Betfair has a new game where you bet on the winning poker hand out of four (texas hold'em)
you can make quite a bit of money on it too by using back/lay arbitrage and the flop and turn hands. Although i got screwed over by a few hands so it requires a bit a poker knowledge & common sense (luckily i just lost my winnings)
