The "dealer checks for Blackjack" rule impacts the game by altering the way the dealer handles their upcard when they show an Ace or a 10-value card. Under this rule, when the dealer's upcard is an Ace or a 10, they will immediately check their hole card to see if they have a Blackjack (a total of 21, consisting of an Ace and a 10-value card). If the dealer has a Blackjack, the round ends, and all players lose their bets, unless they also have a Blackjack, in which case the hand results in a push (a tie).
This rule is important because it prevents players from continuing to play their hands or making additional bets once the dealer’s Blackjack is confirmed. If the dealer does not have a Blackjack, the game proceeds as usual, and players can continue to make their decisions based on the dealer's visible upcard.
From a strategic standpoint, this rule is generally beneficial for the casino because it allows the dealer to immediately settle the round if they have a Blackjack, thereby minimizing the risk of players getting paid out for their own Blackjacks if the dealer wins. For players, the rule may slightly decrease the odds of winning, as it reduces the number of opportunities for players with Blackjacks to collect payouts before the dealer checks. In games without this rule, players may continue to play or increase their bets before knowing whether the dealer has a Blackjack.
