The first step to being good at no limit Texas Hold 'Em is understanding the game of Hold 'Em and the best way to get started on that road is to understand the basics of how the game works. At the start of the game, each player is dealt two cards (referred to as the hole cards) face down. These are cards that only they can use in the game. After a round of betting, the flop is then dealt (three community cards face up in the centre of the table that every player can use). After the flop has been dealt there is another round of betting before the turn is dealt (one more community card next to the flop). Another round of betting takes place at which point the final community card, the river card, is dealt. One more round of betting occurs at the end of which the remaining players in the hand show their hand and the best five card poker hand formed from a player's two cards and the five community cards wins the hand and takes the pot.
This is true for every poker game of Hold 'Em, regardless of what the betting rules are. The betting rules in no limit Texas Hold 'Em however are what create the emotional roller coaster that causes it to be referred to as the Cadillac of poker games.

The seconds or even minutes that tick by from the point that you do that move to when the opponent decides whether to call or fold are some of the most emotional moments you are likely to have in your life; the bigger the pot, the higher the emotions.
