AbigailII:yes, bingo ... this is the whole idea ( I was thinking about wrapping, not cutting in half, but it works the same way) ...
This is why I do not call it "new game" but "new way of playing" ... it's different like any other spherical version is different from basic form of chess ... it stretches our perception and make the game a little bit more complicated ... more surprises are guaranteed ...and first of all, it can be fun and refreshing ...
Thank for your input ...
