section. As usual, we’ll talk about how to do this exactly, and
then give a shortcut for table play. Again, there is no substitute
for away from the table work to develop a good feel for this at
the table.
Determining your equity against a range is done in four steps.
1. Determine your equity against each hand in the range.
2. Multiply that equity by the number of combinations for
that hand.
3. Add together the results from step two for each hand in
the range.
4. Divide the results from step three by the total
combinations in the hand range.
Let’s work this one out. We’ll start by determining our equity
against each hand in his range.
78: 66%
55: 9%
66: 9%
We’re in great shape against 78, but we’re absolutely crushed by
55 and 66.
Let’s move on to step two and multiply the equity by the number
of combinations for that hand.
78: 0.66 * 16 = 10.56
55: .09 * 3 = 0.27
66: .09 * 3 = 0.27
Moving on to step three, we add together these sums.
