The Odds of Making a Full House in Poker

Odds of Making a Full House on the Later Streets

There are generally two main types of Full House draw postflop -

1) We have a Two Pair and are drawing for one of our Pairs to make trips.

2) We have Three of a Kind and are hoping that we make a Pair.

Scenario 1 is the easiest since we know exactly which cards we are waiting to Pair.

Example 1

Flop: KT7
Our Hand: KT

We already have two pair and can either catch a King or a Ten to make a Full House. There are two Tens and two Kings left in the deck, giving us a total of four possible outs.

Odds of hitting on the turn = 4/47 = 0.0851 or roughly 8.5%

Odds of hitting on the river = 4/46 = 0.087 or roughly 8.7%

Odds of hitting on the turn or river (we’ll calculate Odds of not hitting then deduct from 100).

Odds of not hitting on the turn = 43/47

Odds of not hitting on the river = 42/46

Odds of not hitting on the turn or river = 43/47 * 42/46 = 0.8353 or roughly 83.5%

Odds of hitting is, therefore (100 – 83.5) roughly 16.5%

Scenario 2 is a little bit tougher since we can also make a Full House if the board pairs.

Example 2

Flop KT7
Our Hand: TT

We already have Three of a Kind here and simply need any other card to pair. Either the King or Seven could pair for a total of 6 outs. It’s also worth considering that we can catch the case Ten (one out) to make Quads.

Assuming the turn bricks, it still puts another card out there that can pair by the river. In other words, unlike the previous example, we are guaranteed to pick up additional outs on the turn if we don’t hit.

Odds of hitting on the turn (including Quads) = 7/47 = 0.1489 or roughly 15%

Odds of hitting on the river (including Quads) = 10/46 = 0.2174 or roughly 21.7%

We are noticeably more likely to hit our Full House going from turn to river.

Odds of hitting on the turn or river (we’ll calculate Odds of not hitting then deduct from 100).

Odds of not hitting on the turn (including Quads) = 40/47

Odds of not hitting on the river (including Quads) = 36/46

Odds of not hitting on the turn or river = 40/47 * 36/46 = 0.6660 or roughly 66.6%

Odds of hitting by the river are hence (100-66.6) roughly 33.4%

Implied Odds Analysis of a Full House

Like most other strong hands, the value of the implied odds depends much on the relative strength of the holding. There are strong Full Houses and weak Full Houses.

Keep in mind the following -

Overfull/Underfull – The terms “overfull” and “underfull” are used to describe nut and non-nut Full Houses, respectively. For example, on an 8-8-7 board, 87 is the overfull while 77 is the underfull.

In most cases, it’s just a cooler if these hands run into each other, but technically the two-card overfull carries better-implied odds than the two-card underfull.

One-Card/Two-Card – The issue of overfull/underfull becomes even more pronounced when we are dealing with one-card Full Houses (i.e. using only one of our hole cards to create the hand).

On a TT77x any Tx is the overfull while any 7x is the underfull. Seeing as it’s simply much more common that any player would have a Full House on a double-paired texture, the one-card underfull needs to be treated with caution.

The one-card underfull is actually more likely to generate reverse implied odds than implied odds due to the high possibility it is dominated if Villain wants to get the stacks in.

Basic Strategy Advice

Full Houses are ultra-strong hands in Hold’em and should nearly always be stacked off for 100bb stacks. The only exception is really the one-card underfull. This is still a relatively strong hand, but we’ll likely try and avoid getting all of the stacks in when facing aggression.
