The Backdoor Flush in Poker


In poker, the term backdoor flush refers to a player who manages to hit all the cards necessary to achieve a straight or a flush, and does so with a large statistical advantage. The player must also have a large statistical lead to accomplish this goal. In this article, we’ll discuss all the rules surrounding the backdoor flush, including the importance of making the right move on the turn or river, and how to spot duplicacy on the board.


If you’re a new poker player, you might wonder whether to all-in. While the move has its merits, it’s not always the best strategy. If you’re not familiar with all of your opponents’ previous actions, you need to pay attention to your opponents’ expressions to know whether or not they’ll bluff. If they don’t, you might find yourself in a bad position.


In poker, the battle for the blinds begins with every hand. A player must steal the blinds when they can and adjust ranges based on their reads. This information is best obtained by using a HUD and observation. The general rule of thumb is to attack the blinds in the opposite manner as the opponent. A player with a broad range tends to have extreme opponents, while someone with a narrow range has strong post-flop equity understanding.


The two main types of bluffs in poker are pure and semi-bluffs. While pure bluffs are the most common, semi-bluffs come after the turn or flop and are often used in the case of weak hands. While a pure bluff is a risky strategy, a semi-bluff can still be an effective move if used correctly.

Duplicate cards on the board

Duplicate cards on the board in poker refer to playing the same card twice at different tables. Although it’s rarely done in poker, duplicate cards have been used in bridge tournaments for decades. In bridge, players return the duplicated card back into the deck after each hand. They are then passed from table to table. These duplicate cards are not used to create winning hands, and instead are considered dealer’s cards.

In poker, a Royal Flush is the highest possible poker hand. The odds of obtaining a Royal Flush are 1 in 649,740. But, the probability of a player obtaining one is much smaller than a player obtaining a royal flush, which is why it’s so important to know the odds.

Straight flush

A straight flush in poker is a combination of five cards, from ace to king. While suits are not important when ranking poker hands, the value of the straight is of the utmost importance. A straight flush is also the only poker hand to split the pot if all five cards are of the same suit. The following are the different poker hands and their ranks. Let’s examine each one in detail.

Five of a kind

Five of a kind in poker is a winning hand that consists of at least four cards of the same rank. Although it is a strong hand, quads are difficult to make and are rarely found in poker games.
