Blackjack variants

Blackjack is one of the most common, if not the most common casino games in the world. You can find it in almost any casino, both on land and online. It is played in a similar way internationally, but in some aspects it is treated differently, and it is known that some rules vary between continents, countries, cities and, sometimes, even between neighboring casinos. These rules and how they differ are called rule variants.
Knowledge of these rule variants is very important for two reasons. First, in some hands they will affect your movements. (See Our table of key strategies.) And secondly, they affect your chances of winning the game.
These are variations of the rules:

1. Number of decks: you want to play at the table with the fewest decks as this will increase your chances of winning.

2. Soft 17 or 17 soft: this is a 17 hand that contains AS. In all tables the dealer must be BROKEN up in hand 17. A table in which the dealer has to HIT in soft 17 reduces your chances of winning.

3. Duplication: some tables allow players to duplicate their starting hands, others only allow it in starting hands with a value of 9, 10 or 11, etc.Playing at a table with the "Duplicate" option is of course beneficial for players.

4. Split manually more than once: in some casinos you can split identical cards only once, while in others it is allowed twice or even more. The more chances to leave, the more chances you have to win.

5. Duplicate after split hand: some casinos will allow you to duplicate after split hand . This option favors the player.

7. Surrender: some casinos allow you to surrender and pay only half of your bet.

8. Insurance: in some casinos, you can buy insurance from the dealer's blackjack if your open card is AS. If the dealer finally gets blackjack, you win 2 to 1.

9. Dealer blackjack: you can lose all your bets or only the original dealer blackjack bet.
