betting structures Texas Hold'em is commonly played both as a "cash" or "ring" game and as a tournament game. Strategy for these different forms can vary. Cash games Before the advent of poker tournaments, all poker games were played with real money where players bet actual currency (or chips that represented currency). Games that feature wagering actual money on individual hands are still very common and are referred to as "cash games" or "ring games". The no-limit and fixed-limit cash-game versions of hold 'em are strategically very different. Doyle Brunson claims that "the games are so different that there are not many players who rank with the best in both types of hold 'em. Many no-limit players have difficulty gearing down for limit, while limit players often lack the courage and 'feel' necessary to excel at no-limit." Because the size of bets is restricted in limit games, the ability to bluff is somewhat curtailed. Because one is not (usually) risking all of one's chips in limit poker, players are sometimes advised to take more chances. Lower-stakes games also exhibit different properties than higher-stakes games. Small-stakes games often involve more players in each hand and can vary from extremely passive (little raising and betting) to extremely aggressive (many raises). This difference of small-stakes games has prompted several books dedicated to only those games. Tournaments Texas hold 'em is often associated with poker tournaments largely because it is played as the main event in many of the famous tournaments, including the World Series of Poker's Main Event, and is the most common tournament overall. Traditionally, a poker tournament is played with chips that represent a player's stake in the tournament. Standard play allows all entrants to "buy-in" for a fixed amount and all players begin with an equal value of chips. Play proceeds until one player has accumulated all the chips in play or a deal is made among the remaining players to "chop" the remaining prize pool. The money pool is redistributed to the players in relation to the place they finished in the tournament. Only a small percentage of the players receive any money, with the majority receiving nothing. "The percentages are not standardized, but common rules of thumb call for one table" (usually nine players) "to get paid for each 100 entrants," according to poker author Andrew Glazer, in his book, The Complete Idiot's Guide to Poker.
