I like this old chinese game. Maybe because of mind training or maybe becuse it's unusual. I just like it.
This program lets you play chinese chess (xiangqi) with computer on different levels of mastership. You can start playing on very easy level and finish up with master level. Levels are supported by installing plugins.

Just try it. Here is a website of the author of the program, here is a download page. Again, if you want different levels - download plugins.
