In hold'em, players receive two downcards as their personal hand (holecards), after which there is a round of betting.
Three boardcards are turned simultaneously (called the "flop") and another round of betting occurs.
The next two boardcards are turned one at a time, with a round of betting after each card.
The boardcards are community cards, and a player may use any five-card combination from among the board and personal cards.
A player may even use all of the boardcards and no personal cards to form a hand (play the board). The usual structure is to use two blinds, but it is possible to play the game with one blind, multiple blinds, an ante, or combination of blinds plus an ante. See the previous chapter, "Button and Blind Use," for rules on that subject.
Omaha is similar to hold'em in using a three-card flop on the board, a fourth boardcard, and then a fifth boardcard.
Each player is dealt four holecards (instead of two) at the start.
