A poker player is drawing if they have a hand that is incomplete and needs further cards to become valuable. The hand itself is called a draw or drawing hand. For example, in seven-card stud, if four of a player's first five cards are all spades, but the hand is otherwise weak, they are drawing to a flush. In contrast, a made hand already has value and does not necessarily need to draw to win. A made starting hand with no help can lose to an inferior starting hand with a favorable draw. If an opponent has a made hand that will beat the player's draw, then the player is drawing dead; even if they make their desired hand, they will lose. Not only draws benefit from additional cards; many made hands can be improved by catching an out — and may have to in order to win.

2Types of draws

I assume you mean a Q or a 7 to complete the straight. You have 8 outs (4 queens, 4 sevens). There are 47 cards unaccounted for (in the deck or in other players' hands) after the flop. So the chance that you will miss your straight on the tu. Obviously, you're always looking to get your money in in poker with good odds. After a pre-flop raise, a bet and likely a raise on the flop, you're getting way more than the required break-even odds on your robust draw. If you're going to win the pot 50% of the time, your break-even odds only have to be 1-1.

Outs[edit]

An unseen card that would improve a drawing hand to a likely winner is an out. Playing a drawing hand has a positive expectation if the probability of catching an out is greater than the pot odds offered by the pot.

The probability ${displaystyle P_{1}}$ of catching an out with one card to come is:

{displaystyle P_{1}={frac {mathrm {outs} }{mathrm {unseen} ,mathrm {cards} }}}

The probability ${displaystyle P_{2}}$ of catching at least one out with two cards to come is:

{displaystyle P_{2}=1-{frac {mathrm {non} ,mathrm {outs} }{mathrm {unseen} ,mathrm {cards} }}times {frac {mathrm {non} ,mathrm {outs} -1}{mathrm {unseen} ,mathrm {cards} -1}}}

{displaystyle mathrm {non} ,mathrm {outs} ={mathrm {unseen} ,mathrm {cards} }-mathrm {outs} }

A dead out is a card that would normally be considered an out for a particular drawing hand, but should be excluded when calculating the probability of catching an out. Outs can be dead for two reasons:

A dead out may work to improve an opponent's hand to a superior hand. For example, if Ted has a spade
