What Is a Backdoor Draw in Poker?

A backdoor draw in poker is a hand that needs two specific cards, one on the turn and one on the river, to become strong. Unlike a regular draw that needs only one card, a backdoor draw requires both remaining community cards to go your way, which is why it is also called a runner-runner draw.

Backdoor Draw in Poker: Key Points

  • You need both the turn and the river to complete your hand because you’re two cards short after the flop.
  • These hands are often called a runner-runner draw because you need two cards to “run” out in your favor back-to-back.
  • While backdoor draw are hard to hit, they add a little bit of extra value to your hand.

Backdoor Draw vs. Draw

The main difference here is how many cards you still need to complete your hand.

  • A “regular” draw is much stronger because you need one more card. For example, with four cards to a straight, you have roughly an 18% chance to hit it on the next card.
  • A backdoor draw is much weaker because you’re starting with only three cards toward your goal. You must hit the right card on the turn just to have a chance on the river.

If you don’t hit the right card on the turn, your draw is dead. You can’t catch up anymore. This is why a regular draw is usually worth betting on, while a backdoor draw is more like a “bonus” feature of your hand.

Types of Backdoor Draws

There are two types of backdoor draws in poker.

Backdoor Flush Draw

The backdoor flush draw happens when you have two cards of the same suit in your hand, and only one card of that suit shows up on the flop. Since a flush requires five cards, and you only have three, you need both the turn and the river to be of the same suit to complete it.

This type of backdoor draw is effective because it’s well disguised. Since the flop doesn’t show an obvious flush threat, opponents often feel safe and don’t expect the flush to come together later.

Backdoor Straight Draw

The backdoor straight draw occurs when you need two very specific cards on the turn and river to complete a straight. For example, if you hold a 7 and an 8 and the flop comes K-2-9, you technically have the beginnings of a straight, but you’re far from completing it.

If the turn brings a 6 and the river brings a 5, you end up with a straight—but only because both cards arrived in the exact order you needed. This makes backdoor straights hard to spot and easy for opponents to underestimate until the hand is over.

Backdoor Draw Odds and Equity

Because you need two specific cards—one on the turn and one on the river—backdoor draws provide very little equity. A backdoor flush draw has roughly a 4% chance to complete from the flop, meaning you’ll only hit it once every 25 hands.

While backdoor flush draw odds are low, they aren’t zero. If you already have a made hand, like a pair, that extra equity can sometimes justify continuing in the hand.

Backdoor straight draws are even weaker, usually offering around 2% to 3% equity, depending on the exact card combinations involved.

Even with such small percentages, experienced players factor backdoor draws into their calculations in both online poker sites and live tournaments, looking for every possible edge.

Common Mistakes with Backdoor Draws

A lot of new players get into trouble because they think a backdoor draw is better than it really is. Here are the four most common mistakes with backdoor draws in poker.

  • Chasing when the bet is too big. You should not pay a large sum to see the next card if all you have is a runner-runner draw. The math just doesn’t work out.
  • Ignoring the cards on the table. Sometimes you might hit your backdoor flush, but the board also pairs up, giving someone else a full house. Always look at the whole picture.
  • Overestimating your backdoor draw equity. Just because you have a 4% chance doesn’t mean you should play the hand like you’re the favorite to win.
  • Forgetting to bluff. Sometimes, a backdoor draw is a good hand to bluff with because if you don’t hit your card on the turn, you can still try to represent a different hand, but this is a more advanced move.

The key is to treat backdoor draws as a small bonus to your existing hand strength, not as a reason to call by themselves.
