People start playing poker every day every where over the world. Well, at least, where poker is considered legal. The bad thing with poker is that it can be a bit complicated for beginners at first when they don’t have the essential information on how to start a players career. This article focuses essentially on online poker or poker on a computer, and specifically on the mac 
First thing you’ll need is an account on FullTilt or Pokerstars (links are at the top of this page).
Secondly, i must say, the most popular variant is the community poker holdem. It’s called community because some dealed cards are seen by all the players, placed in the middle of the table.
Betting structures
Hold ‘em is normally played using small and big blind bets – forced bets by two players. Antes (forced contributions by all players) may be used in addition to blinds, particularly in later stages of tournament play. A dealer button is used to represent the player in the dealer position; the dealer button rotates clockwise after each hand, changing the position of the dealer and blinds. The small blind is posted by the player to the left of the dealer and is usually equal to half of the big blind. The big blind, posted by the player to the left of the small blind, is equal to the minimum bet. In tournament poker, the blind/ante structure periodically increases as the tournament progresses. (In some cases, the small blind is some other fraction of a small bet, e.g. $10 is a common small blind when the big blind is $15, and still other tables may use two equal blinds. The double-blind structure described above is a commonly used and more recent adoption.)
When only two players remain, special ‘head-to-head’ or ‘heads up’ rules are enforced and the blinds are posted differently. In this case, the person with the dealer button posts the small blind, while his/her opponent places the big blind. The dealer acts first before the flop. After the flop, the dealer acts last and continues to do so for the remainder of the hand.
The three most common variations of hold ‘em are limit hold ‘em, no-limit hold ‘em and pot-limit hold ‘em. Limit hold ‘em has historically been the most popular form of hold ‘em found in casino live action games in the United States.[19] In limit hold ‘em, bets and raises during the first two rounds of betting (pre-flop and flop) must be equal to the big blind; this amount is called the small bet. In the next two rounds of betting (turn and river), bets and raises must be equal to twice the big blind; this amount is called the big bet. No-limit hold ‘em is the form most commonly found in televised tournament poker and is the game played in the main event of the World Series of Poker. In no-limit hold ‘em, players may bet or raise any amount over the minimum raise up to all of the chips the player has at the table (called an all-in bet). The minimum raise is equal to the big blind. If someone wishes to re-raise, they must raise at least the amount of the previous raise. For example, if the big blind is $2 and there is a raise of $6 to a total of $8, a re-raise must be at least $6 more for a total of $14. If a raise or re-raise is all-in and does not equal the size of the previous raise, the initial raiser can not re-raise again. This only matters of course if there was a call before the re-raise. In pot-limit hold ‘em, the maximum raise is the current size of the pot (including the amount needed to call).
Most casinos that offer hold ‘em also allow the player to the left of the big blind to post an optional live straddle, usually double the amount of the big blind, which then acts as the big blind. No-limit games may also allow multiple re-straddles, in any amount that would be a legal raise.
Play of the hand
Each player is dealt two private cards in hold ‘em. They are dealt first.
Play begins with each player being dealt two cards face down, with the player in the small blind receiving the first card and the player in the button seat receiving the last card dealt. (As in most poker games, the deck is a standard 52-card deck containing no jokers.) These cards are the player’s hole or pocket cards. These are the only cards each player will receive individually, and they will only (possibly) be revealed at the showdown, making Texas hold ‘em a closed poker game.
The hand begins with a “pre-flop” betting round, beginning with the player to the left of the big blind (or the player to the left of the dealer, if no blinds are used) and continuing clockwise. A round of betting continues until every player has folded, put in all of their chips, or matched the amount put in by all other active players. See betting for a detailed account. Note that the blinds are considered “live” in the pre-flop betting round, meaning that they contribute to the amount that the blind player must contribute, and that, if all players call around to the player in the big blind position, that player may either check or raise.
After the pre-flop betting round, assuming there remain at least two players taking part in the hand, the dealer deals a flop, three face-up community cards. The flop is followed by a second betting round. This and all subsequent betting rounds begin with the player to the dealer’s left and continue clockwise.
After the flop betting round ends, a single community card (called the turn or fourth street) is dealt, followed by a third betting round. A final single community card (called the river or fifth street) is then dealt, followed by a fourth betting round and the showdown, if necessary.
In all casinos, the dealer will burn a card before the flop, turn, and river. Because of this burn, players who are betting cannot see the back of the next community card to come. This is done for historical/traditional reasons, to avoid any possibility of a player knowing in advance the next card to be dealt due to it being marked.[9]
The showdown
If a player bets and all other players fold, then the remaining player is awarded the pot and is not required to show his hole cards. If two or more players remain after the final betting round, a showdown occurs. On the showdown, each player plays the best poker hand they can make from the seven cards comprising his two hole cards and the five community cards. A player may use both of his own two hole cards, only one, or none at all, to form his final five-card hand. If the five community cards form the player’s best hand, then the player is said to be playing the board and can only hope to split the pot, since each other player can also use the same five cards to construct the same hand.[9]
If the best hand is shared by more than one player, then the pot is split equally among them, with any extra chips going to the first players after the button in clockwise order. It is common for players to have closely-valued, but not identically ranked hands. Nevertheless, one must be careful in determining the best hand; if the hand involves fewer than five cards, (such as two pair or three of a kind), then kickers are used to settle ties (see the second example below). Note that the card’s numerical rank is of sole importance; suit values are irrelevant in Hold’em. The last player to bet is the first player to show there hand.
Another thing to get down is the glossary terms, they are very specific to poker and are very important if you want to understand a standard article or conversation. Here’s a link you should definitely bookmark from Wikipedia: Glossary of poker terms.
