First episode airs on May 3 2008. It stars Mizobata Junpei from Hanazakari no Kimitachi e and Naka Riisa from Binbo Danshi.Sugata Kentaro is a former professional player of a Japanese chess-like board game known as shogi. (The manga's title comes from the 81 squares on a shogi board.) After leaving the pro circuit, Sugata enters the world of "Shinkenshi" ("true sword-masters"), or players who gamble on shogi and other board games like go and mah-jong. He meets his match in Nakashizu Soyo, a female Shinkenshi who happens to be a part-time maid in Akihabara. -Anime News Network
This is based on a manga I have never heard of but it's kind of interesting. Yay for Mizobata Junpei being in this drama.
