meaning of flush draw

[Roman]

When you stand a possibility of making a flush after the flip, you are considered to be on a flush draw (or turn). A "four-flush" is when a player has four cards of the same kind.
Your flush will be finished with one more. On the other hand, you still need two more cards of the same suit on the final two cards if you merely have three cards of the same suit. A "backdoor" flush drawing is the term used to describe this long shot.

 

[Dallax]

A flush draw is a poker hand that is one card away from being a flush. A flush is a hand that consists of five cards of the same suit. For example, if you have the 5, 6, 7, and 8 of hearts, you have a flush draw because you need the 9 of hearts to complete the flush. Flush draws are generally considered to be good hands, as they have a high chance of improving to a strong hand. The probability of hitting a flush draw on the turn and river is 34.97% if there are two more cards to come, and 19.56% if there is only one more card to come
