What does freeroll mean in poker and how does it impact gameplay and strategy?

In Poker, a freeroll is a situation where a player has the opportunity to win a pot without risking any additional money. This can happen when a player has a hand that can win the pot outright or when they have a chance to improve their hand on future cards. Freerolls can impact gameplay and strategy by giving players more options to play aggressively or passively, depending on their hand strength and the potential for improvement. Players can use freerolls to bluff, extract value from opponents, or make strategic decisions based on the likelihood of winning the pot.
