Set
A set is three of a kind made with a pocket pair plus one matching card on the board. It is stronger and better disguised than trips.
A set is three of a kind made by holding a pocket pair and having one card of the same rank appear on the board. For example, you hold 7♥ 7♣ and the flop is K♦ 7♠ 2♣. Sets are highly valued because they are strong and well hidden: the board shows only a single seven, so your opponents have little reason to suspect three of a kind.
Set versus trips
Both are three of a kind, and they rank the same in the hand rankings. The difference is how they are made:
- Set: pocket pair plus one board card. Hidden and hard for opponents to read.
- Trips: one hole card plus a pair on the board. The paired board warns everyone, and the kicker often matters.
Key numbers
- With any pocket pair, you flop a set or better about 11.8% of the time, close to 1 in 8.5.
- If you miss the flop, you hit a set on the turn 2 times out of 47 (about 4.3%).
- Once you have a set on the flop, you improve to a full house or better by the river about 33% of the time.
Example hand
You call a raise from the big blind with 7♥ 7♣. The flop is K♦ 7♠ 2♣ and the preflop raiser holds A♠ K♥, top pair with the best kicker. You are a heavy favourite. Checking to the raiser is reasonable here, because they are likely to make a continuation bet, and a check-raise can then build the pot quickly. On a dry board like this, there are very few cards that can hurt you.
Now compare a flop of 9♥ 8♥ 7♠. You still have a set, but straights and flush draws are everywhere. Here you generally want to bet or raise right away, so drawing hands pay to try to catch up instead of seeing free cards.
Playing sets well
- Build the pot. Most of a set's profit comes from big pots against top pair or an overpair. Don't slowplay so much that you never get paid.
- Top, middle and bottom set. Top set (the highest board card) is the strongest; bottom set can lose to a higher set, a situation called set over set. It is rare, but it happens.
- Watch the texture. On boards with three to a flush or four to a straight, even a set can become a bluff-catcher.
- Set mining needs implied odds. Calling raises with small pairs hoping to flop a set only pays off when stacks are deep enough to win much more than you invested.
