Crazyhouse is one of my favorite chess variants. Zillions plays it not
especially strong, so you need to download Sunsetter or Sjeng, which play
really good. I even created a WinBoard adapter for Zillions (see
http://www.geocities.com/andreas_kaufmann2000/winboard_adapter.htm) to
have a convinient way to play against these engines.
