Beginner percentage map
Exact dealer bust percentages vary by rule set, number of decks, and whether the dealer hits or stands on soft 17. For learning, start with the directional map: lower dealer cards tend to create more bust pressure, while 10-value cards and aces create stronger made-hand pressure.
Dealer upcardStrategy meaning
2-3Some dealer pressure, but less than 4-6. Player decisions still need hand-strength context.
4-6Often the highest bust-pressure zone, which is why standing on some stiff hands can make long-term sense.
7-9The dealer has more routes to playable totals, so weak player totals often need improvement logic.
10-AStrongest visible pressure. These upcards explain difficult hands like hard 16 vs dealer 10.
Why this works
Expected value
Dealer bust odds affect player risk
When the dealer is more likely to fail over time, the player may not need to take as much card risk. When the dealer is strong, weak player totals may need recovery.
Beginner mistake
Treating probability as certainty
A dealer 6 can still make a hand, and a dealer 10 can still bust. Percentages teach pressure, not guarantees.
