Minnesota is now one of several states where legislators are looking to clarify laws dealing with card games at a time when poker is becoming an all-out craze.

"These are just people who have been watching poker on TV and they want to come out and play and be like the people on TV," said Bischoff, whose tournaments are up and running again. "It's not about spending money and winning money. It's just about the competition and seeing who can be the best."

The game at the center of the poker mania is Texas Hold 'em, in which players are dealt two cards each and can use five community cards flipped over in the middle of the table to make the best hand. Players can risk everything on a single turn of a card.

As the popularity of the game has grown, so have problems for gambling regulators.

In Iowa, a couple of American Legion posts heeded warnings and halted their regular tournaments rather than jeopardize their charitable gaming licenses. A similar concern led a firehouse outside of Pittsburgh to call off its games.

Police in Wyoming started breaking up Texas Hold 'em tournaments in bars, and the state's attorney general advised that the events were probably illegal. In Texas itself — where the game thrived in smoky back rooms before becoming a smash hit on cable TV — prosecutors are questioning whether bars are improperly profiting from tournaments.

"The popularity of the poker shows has created a whole new beast for us as far as regulations," said David Werning of Iowa's Department of Inspections and Appeals.

Hawai'i state law allows "social" gambling, provided all parties compete on equal terms, the "house" does not profit, it is not done at a business establishment or in public, all players are 18 or older, and there is no bookmaking.

Minnesota law allows card tournaments at bars and businesses as long as the hosts do not directly profit from the play and players do not gamble with real money. Bischoff said he complied with those rules by charging no entry fees and limiting awards to hats and T-shirts.

His situation drew the attention of state Sen. Dave Kleis, who this month introduced legislation that would define Texas Hold 'em as a "social skill game" and lump it with card games like cribbage and rummy — games in which players are allowed to win money in Minnesota.

Kleis' bill would explicitly permit poker tournaments as long as the prizes do not exceed $200.

"It's no different than cribbage, 500, euchre or bridge. Those are played all over the state, whether it be in nursing homes, restaurants or bars," Kleis said. "Why don't you raid the nursing home for playing cribbage and bridge?"

Kurt McPhail of the Amateur Poker League, a Kansas City-based business that runs more than 400 events a week across nine states, complained that regulators are unfairly clamping down on poker tournaments.
