Blocker
A card in your hand that reduces the combinations of strong hands an opponent can hold.
In depth
A blocker is a card in your hand that decreases the number of possible strong hand combinations an opponent can hold. By holding key cards, such as an ace on a flush-draw board, you reduce the likelihood of opponents having premium hands, influencing range-based decisions in gameplay. This concept helps assess an opponent’s potential holdings without relying solely on hand strength.
