Poker Set Definition
The easiest way to think of a set in poker is as Three-of-a-Kind—three of the same card rank.
Here is where you will find it in poker hand rankings (best to worst):
1. Royal Flush
A Royal Flush is the absolute best hand in poker, consisting of exactly A-K-Q-J-10 of the same suit.
Example: A♠ K♠ Q♠ J♠ 10♠
2. Straight Flush
Five consecutive cards, all of the same suit.
Example: 9♦ 8♦ 7♦ 6♦ 5♦
3. Four-of-a-Kind (Quads)
Four cards of the same rank.
Example: Q♣ Q♦ Q♥ Q♠
4. Full House (Boat)
A boat is a combination of three of a kind plus a pair.
Example: J♠ J♦ J♥ 7♣ 7♠
5. Flush
Five cards of the same suit, not consecutive.
Example: A♣ 10♣ 7♣ 5♣ 2♣
6. Straight
Five consecutive cards of different suits.
Example: 10♦ 9♣ 8♠ 7♥ 6♠
7. Three-of-a-Kind (Trips or Set)
Three cards of the same rank.
Example: 8♠ 8♦ 8♣
8. Two Pair
Two different pairs.
Example: 6♠ 6♣ 4♦ 4♠ 10♥
9. One Pair
Two cards of the same rank.
Example: A♦ A♠ 7♣ 5♥ 3♠
10. High Card
If no one has one pair or better, the player with the highest card wins by default.
Example: A♠ J♦ will beat 9♣ 5♥
Is a Set in Poker a Good Hand?
While a set may seem rather lowly near the bottom of this list, a set is a strong hand in most circumstances. A set can be hard to beat!
Here’s why.
Even though one pair is the second worst-ranked hand, you will only flop a pair 32% of the time—and the better hands are even harder to hit! The truth is you’re usually not going to hit anything.
You and your opponents should usually expect to miss. This fact makes a set pretty powerful.
So, jot this down on your Texas Holdem cheat sheet: when you flop a set, you’re likely to win.
This scenario isn’t always the case. Sometimes, your opponents will have flopped a flush or a straight.
In these instances, a set’s hidden strategic advantage comes into play.
Let’s say you’re holding a pair of 2♠2♣ in your hand.
Flop: K♣2♥Q♦
Eureka! You’ve flopped a set—and your opponents probably haven’t a clue. While flopping a flush on A♥8♥3♥ is a clear possibility given all the hearts on the board, sets are much more concealed.
Therefore, a set’s true value extends far beyond the standard poker set definition. You can beat your opponents, and they won’t see it coming.
When learning how to play poker with a set, its true power lies in its ability to deceive.
Set vs Trips Poker Lingo
We need to address a nuanced question: What is the difference between a “set” and “trips” in poker?
- SET: You were dealt a pocket pair in your hand. Example: 2♠2♣ and the board reads J♥9♦7♠2♥3♦
- TRIPS: Two of the same cards on the board, and you hold the third card in your hand. Example: K♠J♣ and the board reads J♥J♦7♠2♥3♦
A set and trips have the equivalent hand ranking. They are both akin to three-of-a-kind.
Yet, a set refers to the specific sneaky circumstance when you were dealt a pair in your hand, making the three-of-a-kind invisible to your opponents.
| Side note: A common pet peeve in poker is when people confuse a “set” with “trips”! |
Mathematics of a Set in Poker
When it comes to the maths behind hitting sets in poker, you need to know two major poker hand probabilities.
- The likelihood of flopping a set is 12% or 1 in every 7.5 times
- The probability of a flopped set improving to a full house (boat) by the river is 34%
Is it worth the risk?
Since flopping a set is uncommon, you want to make sure you can win a big pot off your opponent(s) to make the gamble worthwhile.
Say you think your opponent may have a bigger pair than you. For example, they re-raised before the flop to signal a hand like pocket aces or pocket kings. You need to check if the maths lines up in your favour.
You should only call a bet with a small pocket pair preflop in hopes of hitting a set if you can win big poker chips value against your opponent.
- Don’t call a $50 bet if your opponent only has $100 in their stack. Mostly, you’re not going to hit that lucky 1 in every 7.5 chance, so don’t risk a lot to win a little.
- Do call a $50 bet if your opponent has $1,000 in their stack! The potential payoff is huge. That 12% miracle can pay you massive dividends. If you crack your opponent’s pocket aces with a sneaky pair of 2♠2♣, their stack could be in your destiny.
It may not be perfect poker GTO poker, but the general protocol is the following:
Don’t try to flop a set unless your opponent has at least 10 times the bet size in their stack.
If they make it $50 preflop, they must have at least $500 more. Otherwise, you should fold!
Set in Poker: Sets → Boats
Keep in mind that the poker set definition is different from the full house definition (‘full house’ and ‘boat’ are used interchangeably).
Full House (Boat) = A combination of three-of-a-kind plus a pair.
This fact means that any set can improve to a full house!
Even if your opponent outdrew you on the flop or turn by hitting a straight or a flush, you can still beat them if your set upgrades to a boat.
Sets are an already powerful hand with the ability to improve.
Set in Poker: Conclusion
A set in poker may not seem like a high-ranked hand, but it’s one of the most profitable holdings you can have.
Sets are hidden, deceptive, and can win huge pots against unsuspecting opponents.
The key is playing them strategically—
- Only chase them when the maths makes sense and capitalise when you hit.
- Since a set can turn into a full house, its strength is even greater than at first glance.
Now that you understand what a set is and how to play it, you’re better equipped to take advantage of this sneaky, powerful hand!
