I'm currently testing boards. I have a gold and black lacquered board, but my testers tell me that the gold squares give the player an unfair advantage as their outlook is always brighter.
I'm building a bare metal board with brass and bronze squares - but the British Chess Society have told me it might lower the tone of the game.
Think you would have to make a special veggie one for OG though.
