DGT Wenge Electronic Chessboard Serial Port Version. Royal Pieces

This electronic chess board is great for anybody from professional to just a beginner, as long as you have some money handy. These things connect up to your computer through serial port (and USB and bluetooth are also available) and your PC or mac turns into a virtual chess buddy for training, or aiming up your skills for some serious competition. The board is equipped with sensors that allows your computer to track each piece at every moment and play against you. (Which is pretty hard. I can't even beat a computer on easy mode)
