What is a freeroll in poker and how does it impact a player's strategy during a game?

A freeroll in Poker is a situation where a player has the opportunity to win a pot without risking any additional chips. This can happen when a player has a hand that can win the current pot and also has the potential to improve to an even stronger hand on future cards. Freerolls can impact a player's strategy by allowing them to play more aggressively and take risks, knowing that they have a chance to win without investing more chips. Players may also use freerolls to bluff or put pressure on their opponents, as they have the potential to win the pot without having the best hand.
