Split

A split in blackjack is an option available to players when their first two cards are a pair (two cards of the same rank). Instead of playing the two cards as one hand, the player can split them into two separate hands. This move doubles the original bet, as each hand now plays independently. Splitting allows players to capitalize on favorable situations and potentially increase winnings.

Splitting is a key strategic move in blackjack, but knowing when and what to split can drastically affect your chances of winning. It is not always the best choice, and poor splits can increase the house edge. That’s why it’s critical to understand the rules and strategies around splitting.

Key Details of the Split in Blackjack

The split changes the game by allowing you to create two hands from one, but it comes with increased risk and opportunity.

Splitting requires doubling your original bet (one bet per hand)
After splitting, each hand is played separately with normal hit, stand, double down, or sometimes re-split options
Most casinos allow re-splitting up to 3 or 4 times, depending on house rules
Aces split usually receive only one additional card per hand, with no further hits allowed
Splitting can reduce the house edge when done with the right pairs (like 8s or Aces)
Incorrect splitting increases house edge and risks larger losses

How Does the Split Work?

When you receive two cards of the same value (e.g., two 8s, two Kings), you have the option to split:

Announce your intent to split before taking any further action.
Place an additional bet equal to your original wager.
Your two cards become the starting cards for two separate hands.
The dealer deals a second card to each new hand.
You play each hand independently, making decisions to hit, stand, or double down according to standard rules and strategy.

Some casinos restrict or modify splitting rules, such as not allowing split Aces to be re-hit or limiting the number of splits allowed.

Examples of the Split in Action

Example 1:

Initial hand: 8♠ and 8♦, bet $50
Player splits, placing another $50 bet for a total of $100 in play
Dealer deals a 3 to the first 8, total 11—player doubles down, bets $50 more
Dealer deals a King to the second 8, total 18 — player stands
Outcomes: First hand wins with 21 or dealer bust, second hand pushes or wins, depending on dealer’s total.

Example 2:

Initial hand: A♣ and A♥, bet $25
Player splits, bets another $25
Dealer deals a 10 to each Ace for two blackjacks (depending on house rules, these may count as 21 or blackjack)
Player collects winnings on both hands, often paid at 3:2 or 1:1 depending on rules.

Tips for Using the Split in Blackjack

Always split Aces and 8s — this is standard basic strategy.
Never split 10s or 5s — playing 20 or doubling on 10 is better than splitting.
Pay attention to dealer’s upcard — it can influence whether splitting is advantageous.
Know your casino’s rules on re-splitting and hitting after splitting Aces.
Use splitting to maximize winning potential but avoid overextending your bankroll.
