Chihayafuru is based on a josei manga by Suetsugu Yuki, who was found to be plagiarising a bunch of art and was forced into hiatus. Chihayafuru is her first work since returning from exile and is about a bunch of childhood friends who are tied together by Karuta: the ancient Japanese game of smacking cards with ancient Japanese poetry away from each other.
Well, that sounds boring. Yeah, it does. You know what else sounds boring? Go, shogi, and baseball, and yet, these games have spawned excellent anime and manga that makes the game interesting and serves as the glue to the real part of the story: relationships!
It is very prettily produced by the folks at Madhouse and is directed by a guy who also directed Cardcaptor Sakura and Nana, so that is a pretty solid record. You can watch it on Crunchyroll as it comes out each week on Tuesdays and it'll be 25 episodes long.
