[ucpguony] Magnetic blitz chess

A magnetic chess set would be the obvious way to avoid pieces being knocked over in blitz chess. Put the magnets in the board to avoid pieces from accidentally attracting each other.  The pieces simply have an iron base. A piece placed slightly off the center of a square would shift itself automatically to the center.

In contrast to the previous idea, we are relying on the electromagnetic force instead of the gravitational force.

The next challenge is to also have the board automatically record moves as the professional pressure sensor boards do.
