What is Out's?

 Outs is any card that would make your hand better.

Outs - Which cards can help me?

Your outs are all cards that could show up in the community and help your hand. Some out cards are more helpful than others; when you play a draw you are looking for the outs that give you the best possible hand. We will talk more about this later.

EXAMPLE A

Right now your hand looks pretty worthless and has no chance of winning a showdown. If however, an ace or a six land on the board, you would have a straight: a strong made hand.

At this moment your outs are aces and sixes. Now you have to ask yourself, how many outs does that make? Since there are four aces and four sixes in the deck of cards,  there are a total of 8 cards that could be dealt on the turn or the river, to give you a straight.

EXAMPLE B

Now you are in an even better situation. You don't only have the chance to make a straight with any ace or six, you would also have a flush if another club were dealt.

You can now count the remaining club cards as outs. Since there are 13 clubs and 4 have already been dealt, there are 9 clubs remaining in the deck.

As you've already counted the ace and six of clubs, you have 6 more out cards (3 aces and 3 sixes) for your straight draw. The 9 flush outs and the 6 straight outs give you a total of 15 outs:

FURTHER EXAMPLES

• Flushdraw - 9 Outs
  There are 13 cards of each suit in the deck and 4 have been dealt. This leaves 9 outs to complete a flush.
  
  
• OESD (Open Ended Straight Draw) - 8 Outs
  Any 4 or 9 would complete an OESD and give you a straight. OESDs always have 8 outs.
  
  
• Overcards - 6 Outs
  There are 3 Aces and 3 queens remaining in the deck. Any of those would give you top pair. Overcards give you 6 outs on a draw for top pair.
  
  
• A three of a kind or two pair draw - 5 Outs
  There are 2 eights left in the deck that would give you a three of a kind. One of the three remaining kings would give you a two pair. This gives you a total of 5 outs to better your small pair.
  
  
• Gutshot - 4 Outs
  A gutshot draw is the weakest straight draw. One card is missing from the middle of the sequence, which means you would need a 'gutshot' to complete the sequence. There are four outs for a gutshot draw, four twos in this case.
