Here's the tempting offer from Hong Kong millionaire Henry Fok: He will pay half a million dollars to the first non-Chinese player to win a major tournament of Chinese chess.

Fok, a successful businessman and avid player of Chinese chess who wants to promote the game, made the offer early last year, but no one has been able to claim the prize.

Scott Yen of Alhambra hopes to change that.

Yen, 38, an expert at Chinese chess, wants to discover and train the challenger. He hopes an introductory tournament next month in Los Angeles will attract some budding talents. He has also made plans to hold Chinese chess workshops at the Chinese Cultural Center in Alhambra on Monday and Thursday nights.

Chinese chess is similar to Western chess, but some of the pieces move differently, making them weaker or more powerful. There are only a handful of non-Chinese players worldwide who compete in Chinese chess, and none has won a tournament.

"I haven't met any (non-Chinese) who is near my own standard, and I'm only an amateur player," said L. S. Leung, president of the Hong Kong Chinese Chess Assn.

Some players of Western chess, such as Duarte resident Timothy Thompson, have tried Chinese chess but say it is not easy finding playing partners and information about the game.

"I'm looking for a book on this game, but I've never seen one," said Thompson, 39, who is on the board of the Southern California Chess Federation. Thompson, a top player in Western chess clubs in Arcadia and Pasadena, was introduced to Chinese chess in 1971 but has played the game only half a dozen times.

While Chinese chess is still a novelty in Western chess circles, the game is played by more than 520 million people worldwide, Yen said.

Chinese and Western chess are both played with 16 pieces per side, but in Chinese chess there is no queen. The rook, knight, king and pawns move in much the same way as their counterparts in Western chess, but pieces such as the cannon, guard and adviser have no equivalents in Western chess.

To be eligible for the $500,000 prize, the challenger must not be an ethnic Chinese, Yen said. Americans of Chinese ancestry would not qualify. The tournament the challenger must win also has to be of a certain caliber, and Hu Ronghua, the Bobby Fischer of Chinese chess, must be a competitor.

Hu first captured the world championship in 1960 at the age of 15 and held the title for an unprecedented 13 years. Only three or four players have ever been able to win the title twice, Leung said.
