Heat ( blackjack)


The pressure a casino puts on a winning player, typically someone who is suspected of being a card counter. It can range from very mild forms, such as a pit boss intently watching a player, unnecessary comments to more overt forms, such as a pit boss counting down the cards in the discard tray, particularly after a player has raised his bet, accusations of counting cards, intent scrutiny of your game by the pit bosses or other casino personnel.
Most counters consider heat to be a warning sign that the casino suspects they are counting.

Heat (roulette)

to be winning too frequently or in big amounts.
