What role do community cards play in Texas Hold'em, and how do they impact the overall strategy of the game?

Community cards are shared cards in Texas Hold'em that are placed face-up on the table. Players use these cards, along with their own hole cards, to make the best possible hand. The community cards impact the overall strategy of the game by providing opportunities for players to create stronger hands, as well as influencing betting decisions based on the potential combinations that can be formed with the community cards. Players must consider the community cards when determining their own hand strength and deciding on their betting actions.
