I think In Blackjack, dealers deal cards in a specific manner to ensure fairness and randomness. They typically use a shuffled deck, deal cards from the top, and follow a standardized procedure to reveal their own hand. Common mistakes to avoid when dealing include failing to shuffle the deck properly, dealing cards out of sequence, revealing too much information about the deck, and making procedural errors that can affect the game's outcome. Dealers must be vigilant and follow casino protocols to maintain the integrity of the game.
