Upcard

In blackjack, the upcard refers to the card the dealer reveals face-up at the start of each hand. It’s one of two cards the dealer receives—the other remains face-down and is called the hole card. The upcard plays a key role in shaping your decisions at the table. It can influence whether you hit, stand, double down or surrender, depending on your hand value and the dealer’s potential strength.

Strategic blackjack players know how to read the upcard and adjust accordingly. A dealer upcard of 2 through 6 is considered “weak” because the dealer is more likely to bust, while a 7 through Ace is seen as “strong,” prompting more conservative play.

Key Details of the Upcard (including odds, house edge, payout if relevant)

The dealer’s upcard doesn’t directly carry odds or payout values, but it massively influences strategy and the house edge.

A weak upcard (2 through 6) increases the dealer’s chance of busting—roughly 35% to 42% depending on the card.
A strong upcard (7 through Ace) reduces the bust potential—down to 17% with an Ace.
Basic strategy is built around countering the dealer’s upcard to maximize player returns.
Correct strategic play based on the upcard can lower the house edge to as little as 0.5%.
Misplaying based on the upcard can swing the odds dramatically back in favor of the house.

How to Bet Based on the Dealer’s Upcard in Blackjack

Unlike craps where bets are placed on specific outcomes, blackjack doesn't allow bets on the upcard. But it directly influences how you bet on your own hand. Your decision-making—whether to hit, stand, double, split or surrender—is guided by the dealer’s upcard strength.

For example:

Against a 5 or 6 upcard, players will often stand on lower totals like 12 or 13 because the dealer has a high bust probability.
Against an Ace, most players avoid doubling unless they have a strong hand, like 11.

How Does the Upcard Work?

At the start of a blackjack hand:

The dealer gives each player two cards face-up.
The dealer also gets two cards—one face-up (the upcard), one face-down (the hole card).
The upcard is visible to everyone and acts as the strategic anchor for the round.
Based on the upcard, players use basic strategy to decide how to play their hand.
Once all player actions are complete, the dealer reveals the hole card and finishes the hand.

Examples of the Upcard in Action

Example 1:

Your hand: 10♦6♣ (total = 16)
Dealer upcard: 5♠
Strategy: You stand, even though 16 is weak, because the dealer is more likely to bust with a 5 upcard.

Example 2:

Your hand: 8♦3♠ (total = 11)
Dealer upcard: 6♥
Strategy: You double down, as the 11 is strong and the dealer has a weak card.

Example 3:

Your hand: 9♥7♦ (total = 16)
Dealer upcard: K♠
Strategy: You hit, as the dealer is strong and you’ll likely lose unless you improve.

Tips for Betting Based on the Upcard

Learn Basic Strategy Charts: These are built entirely around upcard logic.
Avoid Insurance: Especially when the dealer shows an Ace. Statistically, it’s not worth it.
Don’t Panic at Strong Upcards: A 10 or Ace doesn’t mean an auto-loss—just play tighter.
Use Composition-Dependent Strategy: Some hands like 16 made with 3 cards can be played differently than a 10-6 combo.
Pay Attention to Dealer Bust Odds: Upcards like 4, 5, and 6 are where the dealer is most vulnerable.
