A royal flush is a very rare and powerful hand, consisting of the highest ranking cards in each suit.

A player’s decision to call a bet is based on the realized value of his or her cards after the flop, turn and river have been revealed. This value is determined by the probabilities of making a particular type of poker hand and the odds that the opponent has of making that hand.
