Smartphone connected chessboards are nothing new. The Square Off, Chessnut Air, and Millennium Chess computers are all capable of connecting to your iPhone for online play. The iChessOne is also worth a look. It is a wooden foldable electronic chessboard that lets you play online chess on a real board. It has LEDs to show you where to move the pieces.
The board insert fits all the 32 pieces plus two extra queens. Its engine has 8 difficulty levels for you to choose from. Your games are recorded, so you can use their PGN to further analyze your games. What’s neat about this board is its support for ultra-fast games. It uses magnetic sensors and RFID to register your moves fast.[where to get it]
