Antes up, a common poker term, means to put money or chips in the pot before starting a game. However, there are several antonyms for this term which indicate the opposite action. For instance, the phrase 'folds' means to withdraw from a game entirely by choosing not to put anything in the pot. Another possibility is 'checks', which means to place nothing in the pot but still remain in the game. 'Calls' is another option, which is when a player matches the amount of a previous bet. Finally, 'raises' signifies an act of increasing the initial amount placed in the pot. All of these terms relate to the different possible actions a poker player can take when it is their turn to place a bet.
