Poker is a card game in which players place bets on the strength of their cards. Some games require an initial amount of money to be placed into the pot before dealing the cards (these are known as forced bets). Then, each player can choose to raise or fold his or her hand. The player with the highest hand wins.
A royal flush is a five-card poker hand consisting of a pair of jacks, queens, and kings in sequence with one another and all of the same suits. A straight is five cards that are consecutive in rank but not in suit. A three of a kind is three cards of the same rank and two matching cards. Two pair is two pairs of cards with the same rank, plus one unmatched card.

The game is a constant struggle to weigh the odds of winning and losing, and to maximize their profits. Players must also consider their own confidence level, which can be a powerful ally or a huge liability.
