Placing a bet equal to the current highest bet is called calling. Raise means placing a bet equal the highest bet, plus more to get the highest bet. When the player places a bet which is higher than the highest bet it is called raising. Checking allows the player to stay in the game without calling or raising, however, this may only be done if no one has placed a bet before you. If you think that you will hardly win you can fold. In this case you lose your bet and any chance of winning. Online Jackpot Poker Fold.
