The poker term brick is used to describe a community card that isn’t likely to influence anyone’s hand in any significant manner. This term is the synonym of the poker expression ‘blank.’
For example, on a board of 6h7hKs, a 2d on the turn would be considered a complete brick. This card doesn’t complete any of the flush or straight draws from the flop, and it is unlikely to improve anyone’s hand.
A brick is the complete opposite of an action card. While action cards complete draws and motivate players to start betting and raising, bricks usually don’t change the action too much. If someone was betting big on the flop, they’re likely to continue when a brick card hits the turn.
When picking your bluffing spots, bricks should be avoided. If you suddenly start representing a big hand on a card that simply isn’t likely to have helped you, your opponents will sniff it out.
