When I was in high school, my AP Chem class only had a handful of people in it. The chemistry teacher was a pretty awesome laid-back guy, and so in the month of school left after the AP test but before the end of the school year, we pretty much used all our class time to play pinochle.

After a few weeks of playing with the same partner, you can pretty much know what they have in their hand just by the way they play.
