STRA-TAC [The Logical Evolution of Chess] Box Set

New, mathematically designed and patented board to accommodate four (4) players instead of the two (2) traditional players in Chess. Each of the four (4) players have an eighteen (18) piece playing set instead of the sixteen (16) piece set played with in traditional Chess.
Now,  Four (4) players can play against each other in a “Free for All” or teams of two (2) can combine their intellect and challenge the others.
