Ultimate Texas Hold'em® is a poker-based casino game in which the player may make one raise at any time during the course of the hand. The earlier the raise is made the higher it may be. Unlike other poker-based games, raises made after the ante still have action, even if the dealer doesn't open. This game was invented by Roger Snow of Shuffle Master. The same base game, with some minor rule changes, is also distributed by Galaxy Gaming under the name Heads Up Hold 'Em. Evolution Gaming, a supplier of live dealer games to Internet casinos, refers to the game as "Extreme Texas Hold 'Em" in some jurisdictions, for legal reasons.
Following are the standard rules as played in the United States. There is a variant played in Auckland, New Zealand, I address following the standard rules.
* While the standard rules let both player and dealer use any five cards to make their best poker hand, in Auckland, New Zeland, both sides must make use of both hole cards and three of the five community cards. An analysis of the game under this rule can be found in my page on Ultimate Texas Hold 'Em -- Auckland Variant.
