Changing seats mid-shoe in a card game, particularly in games like blackjack, often depends on the house rules of the casino or venue where you're playing. In many places, players are typically allowed to change seats, but it may disrupt the flow of the game and annoy other players. It's best to check with the dealer or casino staff for their specific policies regarding seat changes. If permitted, moving to a different seat can allow you to try a new position or strategy, but it's important to consider the comfort and preferences of other participants at the table.
