What is an out?
In this example, you know 6 cards before the
River card is dealt, 2 cards in your hand and 4 on the
board. Since there are 52 cards in a deck, this means you do
not know the other 46 cards. If you did have 9 outs that
means the other 37 (46-9 = 37) cards in the deck would be
non-outs.
The concept of the number of unknown cards
may be confusing since there are actually less than 46 cards
left in the dealer’s hand after the Turn. If he has dealt in
10 players, it means he has dealt 20 cards to the players.
With 4 cards on the board after the Turn, this would mean
the dealer would only have 28 cards left in the deck in his
hand (actually 26 since he has burned two cards, one before
the Flop and one before the Turn). However since we do not
know what the other players’ holdings are, it is usually
correct to assume 46 unknown cards after the Turn. For any
particular card, there is a chance it was dealt to another
player or still left in the deck. Since we do not know which
cards were dealt to the players or are still in the deck, we
cannot make any assumptions about what is left in the deck.
Sometimes we can be quite sure of an opponent’s two hole
cards based on the play of the hand thus far, in these
cases, we can be sure there are only 44 unknown cards. But
these are rare cases, it is usually correct to assume 47
unknown cards after the Flop and 46 unknown cards after the
Turn.
Counting Outs
The process of counting outs is a
combination of art and science. If we knew exactly what our
opponent’s cards are, then it would be a science, as we
would be able to calculate our outs and non-outs. But poker
is a game of imperfect information. It is an unusual
circumstance when we know the exact two cards our opponent
holds but we can often have a good idea of what the other
players may hold based on their play so far. A player who
has the ability to read the hands of his opponents with
precision will be able to pinpoint his opponents’ cards with
a greater degree of accuracy than those players who cannot
read hands well. But even for the great hand readers, there
is usually a level of uncertainty.
