Check

Checking means declining to bet while staying in the hand, passing the action to the next player without committing chips. A player may only check when no one has bet before them in the current round; if there is a live bet, the choices are to Call, raise, or fold. If every remaining player checks, the betting round ends and the next community card is dealt, or, on the river, the hand proceeds to showdown. A check is a passive action that neither extracts value nor surrenders the hand. Worked example: you hold a modest pair on the Board in Texas Hold'em and are first to act after the flop with no bet in front of you. Rather than betting and risking a raise from a stronger hand, you check to control the size of the pot and see the turn cheaply. If your opponent also checks, you reach the turn having invested nothing further; if they bet, you can fold at minimal cost or continue with information you would not have had if you had bet first. Checking matters because pot control and deception both run through it. A check can disguise a strong hand to set up a Check-Raise, or keep the pot small with a marginal holding. The common mistake is checking too automatically out of weakness, which lets aggressive opponents bet freely and seize the initiative — sometimes called being run over. Skilled players balance their checking range so opponents cannot assume a check always means weakness. Used deliberately, the check is a tool; used reflexively, it forfeits the betting lead and the value that comes with it.
