Sensory chessboard and method for detecting positions of chess pieces on a chessboard and transmitting those positions to a computer or other electronic recording device

A chessboard, comprising:

• a top layer comprising sixty-four (64) squares of alternating color arranged in eight parallel ranks and eight parallel files, wherein the ranks are arranged perpendicularly to the files;
• a bottom layer comprising a circuit board, said circuit board comprising sixty-four (64) radio frequency identification antennas arranged in registration with said sixty-four (64) squares of alternating color in said top layer;
• and,
• an electronic circuit embedded in said circuit board operatively arranged to receive a unique digital code stored in a radio frequency identification tag in each chess piece positioned atop said chessboard and to sense positions and movement of said chess pieces on said sixty-four (64) squares of said top layer, and communicate said positions and movement to a computer,
• wherein said circuit board includes a circuit comprising said sixty four (64) radio frequency identification antennas,
• wherein each antenna comprises a coil etched into said circuit board, with each coil centrally located within a square of said chess board, wherein the width of each said coil is approximately 55% of the width of each square of said chess board.
