The usage of “surrender” is different in each online casino, and the biggest difference is between “early surrender” and “late surrender”; “late surrender” means that the player cannot “surrender” when the dealer has blackjack. Late Surrender” refers to the fact that a player cannot ‘surrender’ when the dealer has blackjack, which is the exact blackjack situation when the dealer turns over a name card and a concealed card, and the player can choose whether or not to ‘surrender’. The player can choose whether or not to “surrender”. Games in which the dealer has a concealed card exist in almost every game, and games in which there is no concealed card seem to be non-existent. Definition of “Surrender”: To give up the game after getting two cards on the table, generally players just need to draw a line with their hands on their chips, that is to say surrender to the dealer, then the dealer will take away half of your chips, and the round is over and you can't win or lose at the poker table. A few blackjack games have a win-half rule, but few casinos use it; however, the advantage of surrendering is that you lose half of your chips, but the disadvantage is that you could have won or tied the game if you hadn't surrendered, and the disadvantage of surrendering is that you don't have the advantage of losing half of your chips. The “surrender” rule in blackjack is a very vague rule for many players, with a few not knowing about it, and the vast majority of players who do know about it have no way of using it.
