Practical Poker Math

Odds With 2 Cards to Come
With 2 cards to come there are 4 possibilities:
1. You will hit none of your outs on either card
2. You will hit one of your outs on the Turn
3. You will hit one of your outs on the River
4. You will hit one of your outs on the Turn and
another on the River.
When calculating the odds with 2 cards to come, one important
number is the total number of possible 2-card combinations
that can be made from the remaining unseen 45 cards
— Comb(45, 2):
(45 * 44) = 990
(1 * 2)
To find the WILLs, add the number of possible 2-card combinations
that will contain 1 and only 1 of the available outs
to the number of 2-card combinations that will contain 2
out cards.
Low Draw >>> Low with 2 Cards to Come
With a Low draw, 16 of the unseen 45 cards will make a Low.
There are also 6 cards among the 45 that will counterfeit one
of the low cards in the hole. Of the 45 unseen cards, there are
16 that will make the Low and 23 that can combine with one
of these 16 to make the Low without counterfeiting one of
the low cards in the hole.
