Equipment: * A standard chess set and board * 4 pieces that represent the Yin and Yang contained in both teams: one clear stone, one translucent black stone, one opaque white stone, and one opaque black stone Praxis is a chess variant that incorporates the Zen philosophy of opposing forces defining the Way. Ancient books, such as the I Ching, show the interaction of these two forces, Yin and Yang, and their effect upon human life. Praxis is an attempt to bring these forces into a game that already presents the struggle between opposing forces. From the game's designer: 'This is a Chess variant I created in college. I uncovered it in a recent basement purge. I scanned it and posted the scans then destroyed the original due to mildew damage. Once you get over the early 90's graphics... it might just be playable!'
