I can't find any sign of this on Yahoo's Website, but a press release from the Computer Games Development Conference Europe speaks of “Yahoo! Poker, a multiplayer cross platform title, which lets mobile phone gamers play against those on their PCs.” Man, there's gotta' be some way to cash in on the poker craze...

You know, you don't make money chasing gold, you make money selling to people chasing gold (Levi's, Wells Fargo). Maybe a Texas Hold 'Em trainer: instead of actually playing out the hands, test the ability to evaluate the odds based on position and pot odds. That's easy to calculate (for a computer) until you get to the challenge of evaluating another player's betting sequence, which is intractable to a simple algorithm.
