In poker, the dealer discards the top card of the deck face down before dealing the community cards, such as the flop, turn, or river. This is done to prevent any players from gaining an unfair advantage by identifying the top card of the deck. The burn card is never revealed to the players, and its use helps maintain the integrity of the game.
Burn Card Example
For example, in a Texas Hold’em game, before dealing the flop (the first three community cards), the dealer burns one card by discarding it face down and then deals the flop. This process is repeated before the turn and river cards are dealt.
