This one is about a type of chess called Shougi. Kind of similar to Hikaru no Go in the way it is featured. I think you will like this one too if you liked Hikaru no Go.

This one also has a darker side to it, showing some pretty tragic hardships some characters have to go through. Overall I think this is a really good manga, and you guys should give it a try as well. See this page for more details on english scanslations.
