Concealed Pair
A concealed pair is a pair in which both cards are face down.
The simple explanation
In games like stud, some cards are face up and others face down. A concealed pair has both of the pair cards face down, so opponents cannot see it.
A closer look
A hidden pair is stronger as a surprise than a visible one. Opponents have to guess whether a bet comes from a pair or from something else. In seven-card stud, a pair in the hole is also called a buried pair, and players use it to disguise strong hands. Players watch the upcards of opponents to guess whether a pair is concealed. If an opponent shows no pair but bets strongly, he may have one hidden.
A practical example
A stud player has two face-down aces and a king showing. His pair is concealed.
Full explanation
A concealed pair is a pair in which both cards are face down.
A concealed pair is a pair in which both cards are in the hole. It is sometimes called a buried pair in stud games.
Because the cards are not visible, opponents cannot see the pair. They have to guess from your betting, which gives you room to disguise a strong hand.
In contrast, an exposed pair has at least one card face up. Opponents can see the pair or part of it and may play around it.
The term applies to stud games, where some cards are dealt face down and some face up.
