Doubling, Insurance and Blackjack Surrender
Apart from dealer rules to play, there are several different variations in the rules (link to 5.3.) of the casinos for different types of blackjack games. Most of these rule variations can be seen in blackjack surrendering, insurance and doubling of the hand.
Given below are a few types of rule variations:
Doubling
Doubling is probably the most profitable options for a player and there are several different rules regarding doubling. Several online casinos do not allow doubling at all. Some casinos only allow the players to double on their first 2 cards while there are others who allow doubling on any number of cards. When the player is allowed to double on any cards, the odds are increased by 0.2%.
Also, while doubling down the player will have to double the original bet and can receive an additional card. There are a few casinos that would only allow doubling down if the cards are of certain value like from nine to eleven.
Doubling after a split
Again, this is a very common variation. In this rule the casino would allow the player to double the bet even after the hands have been split. This rule would increase the edge of the player by 0.14%. What splitting means is being able to divide the initial two hands if they are matching into 2 separate hands and then being able to play both of them independently. However, after a split a 21 would not be considered a blackjack.
Also, some casinos would allow the players to keep on splitting if there are additional pairs after the initial hand. There would be a few restrictions on the maximum number of times that splitting would be allowed. The rules about doubling the bet after the hand has been split would be different for every casino.
Blackjack Surrender
Surrender is a rule where the player is allowed to surrender the hand altogether if the cards are not satisfactory. Some casinos would allow the players to surrender the hand before the dealer would check for the blackjack which is known as an early surrender. In other cases, the player would also be allowed to surrender after the dealer checks for blackjack which is known as a late surrender. This can make a huge difference to the player in a very favorable manner.
Insurance
Insurance is one of the most common and yet the least understood rule. How it works is that the dealer would turn an up card which would be ace. Then the dealer would offer the player insurance. The insurance bet would be half of the original bet or less. After this, the dealer would check to see if he/she has a blackjack. If the dealer has a blackjack, the bet would be paid at 2 to 1. However, if there is no insurance, the player would lose the original bet as well as the insurance bet.
Whether or not insurance is allowed and the amount which has to be made as an insurance bet would differ for every casino.
