate then drops sharply to 26.2 percent against a 7, which is why the 6 column is the most permissive in the chart.

### Do you ever surrender against a dealer 6?

No. No surrender cell appears anywhere in the 6 column, at any deck count, under either soft 17 rule. Surrender is reserved for hands that are hopeless against strong upcards, mostly 15 and 16 against a 10 or an ace. Against the weakest upcard in the deck, every hand is worth playing out.
