Have to promote a card game a bit.. it's of Chinese origin, uses poker
combinations and in English it's called The Big Two. You play it with
four people, and it's very good for a drinking game (ie. the loser drinks
the alcohol that the winner pours him). If you like card games, this is
quite easy to learn and you can find instructions from the Internet, for
instance from "http://lynx.dac.neu.edu/n/ncheung/cardgames/choidaidi.html".

I learned it from my Chinese colleagues and they play it very seriously,
often with very high bets.
