Dealer Hole Card Peeking (Flash)
How it works
A corrupt dealer intentionally exposes the hole card to a confederate player while appearing to check for blackjack or during the deal. The dealer may lift the corner too high, angle the card toward a specific seat, or use a controlled dealing motion that flashes the card value. In exchange for a share of winnings, the dealer provides this inside information that gives the player a massive mathematical edge. The player may also signal other team members at the table.
Where it appears
Blackjack, Three Card Poker, Caribbean Stud, other hole-card games
On the record
Hole carding has been a documented advantage play technique since the early days of blackjack. While most hole carding exploits sloppy dealers rather than corrupt ones, deliberate dealer collusion provides a much more reliable information stream. Professional hole card teams have historically targeted dealers known for sloppy technique.
