Three of a Kind in Poker: Hand Rank & Best Strategy to Use

What is Three of a Kind in Poker?

In poker hand rankings, a three of a kind has three cards of the same rank plus two unrelated cards (creating a five-card poker combination). For example, 9♠ 9♦ 9♣ K♠ 6♥ is three of a kind, nines.

Three of a kind is a hand that holds up well and dominates the weaker holdings like one pair and two pair. Most players see this hand as a sign they’re in good shape, especially when it’s made early, on the flop. 

However, three of a kind can be vulnerable to stronger hands, such as straights, especially on a wet board. Judging your hand’s relative strength, not just its raw power, is essential in those situations.

The best possible three of a kind is A♠ A♥ A♦ K♠ Q♦, made with the top-ranked aces and the two highest kickers, king and queen. But not all three of a kind hands are made the same! Let’s examine the different types.

The Difference Between Sets, Trips, and Three of a Kind

In poker slang, three of a kind has a few different names, based on how you make the hand. 

Let’s break it down how it would look in a Texas Hold’em game: 

Different Hand Name	Definition	Example
Set	Made using a pocket pair (two matching hole cards) and one card from the board.	You hold 8♠ 8♦. The flop is 8♣ K♠ 3♥.
Trips	Two matching cards are on the board, and one is from your hand.	You hold A♣ 7♦. The board shows A♥ A♠ 10♣.
Three of a Kind	A general term for any hand containing three cards of the same rank.	5♠ 5♦ 5♥ 9♣ 2♦.

How Does Three of a Kind Rank in Poker?

Three of a kind in poker sits towards the middle of the poker hand rankings. It’s stronger than two pair and any single-pair hand, but it still falls behind straights, full houses, and the premium hands above those.

The hand earns respect because it’s rare enough to surprise opponents but common enough to appear relatively regularly. When you make three of a kind, especially a set on the flop, you often have a real chance to build a nice pot.

What is the best three of a kind in poker?
A: A♠ A♥ A♦ K♠ Q♦. Made with three aces and the two top kickers.

What is the worst three of a kind in poker?
A:2♠ 2♦ 2♣ 3♥ 4♦. Has the lowest possible rank of twos and the weakest two kickers.

What Beats Three of a Kind in Poker?

When looking at what beats what hand, three of a kind loses to a straight, flush, full house, four of a kind, straight flush, and royal flush. You can also lose to a more powerful three of a kind, for example, three kings beats three nines. Those stronger hands don’t show up very often, but when the board is connected or has multiple suited cards, the risk increases.

What Does Three of a Kind Beat in Poker?

Three of a kind beats two pair, one pair, and any high-card hand, as well as a lower-ranked three of a kind. This makes it a reasonably strong hand that can win many small to medium pots without further improvement. Of course, upgrading to an even more powerful full house and four of a kind is possible, with a few outs available. 

Three of a Kind vs Three of a Kind – Who Wins?

When two players make three of a kind, the winner holds the higher-ranked trio. For instance, Q♠ Q♦ Q♥ 9♣ J♠ beats J♠ J♦ J♥ 9♣ Q♠ because queens outrank jacks.

If both players share the same trips using the board, the kickers decide the winner. In rare cases where both the trips and kickers are identical, the pot is split evenly.

What is the Probability of Getting Three of a Kind?

Three of a kind in poker turns up often enough to matter, so knowing the poker odds for the hand can give you the edge in the heat of a battle.

Poker Situation	Your Hand (Example)	Board Stage	Board	Chance %	Chance Odds
Flopping three of a kind with unpaired hole cards	7♠ K♦	Flop	K♣ K♥ 2♠	1.35%	1 in 74.1
Flopping three of a kind with a pocket pair	8♣ 8♦	Flop	8♠ J♥ 3♣	11.51%	1 in 8.69
Pocket pair on the flop to three of a kind on the turn	9♥ 9♠	Turn	Q♦ 5♣ 2♠ → 9♦	4.26%	1 in 23.5
Pocket pair on the flop to three of a kind on the turn or river	6♣ 6♦	Turn + River	A♠ 10♥ 4♣ → 5♠ → 6♥	8.42%	1 in 11.9
Pair on the flop to three of a kind on the turn	Q♠ 10♦	Turn	Q♦ 7♥ 3♣ → Q♥	4.26%	1 in 23.5
Pair on the flop to three of a kind on the turn or river	J♥ 9♦	Turn + River	J♠ 8♣ 5♣ → 2♦ → J♦	8.42%	1 in 11.9

It is relatively rare to flop three of a kind in Texas Hold’em, unless you start with a pocket pair. If you have a pocket pair, you should treat it as a potential opportunity because your chance to hit trips by the river is meaningful.
